Abstract
An ultrasound transducer for use with an ultrasound brain lesioning system includes an acoustic focusing lens, a piezoelectric transducer plate disposed in spaced relation with the focusing lens, an acoustic coupling medium disposed between the focusing lens and the transducer, and a pressurized fluid contacting the rear surface of the transducer to maintain a spaced relation between the transducer plate and the back surface of the lens. An electrical excitation signal is supplied to the transducer to promote production of an ultrasonic signal by the transducer.
