MRI-guided prostate interventions and role of robots
Abstract: Prostate cancer is one of the leading causes of death in men. Prostate interventions using magnetic resonance imaging (MRI) benefits from high tissue contrast and anatomic details if compared to other imaging modalities. This talk will present a few examples of how robots can improve MRI-guided prostate interventions using two cases: prostate biopsy and focal cryoablation. Currently, MRI-guided biopsy is time-consuming and indicated a specific group of patients. This type of procedure faces several challenges, such as space constraints, MRI-compatibility of tools and 3D needle visualization. Many research efforts have been made along the past 15 years on the robot and computer-assisted prostate biopsy. On the other hand, the development of tools for focal cryoablation is still incipient. The ability to treat recurrent tumors and the advancements on cryo-systems promoted the prostate cryoablation as a suitable treatment for post-radiation recurrences. This talk will introduce our ongoing research on preoperative planning of MRI-guided focal cryoablation and the impact of accurate cryo-needle on the clinical outcomes.
Bio: Pedro Moreira joined the Department of Radiology at the Brigham and Women's Hospital and the Harvard Medical School as a research fellow in 2017. He was a Postdoctoral fellow in the Surgical Robotics Laboratory at the University of Twente (The Netherlands) from 2013 until 2016. He obtained his M.Sc. degree in Electrical Engineering from the Federal University of Rio de Janeiro (Brazil) and received his Ph.D. degree in Automatic Systems and Microelectronics from the University of Montpellier (France). Before his Ph.D., he worked for six years at the Electric Power Research Center in Brazil. His main research interests are surgical robotics, MRI-compatible robots, needle steering, and control theory.
