AJR papers shine spotlight on cinematic rendering
It's been touted as "3D on steroids," but many in radiology still aren't sure how cinematic rendering of medical images works. Fortunately, two papers in the August edition of the American Journal of Roentgenology offer an explanation of the new technique, which creates stunningly lifelike images from scans.
