Synopsis

Keywords: Interventional Devices, VisualizationUtilizing MR guidance for minimally-invasive prostate interventions is known to improve the precision and accuracy of the procedure. Previous work has been done to develop and propose an integrated platform for conveniently providing this image guidance to clinicians for use with transperineal prostate interventions. Since then, the proposed methodology has been applied, in a limited capacity, to assist in an in-vivo prostate biopsy. It was found that the trajectory computation component of the platform was able to accurately guide needle placement to the clinician-selected anatomical regions with little need for correction.
