Abstract: A subcutaneous fat treatment system and method. An electrode is for application to a patient's epidermis above subcutaneous fat to be treated. There may optionally be a cooling subsystem for cooling the electrode. A sensor such as a microwave radiometer measures the temperature of the subcutaneous fat to be treated. In addition or in the alternative, a subcutaneous fat thickness measurement may be used. A radio frequency source is for applying radio frequency energy to the electrode. A controller subsystem is responsive to the sensor and/or the subcutaneous fat thickness measurement and controls the radio frequency source to determine the thermal dose applied to the subcutaneous fat being treated and automatically adjust the radio frequency energy supplied to the electrode subjecting the subcutaneous fat to a thermal dose of between 0.1 and 10.0.

Abstract: A method and system for aesthetic skin treatment. The system includes a treatment energy source for generating a treatment beam and a treatment beam deflecting mechanism configured to direct the treatment beam to a treated skin area. One or more video cameras configured to capture a treated skin area and communicate captured treated skin area image to a processor. Based on a captured treated skin area the processor constructs a three-dimensional representation of the captured skin area and controls a treatment energy beam deflecting mechanism to deflect the treatment energy beam to follow the three-dimensional representation of the captured skin area.
