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.

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.

Surgical planning with immersive mixed reality

01/04/2021

The 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.

Gamification: how penguins help children overcome their MRI fear

23/04/2019

It'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.
