Development of an Inverse Technique to Estimate the Ultrasound Field during Chest Wall and Breast Hyperthermia.

摘要

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 of hypethermia cancer treatments. With this improved model the clinician can plan an ultrasound hypothermia treatments so as to produce the required thermal dose while minimizing patient pain due to excessive temperature or ultrasound-tissue interactions. A clinical system is being constructed to combine model results with experiments in an inverse technique to estimate the absorbed power field in the breast and chest wall during ultrasound hypothermia. This improved planning will aid the clinicians in providing better hypethermia treatments which will improve treatment response rates.
