Abstract:
1. A method for use in transrectal ultrasound guided biopsy, comprising: receiving a 3D image of a prostate gland at a processor; processing said 3D image to delineate a urethra in the 3D image of said prostate gland, wherein the urethra is delineated using a series of at least three non-collinear control points identified in at least a first image of the prostate gland, at least a first of said at least three non-collinear control points represents a first intersection of the urethra with a surface of the prostate gland and at least a second of said at least three non-collinear control points represents a second intersection of the urethra with the surface of the prostate gland; using the delineated urethra, processing the 3-D image to define a mid-plane dividing the prostate gland into first and second lateral portions; based on said defined mid-plane, generating at least one plane transverse to the mid-plane such that the prostate gland is divided into at least one upper portion and at least one lower portion, wherein said mid-plane and said at least one plane define a plurality of zones in said 3-D image of said prostate gland; generating a prostate zone image such that said plurality of zones are displayed on the 3-D image of the prostate gland; and generating at least one biopsy target point in at least one of said plurality of zones, wherein said biopsy target point is displayed on said prostate zone image.
