Claim 0:
1. A fluid impermeable transducer, comprising:
a fluid impermeable metal casing;
a fluid impermeable transducer head comprising a metal focusing lens, wherein the fluid impermeable transducer head and the fluid impermeable metal casing comprise titanium, the fluid impermeable transducer head having a back surface and a front surface, the metal focusing lens being disposed on the front surface and configured to focus ultrasound towards a focal point; and
an actuator bonded to the back surface of the fluid impermeable transducer head and operable to generate oscillatory mechanical vibration of the metal focusing lens so that ultrasound is emitted from the metal focusing lens towards the focal point, wherein the fluid impermeable metal casing and the fluid impermeable transducer head are integrally formed as a single part and permanently connected in a fluid impermeable manner to prevent ingress of liquid into the fluid impermeable metal casing, wherein the front surface of the fluid impermeable transducer head comprises:
a peripheral portion surrounding the metal focusing lens; and
an attenuation layer interfaced with the peripheral portion and configured to absorb ultrasonic energy emitted through the peripheral portion from the actuator.
