Method and system for ultrasound treatment of fat

A method to treat fat, comprising:

• identifying a plurality of fat lobuli in a region of interest;
• using an ultrasound device to emit ultrasound energy from a therapy element housed within an ultrasound probe to the region of interest at a depth under a skin surface, the region of interest comprising the plurality of fat lobuli and a portion of at least one of an epidermis, a dermis, and a muscle,
• wherein emitting ultrasound energy ablates the plurality of fat lobuli and at least one of the dermis and the muscle under the skin surface;
• and
• moving a motion mechanism operably connected to the therapy element within the ultrasound probe for controllably creating a plurality of thermal lesions to ablate the plurality of fat lobuli and at least one of the dermis and the muscle at the depth under the skin surface,
• wherein the motion mechanism comprises at least one of the group consisting of an encoder and a position device;
• wherein the motion mechanism is controlled by a control system in communication with the ultrasound probe.

A method for non-invasive fat therapy, comprising:

• identifying a plurality of fat lobuli in a treatment region;
• imaging the treatment region comprising the plurality of fat lobuli and a portion of at least one of an epidermis, a dermis, and a muscle;
• focusing therapeutic ultrasound energy from a transducer to form a thermal lesion in the plurality of fat lobuli,
• wherein the therapeutic ultrasound energy ablates the plurality of fat lobuli and at least one of the dermis and the muscle,
• wherein the transducer is housed within an ultrasound probe;
• and
• moving a motion driver operably connected to the transducer within the ultrasound probe for controllably creating a plurality of thermal lesions to ablate the plurality of fat lobuli and at least one of the dermis and the muscle at the treatment region,
• wherein the motion driver is controlled by a control system in communication with the ultrasound probe, wherein the control system controls at least one of a spatial parameter and a temporal parameter.
