01/12/2021Cochlear implants are devices that partially restore hearing in wearers. Unfortunately, the signal transmission from the implant to the auditory nerve is still rather basic, thus limiting the sound quality. Future implants could be more accurate in this setting by using light versus electrical pulses to stimulate nerve cells in the ear.
26/11/2021A lot of laboratory tasks require high precision on one hand, on the other they tend to be repetitive and tiring. While humans can only work for a limited time here while staying effective, robots are able to work without taking a break. The start-up bAhead wants to make collaborative robots, CoBots, adaptable helpers with the help of AI. We learn more from CEO & Founder Rainer Treptow.
24/11/2021Instead of surgically removing a sample of skin, sending it to a lab and waiting several days for results, your dermatologist takes pictures of a suspicious-looking lesion and quickly produces a detailed, microscopic image of the skin.
22/11/2021Orthopedic auxiliary means are mostly still produced in manual labor today. But orthopedic technology is also trying out new ways by using tools like 3D scanners, digital models and 3D printing. Nadja Singer from Ottobock explains in our video interview how this changes the production of auxiliary means.
02/11/2021Take a nice, deep breath. Now imagine your lungs: myriad airways like branches, each with tiny alveoli like leaves. This alveolar structure is key to the absorption of oxygen and excretion of carbon dioxide that we call "breath." As we breathe, the volume of gases in the lungs is continually changing with varying degrees of inhalation and exhalation.
29/10/2021Bioengineers and scientists at The University of Texas at Arlington, in collaboration with Austin’s Shani Biotechnologies, LLC, have developed a new noninvasive technology that may help real-time monitoring of key blood parameters, such as hemoglobin, especially in Black patients.

The further development of imaging techniques represents a forward-looking field of research in order to be able to improve surgical treatment.
02/08/2021Image-guided surgery is based on medical imaging. However, past imaging technologies performed while the patient is awake cannot deliver a complete view that facilitates a visual differentiation of structures such as blood vessels and nerve tracts. In a study, scientists developed a non-invasive imaging modality that enables multiplexing, deep tissue penetration, and real-time resolution.
01/07/2021Orthopedic technology involves taking a measurement of a specific body part and then creating a medical device, be it prosthesis or orthosis, that fits. While optical scanners are already used for some of these measurements, others are still performed through manual labor and craft to create molds of the body. 3D scanners are changing this.
22/03/2021Alzheimer's disease is still incurable, but if detected early enough, countermeasures can improve treatment and slow the progression. Unfortunately, there is still no reliable early detection test at this juncture. This might soon change thanks to a non-invasive spectroscopy of the retina.
01/02/2021Today we use implants to stabilize or compensate for injuries inside the body and to aid in the healing process. Implants cannot act autonomously and treat the patient if they deem it necessary. However, it is just a matter of time before this happens because research on intelligent implant materials that respond to stimuli is on the cusp of a breakthrough.
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.
01/09/2020Accuracy is paramount in laboratory settings and ensures that lab results are valid. Errors in a lab can render series of tests unusable and waste precious time and money. In the medical realm, this might even result in clinical trial errors. Augmented reality (AR) can help laboratory technicians to prevent errors and guide their work in the future.
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.
03/08/2020Delirium occurs in 30 to 80 percent of patients in intensive care units.

A controlled circadian rhythm and sleep/wake cycle is the prerequisite for delirium prevention. This is where the new VitalMinds concept from Philips comes in.
08/06/2020Professional athletes depend on a speedy recovery from sports injuries or surgery because their livelihood depends on their physical fitness. Returning to competition too soon after injury can have negative health consequences. Standard tests are now combined with virtual reality to determine the optimal time to return to play.
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.
03/02/2020Regenerative medicine aims to replace damage in the body with functional tissue and restore normal function. The first defense for large defects are implants made of hydrogels, designed to promote cell growth. They need their own blood supply, which is a problem when it comes to larger implants because you cannot regulate where and how the blood vessels grow - until now.
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.
01/01/2020When natural joints lose their ability to function, they can be completely or partially replaced by artificial joints, also called endoprostheses. Endoprostheses must be of a certain quality, as they should remain in the body as long as possible. In addition to some risks, endoprostheses can also contribute to a mobile and carefree life for young and old.
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.

Now, the finalists, who will showcase their innovations at the MEDICA 2019 trade fair have been selected.
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.
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.
01/04/2019In 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.

01/02/2019The liver, nervous tissue or the intestines: all are important human organs that have in the past been tested for their function and compatibility using animal or in vitro test methods. In recent years, TissUse GmbH, a spin-off of the Technical University of Berlin (TU Berlin), has launched multi-organ chip platforms. But that’s not all.
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.
02/01/2019Diabetes mellitus or simply diabetes has become very common and is often described as a lifestyle disease. More and more people are suffering from this chronic metabolic disorder. Next to established diagnostic procedures, digital retinal screening has shown to be successful - a promising technique that will also play an important role in the diagnosis of other diseases in the future.
02/01/2019There are 425 million people with diabetes in the world. Heart problems, kidney failure or blindness - these can all be consequences of the metabolic disease. Diabetes patients now have the possibility of being treated digitally.
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.
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.
22/03/2018Virtual reality and medicine are increasingly mentioned in the same context. In addition to the development of applications that support the treatment of patients suffering from chronic pain and anxiety, this technology also benefits medical staff.
