Abstract
A transducer for use with a high intensity focused ultrasound medical system has transducer elements that are made from a piezocomposite material bonded together in turn with an adhesive. The elements are deployed along a surface of a geometric structure with two curvatures. The structure is a truncated curved cylinder. The transducer also includes electrodes, each of which is arranged on a corresponding one of the transducer elements for exciting the transducer elements to emit ultrasonic waves in response to electrical signals applied to the electrodes to steer the waves to form a common focus zone in a desired heating area.
