A therapy head for use in HIFU procedures is described. The therapy head has an enclosure with a window, an energy applicator and a means of moving the energy applicator within the enclosure. The therapy head uses motors and actuators to move the energy applicator, usually an ultrasound transducer, inside the enclosure. A controller is provided either internally or externally that allows the therapy head to identify and distinguish locations where the therapy head should be to radiate energy into a patient. The controller uses the motors and actuators to move the energy applicator into the desired locations.

A two-stage control system is disclosed being made of a first control means for providing command and control of a robotic arm, and a second control means for the control and movement of a therapy device, such as an ultrasound transducer. The therapy device is positioned within a therapy head. The therapy head is attached to the distal end of the robotic arm. The two-stage control system provides for a macro and micro level of control for the therapy device during a therapy procedure.

HIFU therapy to a desired tissue site is controlled based on detected changes in one or more characteristics of a received backscatter signal resulting from exposure of the tissue to HIFU or other interrogation signals. In one embodiment, the bloom of backscatter signals outward from a treatment region (e. g. , towards the HIFU transducer) is detected and monitored. Once the bloom reaches a predetermined location, treatment is stopped. Other signal characteristics such as angular distribution of frequency components in the backscatter signal, changes in reflection, power required to saturate a tissue characteristic, changes in attenuation and changes in a cumulative energy distribution function of the backscatter signal that change as a result of the application of HIFU power are also used to control the delivery of HIFU signals in accordance with other embodiments of the disclosed technology.

Described is a system and method for the destruction of adipose tissue using an energy applicator such as a HIFU transducer. The system has a scan head containing an energy applicator, a mechanical arm for carrying the weight of the scan head, and a therapy controller such as a computer for controlling the operation of the scan head. The therapy controller may be part of a general purpose computer, and may be used as a robotic controller to automate the procedure. Methods are included for destroying adipose tissue in a quick, non-invasive manner.
