ABSTRACT:
The present invention relates to a method for mechanically imaging the prostate with a prostate examination device. In the method, position data and pressure response data are acquired along predetermined trajectories overlaying the prostate by periodic pressing or sliding of a pressure sensor assembly attached to a probe against the prostate. In a preferred embodiment, the prostate examination device comprises a probe sized to fit within the rectum and having a head connected by a shaft to a handle. A support is connected to the probe for providing a point of rest for the shaft during the prostate examination. As the pressure sensor assembly is pressed against and moved over the prostate, it generates signals in response to forces imposed on the pressure sensor assembly. A positioning system is coupled to the support and probe for determining position data of the pressure sensor assembly during prostate examination. An electronic unit receives the data from the pressure sensor assembly and the position data from the positioning system and determines a structure of the prostate.
