Real-time 3D MR Thermometry for Focused Ultrasound Surgery

Project Name: Real-time 3D MR Thermometry for Focused Ultrasound Surgery
Status: Complete
Primary Site: University of Virginia Health System
Sponsor Organization: Focused Ultrasound Foundation
Funded Date: Jun 10, 2013
Funding Period: Jun 10, 2013 - Jun 09, 2014

Category: Technical
Amount Awarded: $100,000.00


MR temperature mapping is an integral element of MR-guided focused ultrasound surgery (FUS). However, acquisition of the MR images required for calculating a temperature map is time consuming, so that it is not possible using conventional nonaccelerated MR techniques to acquire and reconstruct a 3D temperature map in realtime. In this study, we will use spiral k-space scanning and a new accelerated MR technique that we have developed to acquire, reconstruct, and display 3D temperature maps in real time. A new real-time method for 3D MR thermometry would have a major impact on the safety, efficacy, and procedural efficiency of FUS.
