Multiple Tissue Sample Collection Device for MRI Guided Transrectal Prostate Biopsy: Optimization and MRI Compatibility Tests

A MRI Compatible Device for MRI Guided Transrectal Prostate Biopsy

This paper reports a novel remotely actuated device for transrectal prostate biopsy, designed for use in a conventional high-field MRI scanner. The device provides three-dimensional MRI guided biopsy needle placement with sub-millimeter accuracy under physician control. Its compact size enables use in both closed and open configuration MRI scanners. Preliminary in-vivo canine experiments demons...

MRI-Guided Transrectal Prostate Intervention System

MRI-safe robot for targeted transrectal prostate biopsy: animal experiments.

OBJECTIVES To study the feasibility and safety of using a magnetic resonance imaging (MRI)-safe robot for assisting MRI-guided transrectal needle placement and biopsy in the prostate, using a canine model. To determine the accuracy and precision afforded by the use of the robot while targeting a desired location in the organ. MATERIALS AND METHODS In a study approved by the Institutional Anim...

Introduction of a new robotic technique for MRI-guided transrectal prostate biopsy: safety and accuracy aspects

Prostate contouring in MRI guided biopsy.

With MRI possibly becoming a modality of choice for detection and staging of prostate cancer, fast and accurate outlining of the prostate is required in the volume of clinical interest. We present a semi-automatic algorithm that uses a priori knowledge of prostate shape to arrive at the final prostate contour. The contour of one slice is then used as initial estimate in the neighboring slices. ...
