This invention generally relates to medical image processing, and particularly to a method of producing a computerised boundary estimation in medical images using a Radial Bas-Relief technique. It utilises a surgical robot having a head axis, a computer equipped with a frame grabber, a four-axis motion controller, an ultrasound scanner, and one of a transurethral and a transrectal ultrasound probe which passes through an outer/sheath of a resectoscope mounted to said surgical robot. An imaging probe can be carried by a robot and shares the same reference frame as the robot. The prostate, for example, is scanned and the ultrasound images are fed into a computer which provides computational images processing. This provides a quick and robust extraction of the prostate boundary from images taken transurethrally or transrectally.
