Three-Dimensional Stochastic Organ-Models For Segmentation In CT-Scans
Nico Karssemeijer · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
A statistically based relaxation method is applied to segmentation of abdominal X-ray CT-scans. To incorporate prior knowledge about the anatomical structure a stochastic model representing the geometry of the abdomen is used. Properties of each tissue class with respect to X-ray imaging are modelled by mean grey value distributions. The performance of the segmentation procedure has been tested on a set of 18 scan-sequences.
