Title: Real time mechanical imaging of the prostate

Abstract: The present invention relates to a method for real time mechanically imaging the prostate with a transrectal probe. In the method, the prostate image is synthesized and displayed in real time during the examination process. In a preferred embodiment, a compact prostate examination device comprises a probe sized to fit within the rectum and having a head with a tactile sensor longer than the axial length of an average prostate, an electronic unit and a display. As the pressure sensing part of the head is pressed against and moved over the prostate, it generates signals characterizing mechanical structure of the examined area. An accelerometer based motion tracking system is mounted in the probe for determining the position of the pressure transducer array during prostate examination. The electronic unit incorporated into the handle of the probe receives the pressure and motion data to calculate mechanical and geometrical features of the prostate and displays it on the display.
