Abstract
An MRI safe robot for guiding transrectal prostate biopsy comprises a support arm, a robot body operatively connected to the support arm and a transrectal biopsy device operatively connected to the robot body. The transrectal biopsy device includes an endorectal extension and a biopsy needle device, the endorectal extension including an MRI coil for MRI imaging of the prostate. The robot body includes a first driver module for generating rotational motion of the endorectal extension and a second driver module for angulating the biopsy needle device toward a target area of the prostate for biopsy. The biopsy needle device is rotatable relative to the endorectal extension about a fixed axis and translatable through the endorectal extension. Each of the first and second driver modules include at least one pneumatic motor, wherein the MRI images are used by a physician to determine the target area for biopsy.
