METHOD AND DEVICE FOR IMAGING THE PROSTATE

摘要

A device and method for visualizing geometrical and mechanical parameters of prostates and diagnosing prostate diseases using a pressure sensor array (101) is disclosed. A probe (100) having an articulated tip (102) for insertion into the rectum applies digital pressure to the prostate similar to that applied by a human finger. A pressure and position oriented sensor (103) is provided in the tip (102). Signals from the array (101) are used to calculate a virtual pattern of a property such as stress and strain. The virtual and theoretical patterns are compared and differences are used to indicate the presence and location of differing elasticity regions of the tissues being examined and to display an image of the examined prostate.
