摘要:
An ultrasound system employs an ultrasound probe (31), a strain sensor(33) and a workstation (20). The ultrasound probe (31) includes an ultrasound transducer for acquiring ultrasound images (40) of an anatomical region. The strain sensor(33) is arranged on the ultrasound probe (31) to measure a longitudinal strain applied by the anatomical region to the ultrasound probe (31) as the ultrasound transducer acquires ultrasound images (40) of the anatomical region. The strain sensor(33) encircles a longitudinal axis of the ultrasound probe (31) and is spaced from the ultrasound transducers relative to the longitudinal axis of the ultrasound probe (31). The workstation (20) reconstructs an ultrasound volume (41) from the ultrasound images (40) acquired by ultrasound transducer, and responsive to the longitudinal strain measured by strain sensor(33), determines an axial force and/or a bending force applied by the anatomical region to the ultrasound probe (31) as the ultrasound transducer acquires ultrasound images (40) of the anatomical region.

In the method at least one of first and second method steps is performed, where in the first method step at least one mechanical wave is generated by means of electromagnetic waves at at least one generation location into the skeleton (107) through soft tissue (105). In the second method step skeletal vibrations due to at least one mechanical wave are detected by means of electromagnetic waves, they are recorded at at least one recording location to form mechanical wave information, and the distance of said at least one recording location from said at least one generation location is known, and further in the second method step is determined skeletal properties based on at least one recorded signal.

The invention provides for a medical instrument (300, 500, 600) comprising a high intensity focused ultrasound system (302) comprising an ultrasonic transducer (306) with multiple transducer elements (400, 402, 404, 406, 408). The medical instrument further comprises a memory (334) containing machine executable instructions (350, 352, 354, 520, 522, 524) which cause a processor to receive (100, 200) a treatment plan (340) specifying a protected zone (322) within a subject (301) and to calculate (102, 208) a set of transducer control parameters (342) using the treatment plan. The set of transducer control parameters specify the switching of electrical power to the multiple transducer elements. An ultrasonic intensity estimate (900) in the protected zone is below a predetermined threshold. The ultrasonic intensity estimate is calculated using an incoherent sum of the ultrasonic pressure generated by each of the multiple transducer elements.

A method can include targeting a region of interest below a surface of skin, which contains fat lobuli and delivering ultrasound energy to the region of interest. The ultrasound energy generates a conformal lesion with said ultrasound energy on a surface of a fat lobuli. The lesion creates an opening in the surface of the fat lobuli, which allows the draining of a fluid out of the fat lobuli and through the opening. In addition, by applying ultrasound energy to fat cells to increase the temperature to between 43 degrees and 49 degrees, cell apoptosis can be realized, thereby resulting in reduction of fat.

An applicator for providing HIFU therapy to a patient includes a HIFU transducer that is rotatably coupled to a frame. In one embodiment, the rotatable coupling is configured such that the HIFU transducer can be mechanically oriented to position a focal zone of the HIFU transducer at any desired location in a treatment volume radially outward from a longitudinal axis of the applicator while the HIFU transducer remains within a housing that is not more than a defined percentage (e.g., 50%) larger than the maximum diameter of the HIFU transducer. In one embodiment, the HIFU transducer is rotatably coupled to the frame with a ball and socket joint. In another embodiment, the HIFU transducer is rotatably coupled to the frame with an offset gimble assembly. A pair of linear actuators and drive shafts engage the HIFU transducer to orient HIFU transducer in a desired direction.
