High-precision thermotherapy for small lesions.
Many applications of ultrasonic therapy involve treatment within small tissue volumes. This situation is encountered in ocular therapy, and it requires precise lesion control and high-resolution monitoring techniques. This report describes our system for ophthalmic thermotherapy and summarizes our mathematical model describing how tissue parameters and exposure parameters influence lesion size and shape for short, ablative exposures. It also describes our clinical approaches to producing specific lesion features and presents illustrative experimental results that indicate areas for future study.
