Computers are already capable of creating a 3D scan of a patient’s heart. In 4D, a new model is created for every 3D frame, essentially mapping the motion of the heart. The developers have achieved this by applying a ‘multi-atlas’ technique.
“Our approach was to estimate the motion between the different images, compensate for this motion, and overlay the different images. Using this multi-atlas technique, we were able to create high-quality models that our partners in the consortium could move forward with,” clarifies professor Jef Vandemeulebroucke from ETRO, an imec research group at VUB.
