Stunning example of what is now possible, with advanced, hi-resolution CT scanners. The image produced on the right, courtesy of Univ. Medical Center, Gottingen, Germany, shows an example of what is termed "cinematic" rendering of a tomographic image. Compared to the 1974 vintage image, this is a real leap forward. What is significant, is how neural-network technology is being used to process CT scans, and determine if tumors are present. This is perhaps one of the most promising immediate uses of what are termed "deep learning" neural network techiques. If the tumor is present, then by definition, the image data that describes the tumor is also likely to be present, given that sufficient resolution is possible.
