The present invention relates to a transrectal probe and method for real time mechanical imaging of a prostate with a transrectal probe. In the method, generating a composite two- and three-dimensional prostate mechanical image from a plurality of partial mechanical images extracted from pressure response data and a probe orientation data starts with examining the prostate by pressing a probe head pressure sensor array against it at various overlapping locations. Merging of partial mechanical images together is then accomplished. Finding the prostate is assisted with a supplemental pressure response data indicating the location of a sphincter. Data processing is improved by including probe orientation data to further increase the accuracy and sensitivity of the method. 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 is 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.La présente invention concerne une sonde transrectale et un procédé pour une imagerie mécanique en temps réel dune prostate au moyen dune sonde transrectale.
