Abstract
A prototype 64-element, 75° cylindrical-section ultrasonic phased-array hyperthermia applicator has been designed and constructed. The ability of this applicator to focus ultrasonic energy at its geometric focus was verified in a water medium. The array was then driven by excitation vectors obtained using the pseudoinverse pattern synthesis method to generate shifted-focus and double-focus field patterns. The measured intensity profiles agree well with the theoretically predicted ones.
