Edge guided delineation of the prostate in transrectal ultrasound images

Prostate boundaries form the basis of many diagnosis/treatment procedures for prostate diseases. In this paper, a new paradigm of edge guidance is described that involves just-enough-interaction with the expert, leading to robust delineation of the prostate boundaries. We statistically show that an increase in the consistency and the accuracy of prostate delineation is achieved using the edges as visual guide.
