Title: Method and a dual-array transducer probe for real time mechanical imaging of prostate

Abstract: The present invention relates to a transrectal probe and method for real time mechanical imaging of a prostate. The probe is equipped with dual-array pressure sensors--one on the probe head and another on the shaft of the probe spaced away from the head with an angular and linear offset forming an S-shaped transition between the shaft and the head of the probe. The addition of the shaft pressure sensor array together with orientation tracking sensors allows precise calculation of the current head position throughout the examination of the prostate. Display means are used to guide the user in the proper manipulation of the probe in order to reduce the forces on surrounding tissues and organs and to minimize patient's discomfort.
