Patent ID: 7993289

Claim:
A system for the application of energy into a body region, the system comprising: a base unit containing a therapy controller; a mechanical arm having a proximal end and a distal end, the proximal end being mounted to said base, the mechanical arm having a plurality of degrees of freedom; and a scan head movably mounted to the distal end of said mechanical arm, the scan head comprising: an upper chamber having two motor drive units operating in coordination to move two traveler rods; at least one encoder coupled to each motor drive unit for determining the position of the traveler rods; and a lower chamber having (1) an interior filled with a coupling fluid and sealed from the upper chamber by a wall having at least one aperture for receiving said traveler rods and (2) an energy aperture at a lower end thereof for broadcasting energy from the scan head; and a slotted actuator connected to each traveler rod to be rotated by the motor drive unit; an energy applicator within the lower chamber and removably attached to said slotted actuators wherein said motor drive units operate to move said energy applicator over the energy aperture within the confines of the lower chamber; and at least one electronic unit connecting the therapy controller, said motor drive units, said encoder(s) and said energy applicator such that the therapy controller is in electronic communication with said motor drive units, said energy applicator and said encoder(s) such that the therapy controller can control the position of the energy applicator within said lower chamber based on data received from said encoder(s).
