Claim 49:
50. A method of forming a fluid impermeable ultrasonic transducer, the method comprising:
forming a substantially hollow casing from a fluid impermeable material having an internal cavity and a closed first end defining a transducer head element, wherein the fluid impermeable material comprises titanium;
forming a focusing lens on a front surface of the head element, the focus lens configured to focus ultrasound towards a focal point;
bonding an actuator to a back surface of the transducer head element opposite the front surface, the actuator operable to generate oscillatory mechanical vibration of the focusing lens so that ultrasound is emitted from the focusing lens toward the focal point;
forming a peripheral portion surrounding the focusing lens; and
forming an attenuation layer interfaced with the peripheral portion, the attenuation layer configured to absorb ultrasonic energy emitted through the peripheral portion from the actuator, wherein the front surface of the head element comprises the peripheral portion and the attenuation layer.
