Analysis of Power Deposition Patterns and Ultrasonic Phased Arrays for Localized Hyperthermia

This thesis examines theoretically the determination of the desired power deposition pattern for localized hyperthermic treatment and the potential for providing precision local hyperthermia by using ultrasonic phased arrays. A method for calculating ultrasonic fields and examples of field patterns produced by square ultrasonic sources are presented. Temperature distributions are calculated from power deposition patterns by using a finite difference solution to the bioheat transfer equation. The combination of these two methods allows calculation of temperature distributions produced by a given applicator design.
