AI helps to correct distortions in in vivo photoacoustic images of humans

26/11/2021

Obtaining an accurate speed of sound (SoS) inside the body leads to improved resolution of ultrasound or photoacoustic (PA) images. However, it is difficult to accurately predict the SoS since it differs from person to person, depending on the random distribution of muscle, bone, and fat in each individual.

Development of artificial intelligence technology for producing CT images based on MRI

10/11/2021

Transcranial focused ultrasound can be used to treat degenerative movement disorders, intractable pain, and mental disorders by delivering ultrasound energy to a specific area of the brain without opening the skull. This treatment must be performed with an image-based technology that can locate the brain lesions. Doctors typically use CT to obtain information about a patient's skull.

Precision focused ultrasound surgery technology destroys only desired tissue

05/11/2021

There are ongoing efforts to use ultrasonic effects with non-invasive properties to replace existing surgical procedures. Focused ultrasound-based bio-tissue destruction technology, which can mechanically fractionate the surrounding bio-tissue using a powerful bubble (cavitation) generated at a short time of approximately 1/100th of a second at the ultrasound focal point.

Point-of-care ultrasound helps in emergency diagnosis

01/06/2021

Medical emergencies require quick action and prompt decisions: Point-of-care ultrasound (POCUS) is a valuable diagnostic tool available to the emergency physician. Rather than relying on his/her gut feeling, the device answers specific clinical questions that narrow differentials. The question is, in which settings does POCUS deliver the biggest benefits?

Faster treatment thanks to point-of-care diagnostics – in emergencies and beyond

01/06/2021

Making an informed and immediate treatment decision near or at the patient’s bedside – point-of-care testing (also known as POCT) makes this possible. Unlike stationary devices, special exam rooms or other service infrastructure, POC diagnostic devices offer a multitude of benefits including more flexibility, faster results, and lower costs.

Broader perspective: how Mixed and Virtual Reality transform surgery

01/04/2021

For 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.

Augmented reality ultrasound: putting the focus on patients

10/08/2020

This 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.
