13/04/2021New insights into the three-dimensional (3D) morphology of the human uterine endometrium could advance our understanding of the mechanisms of endometrial regeneration and fertilized egg implantation while clarifying the pathogenesis of menstrual disorders, infertility and endometrium-related diseases such as adenomyosis, endometriosis, endometrial hyperplasia and endometrial cancer.
01/04/2021The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.
01/04/2021Surgeons do not only have to gather theoretical knowledge and practice to perform successful interventions. They also need a good visual thinking and have to know the anatomical characteristics of each individual patient. Some of these tasks will become easier when Virtual and Mixed Reality bring three-dimensional, digital models into their profession.
01/04/2021For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.
01/04/2021First of its kind 3D organoid models of nasopharyngeal cancer help to fine-tune radiation doses, and lower the chances of Nasopharyngeal Cancer recurrence and reduce mortality rate.
01/04/2021How do viral pathogens succeed in penetrating human cells?

18/03/2021Deep learning is a potential tool for scientists to glean more detail from low-resolution images in microscopy, but it is often difficult to gather enough baseline data to train computers in the process. Now, a new method developed by scientists at the Salk Institute could make the technology more accessible - by taking high-resolution images, and artificially degrading them.
15/03/2021Heart surgery is difficult even for experienced surgeons and therapeutical success is not always certain. Physicians need to rely on their experience when choosing and planning the correct intervention. A computer model could help them in the future: The digital twin heart could be fed with patient data and then simulate whether an intervention will be successful.
12/03/2021To highlight tumours in the body for cancer diagnosis, doctors can use tiny optical probes (nanoprobes) that light up when they attach to tumours. These nanoprobes allow doctors to detect the location, shape and size of cancers in the body.
12/03/2021Magnetic resonance imaging (MRI) is already widely used in medicine for diagnostic purposes.

26/02/2021Muscle soreness and achy joints are common symptoms among COVID-19 patients. But for some people, symptoms are more severe, long lasting and even bizarre, including rheumatoid arthritis flares, autoimmune myositis or "COVID toes." A new Northwestern Medicine study has, for the first time, confirmed and illustrated the causes of these symptoms through radiological imaging.
24/02/2021Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood. Thanks to a new analytical technique, scientists are getting a clearer view of the microenvironments found within adipose tissue associated with obesity.
24/02/2021According to an open-access article in ARRS' American Journal of Roentgenology (AJR), COVID-19-related disseminated leukoencephalopathy (CRDL) represents an important - albeit uncommon - differential consideration in patients with neurologic manifestations of coronavirus disease (COVID-19).
22/02/2021Researchers from Hanover Medical School (MHH), Mainz University Hospital and HELIOS University Hospital Wuppertal at Witten/Herdecke University are leading an international, multidisciplinary consortium that makes high-resolution, three-dimensional X-ray images of the human body possible.
18/02/2021Anyone needing a tomography gets the clearest possible images of an organ or other body structure slice by slice. But the further inside the potential problem lies, the more difficult it is to obtain high-resolution images in magnetic resonance imaging. An international team of scientists has developed a high-frequency coil that allows for much better range inside the body, among other advantages.
08/10/2020Surgery can be very strenuous for a surgeon, as he often has to bend over the patient in a rigid position for hours. For the first time worldwide, a surgical microscope that can be controlled by head movements was used at the University Hospital Zurich. This makes surgery not only more comfortable, but also faster.
24/08/2020For the annual MEDICA trade fair, companies from all over the world assemble in Düsseldorf. The Israel Export Institute has been a part of it for the last couple of years. They present medical devices and digital innovations from different Israeli companies at their joint booth.
10/08/2020This is how a conventional ultrasound scan works: patients lie down on a table next to the ultrasound machine. A doctor uses a probe to scan the part of the body in question, while he or she looks at the pictures on a monitor. In other words, the physician either focuses on his/her hand on the patient or the monitor. The Fraunhofer IGD wants to change this process as part of the "sonAR" project.
02/06/2020"Time is brain!" – a fundamental rule in stroke care because time is of the essence when brain regions are undersupplied with oxygen and glucose. If circulation is not restored quickly, brain damage can be permanent. However, the key point here is not just to "be fast", but also to "use the time to treat stroke effectively".
02/06/2020After a stroke, a patient’s life depends on getting acute care at a hospital. Vital monitoring systems ensure safe and effective treatment. An innovative tomographic imaging system is designed to help prevent the patient’s risky journey to radiology and to enable bedside monitoring of cerebral blood flow.
02/06/2020Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.
08/04/2020The University Hospital Bonn has recently introduced an ultrasound device that's small enough to fit in your coat pocket. It's ready to use once you have connected it to a tablet or smartphone. The portable system makes bedside physical exams possible. The device primarily benefits students as it allows them to combine basic knowledge and clinical application.
09/03/2020Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.
22/01/2020Patients have to undergo a gastroscopy to rule out gastrointestinal conditions. Many dread this procedure since a thin, flexible tube is being pushed through the esophagus and stomach. Ovesco Endoscopy AG has teamed up with other project partners in the nuEndo research project to develop a capsule endoscopy device that is tiny, easy to swallow and makes the test more comfortable for the patient.
01/01/2020Joints can suddenly or gradually deteriorate and lose their natural strength, whether it’s due to accidents, diseases or simple wear and tear. In some of these cases, implants of artificial joints – endoprostheses - can help. As a joint replacement, they are designed to stay in the body for as long as needed and as such improve the patient’s quality of life and mobility.
01/01/2020Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.
14/11/2019Acute respiratory distress syndrome (ARDS) is a life-threatening illness in which the lungs are severely damaged. The condition always requires intensive medical care through mechanical ventilation. But not all lungs are the same. To ensure a personalized treatment that is adapted to the individual patient’s lung volume and condition, Ebenbuild relies on digital twins.
04/11/2019Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.
04/11/2019Artificial intelligence holds the promise of salvation when it comes to medicine: it is meant to unburden medical professionals, save time and money and perform tasks reliably and tirelessly. But before AI algorithms are allowed to diagnose diseases, many technical and ethical questions still need answers.
01/10/2019Pneumonia, COPD or cystic fibrosis – people with such lung diseases have to consult their doctor regularly. Little children have to undergo certain measurements by the doctor, too. In order to save people`s need to visit a doctor, telemedicine offers many ways to do examinations at home.
02/09/2019More patients, more examinations, more CT images – in radiology there is too much work for too few physicians. CT scans are evaluated in the shortest possible time, which leads to anomalies being overlooked. Artificial intelligence, on the other hand, works with constant speed and performance, which is why radiological routine increasingly relies on its support.
02/09/2019In modern medicine, especially in the field of imaging, huge amounts of data are produced – so much that radiologists can hardly keep up with diagnosing the images. Artificial Intelligence could be the solution to this problem. But how exactly can it help in this task? How can man and machine work together? And what else will be possible in the future with the support of intelligent systems?
02/09/2019Artificial intelligence is no longer a dream of the future in medicine. Many studies and initial application examples show that it sometimes achieves better results than human physicians. At Jena University Hospital, the work with AI is already lived practice. It is the first institution in the world to use algorithms in radiological routine to reconstruct CT images.
02/09/2019Radiology is a field that produces large volumes of data, which can no longer be managed without the help of intelligent systems. This is especially true when it comes to the interpretation of medical images. While this takes physicians years of training and experience, several hours of work and the highest level of concentration, AI only requires a few seconds to accomplish the same task.
22/08/2019The German Medical Award will take place on November 18, 2019, as part of the MEDICA trade fair in Düsseldorf. The ceremony emphasizes the commitment to excellence in cutting-edge care for patients. Doctors, clinical centers and companies in the medical and healthcare industry can demonstrate their achievements in medicine and management in hopes of receiving the coveted award.
08/08/2019After their tumor has been removed, some patients have to return to the hospital to undergo surgery again. That's because the tumor was not precisely identified and was subsequently not completely removed. That's both an ethical and financial dilemma. A new surgery-adjacent procedure is designed to rapidly and accurately detect tumors.
22/07/2019Modern imaging opens news doors to surgeries. Yet it also poses major problems for surgeons: They use two-dimensional images to navigate through a three-dimensional surgical environment, while they continuously have to switch their focus back and forth between the images and the patient. Now help is on the way in the form of interactive 3D projections and mixed reality (MR).
24/06/2019Improving technology transfer from research to industry and driving robotics development - that's the idea behind the KUKA Innovation Award. This year’s topic is "Healthy Living". Applicants from around the world were tasked with creating a robot application for healthcare settings. Now, the finalists, who will showcase their innovations at the MEDICA 2019 trade fair have been selected.
11/06/2019Epilepsy patients are currently treated with either medication or surgical options. The aim is to remove the distinct regions of the brain that cause epileptic seizures. Laser ablation for epilepsy is a new, catheter-based surgical procedure that is now also available in Europe, preventing patients from having to undergo open brain surgery.
23/04/2019It's noisy, tight and scary - that's how children feel about a magnetic resonance imaging (MRI) machine. Because they are scared, they are often too fidgety and anxious during the procedure, causing the images to blur or the scan to be stopped. Researchers have now developed a VR app called Pingunauten Trainer that’s designed to gently prepare the little patients for MRI scans.
08/04/2019Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.
01/04/2019Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
01/04/2019All information from our body and the environment converges in our brain and is transformed into reactions in milliseconds. It is essential for medicine and research to know what our switching centre looks like. Functional methods are used to observe it more closely during work.
01/04/2019In an ischaemic stroke, rapid treatment is essential. In this moment good imaging data is particularly important to enable doctors to make the best possible decision for therapy. Modern CT scanners are increasingly being used to assess stroke patients because they can show the blood flow to the brain over time.
01/04/2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
01/03/2019People suffering from lung disease temporarily need ventilator support because they are unable to breathe naturally. Mechanical ventilation is designed to ensure the survival of these patients. The goal is to adapt the ventilator settings and tailor them the patient's specific needs and prevent lung tissue damage.
25/01/2019CT scan, MRI or X-ray: All these methods allow doctors to see inside the body - including inside the lungs - and make a diagnosis. The clinic for Nuclear Medicine at the RWTH Aachen University Hospital uses a state-of-the-art gamma camera that combines SPECT and CT.
19/12/2018Continuous monitoring is an essential process with every disease. In the case of eye disorders, frequent retina measurements can facilitate early detection of deterioration to quickly initiate intervention. This calls for comprehensive care settings, easy ways to take measurements and prompt results. However, in reality, this is rarely the case.
14/11/2018Whether CT, MRT, X-rays or ultrasound – imaging methods provide insights into the human body and are irreplaceable for diagnostics. They are part of everyday hospital life since a long time, but what is currently happening in this field? We took a look – at MEDICA 2018.
02/11/2018It's time: the world's largest medical trade fair opens its doors from 12 to 15 November. More than 5,000 international exhibitors will present their new innovative products and applications. Frums, conferences and special shows will feature exciting specialist lectures and discussions that will give you an insight into electromedicine, laboratory medicine, medical technology and diagnostics.
05/10/2018Many people have damaged or suboptimally functioning lungs. An accurate diagnosis and subsequent treatment are vital to protect this life-sustaining organ. Modern imaging solutions help physicians and patients understand what happens inside the lungs.
01/10/2018Lung cancer is one of the most common and deadliest cancers. The symptoms tend to be non-specific, often causing its detection to be too late. Currently, there is no comprehensive screening. This could change with the use of low-dose CT scans. It should be noted that this is not just an issue of technical feasibility. A screening test must also make sense from a health policy perspective.
01/10/2018Thanks to various imaging supplies, it is possible to make the inside of the body accessible for diagnostics, research and treatment. The lung, one of the most important human organs for survival, is also examined in this way. In our Topic of the Month, we looked at how doctors are getting a closer look at the lung, how the procedures differ, and which ones will be available in the near future.
01/10/2018A look inside the lungs is a time-consuming process. To identify the boundaries of the respiratory organ from surrounding other organs, tissues, and structures requires between 200 and 500 computed tomographic images and subsequent manual markings – an elaborate process that can take up to six hours. An optimized computer program is now able to do this in only a few seconds.
03/09/2018In a Smart Hospital, all devices are designed to be connected and integrated, thus increasing efficiency and reducing time loss – at least, that is how things are meant to work in theory. In reality, there are still countless vendor-specific point solutions that cannot be integrated. That's why there is a need for solutions that bridge the gap between the different applications and formats.
08/08/2018Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.
01/08/2018For years, medicine has been exploring AI techniques aimed at easing physician workload. While computers may not have the medical expertise and skills obtained through years of study, they can recognize patterns and specific features in datasets and draw deductions.
23/07/2018Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.
22/06/2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
21/06/2018Biomechanical measuring systems are used in orthopedics to diagnose and treat misalignments and diseases. The Velamed Company uses its high-tech solutions to measure biomechanical parameters that enable a holistic analysis of human movement and posture. We took a closer look at how this works.
17/05/2018Ventricular fibrillation is a life-threatening condition that occurs when the heart muscle exhibits a rapid, erratic beat. The cause might be a circulatory system disease or heart attack. Researchers in Göttingen are now developing an ultrasound technique to get to the bottom of ventricular fibrillation and cardiac arrhythmias and facilitate better treatment options.
02/05/2018X-rays for diagnostic imaging and therapy evaluation are still the norm in orthopedics. Meanwhile, patients who frequently need X-rays are repeatedly exposed to radiation. That's why the University Hospital RWTH Aachen uses and develops methods that are not just radiation-free but can also capture motions.
08/03/2018Automation makes work life easier in many ways but is it also a solution for analyzing medical images? Is a computer actually reliable enough to assist in the medical decision making process? Researchers in Landshut examine how machine learning algorithms can work more reliably and support radiologists.
06/03/2018With the help of surgical navigation systems, prostheses or implants can be better inserted. During the procedure, surgeons can see exactly where they need to operate on a screen. Just like a navigation system in the car, navigation in the OR guides you precisely to your destination. At the Uniklinik RWTH Aachen we can find out what advantages this has for physicians and patients.
08/02/2018When body tissue is reconnected during a tumor operation in the gastrointestinal tract, surgeons need information about the current state of these so-called anastomoses. The new, non-invasive hyperspectral imaging technology now makes it possible to measure the crucial parameters during surgery and thereby increase surgical precision.
04/01/2018Imaging, navigation, integration – these are terms that describe the modern operating room. All of these components play a key role in accurate surgical procedures. They are integrated into surgical navigation systems, which make complicated medical surgeries considerably safer.
04/01/2018While it is commonplace for operating room staff to work together as a team, the collaboration of operating room systems does not always work so well – many devices are still separated from one another, causing the OR processes to be prone to mistakes. The same applies to surgical navigation technologies that represent the interface between imaging, the surgeon and therapeutic devices.
04/01/2018The position and alignment of surgical tools in the patient’s body must always be kept in view during the operation process to guarantee success and safety. With fine sensors at the tip of the instruments and an electromagnetic signal, Fiagon's electromagnetic navigation systems accurately reproduce their position in the body.
