abstract = {Prostate cancer is a major health threat for men. For over five years, the U.S. National Cancer Institute has performed prostate biopsies with a magnetic resonance imaging (MRI)-guided robotic system. Purpose: A retrospective evaluation methodology and analysis of the clinical accuracy of this system is reported. Methods: Using the pre and post-needle insertion image volumes, a registration algorithm that contains a two-step rigid registration followed by a deformable refinement was developed to capture prostate dislocation during the procedure. The method was validated by using three-dimensional contour overlays of the segmented prostates and the registrations were accurate up to 2 mm. Results: It was found that tissue deformation was less of a factor than organ displacement. Out of the 82 biopsies from 21 patients, the mean target displacement, needle placement error, and clinical biopsy error was …},

abstract = {Prostate cancer, affecting one in every six men, remains the number one cancer-related death in men [1]. In the pursuit of more accurate biopsy, Krieger and Susil [2, 3] developed robotic assistance under MR image guidance. To date, their system has been used in 200+ biopsies at the US National Cancer Institute. A limited validation study was presented earlier [4]. Here we report a more comprehensive retrospective evaluation of the Krieger-Susil biopsy system. We analyze a larger set of patient data in an improved validation workflow and produce a formal statistical analysis and draw strong conclusions.},
