J2410107 Focus Control Aided by Numerical Simulation in Soft Heterogeneous Media for High-Intensity Focused Ultrasound Treatment

Abstract

To research heterogeneous-media focus aberration-related problems in low-invasive HIFU cancer treatment, focus control method based on time reversal aided by large-scale numerical simulation was implemented with phase arrangement on 256ch array transducer. As a continue observation to previous acoustic field research, numerical simulation on thermal field was performed. Besides, phase control method on thermal field is conducted, in order to acquire the temperature profile, which is significant in HIFU cancer treatments.
