Abstract

A control system has been developed to perform MRI-guided ' interstitial ultrasound heating in a closed-bore MR scanner. A prototype delivery system capable of positioning, rotating, and delivering RF power to a heating applicator has been built and algorithms for using temperature information as a source of feedback for the control system have been tested. Heating experiments indicate that the system is capable of producing repeatable thermal lesions. Simulations of heating with the control algorithm enable the automatic selection of parameters to achieve a conformal region of thermal coagulation.
