Abstract:

It is the goal of this research to provide improved numerical modeling of ultrasound propagation through breast tissue and the post mastectomy chest wall for use in patient treatment planning for hyperthermia cancer treatments. Progress in the third year has included the development of a 3D ultrasonic attenuation mapping technique based on signals collected from a modified medical B-scan unit, partial development of a patient registration and tissue geometry acquisition system based on the same B-scan hardware, and investigation of the accuracy of thermocouple measurements to determine ultrasound power incident at a point in tissue. The numerical model developed in the second year was packaged into a convenient usable form during the third year, and alternative inverse optimization techniques were investigated.
