1. A medical high intensity focused ultrasound system comprising:
- a base unit including;
(a) a primary controller having a primary digital interface;
(b) a cooling liquid recirculation circuit; and
(c) a cable carrying an electrical transmission member, an information transmission member, and a plurality of cooling liquid conduits; and
a therapy head including;
(a) a body coupled to the cable;
(b) a secondary controller having a secondary digital interface, the secondary controller coupled to said primary controller by the electrical transmission member and the information transmission member; and
(c) a cartridge removably attached to the body, the cartridge including a sealed enclosure, an acoustic coupling liquid inside the sealed enclosure, and a high intensity focused ultrasound transducer in the acoustic coupling liquid inside the sealed enclosure, the cartridge further including a heat exchanger thermally coupled to draw heat from the acoustic coupling liquid without removing said acoustic coupling liquid from the sealed enclosure, the heat exchanger including a conduit disposed within the sealed enclosure and connected to inlet and outlet ports formed through the wall, the conduit of the heat exchanger coiled to surround a central space defined inside the sealed enclosure, and the inlet port of the conduit configured to receive a cooling liquid from the cooling liquid recirculation circuit via the cooling liquid conduits when the cartridge is attached to the body for circulation through the conduit to cool the acoustic coupling liquid while the acoustic coupling liquid remains isolated from the cooling liquid, and the high intensity ultrasound transducer coupled to the electrical transmission member when the cartridge is attached to the body,wherein the high intensity ultrasound transducer is disposed in the central space, and the acoustic coupling liquid is separated by the heat exchanger from the cooling liquid supplied to the heat exchanger by the cooling liquid conduits.

Abstract
A medical ultrasound system. A base unit is included having system electronics, a user interface and ultrasound control electronics. An ultrasound therapy head is in electronic communication with the base unit. The therapy head includes a replaceable, sealed transducer cartridge with a coupling fluid therein. A cooling system is provided for cooling the coupling fluid. A plurality of guide indicators are positioned around the therapy head to align with crossed lines on a patient so as to properly align the therapy head prior to use. The therapy head can provide variable treatments to an area while the therapy head is in contact with a patient.
