Abstract: A medical imaging system (900, 1000, 1100, 1200) for acquiring medical image data (930), the medical imaging system comprising: a tissue treating system (910, 1080, 1180, 1190, 1280, 1290) for treating a target volume (908); a computer system (918) comprising a processor (922), wherein the computer system is adapted for controlling the medical imaging system; and a memory (928) containing machine readable instructions (954, 956, 958, 962, 964, 966, 968, 970, 972, 974). Execution of the instructions cause the processor to: acquire (100, 200, 308) medical image data; reconstruct (102, 202, 310) a medical image (932) using the medical image data; receive (104, 204, 312) an image segmentation seed (600, 934) derived from a treatment plan (936), and identify (106, 210, 314) a treated volume (400, 700, 800) in the medical image by segmenting the medical image in accordance with the image segmentation seed.

Abstract: A therapeutic apparatus comprising a high intensity focused ultrasound system for treating a target region. The therapeutic apparatus further comprises a display for displaying treatment planning data. The therapeutic apparatus further comprises a memory containing machine executable instructions. The memory further contains a geometric model of the high intensity focused ultrasound system. Execution of the instructions causes a processor to receive the treatment planning data. Execution of the instructions causes the processor to render the geometric representation of the target region from the treatment planning data on the display. Execution of the instructions further causes the processor to calculate an achievable target region using the geometric model. Execution of the instructions further causes the processor to render the achievable target region on the display.

Abstract: 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.

Abstract: A therapeutic apparatus (500) comprising a high intensity focused ultrasound system (100, 200, 504) for treating a target region (526). The therapeutic apparatus further comprises a display (552) for displaying treatment planning data (562). The therapeutic apparatus further comprises a memory (556) containing machine executable instructions (580, 582, 584, 586, 588). The memory further contains a geometric model (572) of the high intensity focused ultrasound system. Execution of the instructions causes a processor (548) to receive (300, 400) the treatment planning data. Execution of the instructions causes the processor to render (302, 402) the geometric representation of the target region from the treatment planning data on the display. Execution of the instructions causes further causes the processor to calculate (304, 404, 406) an achievable target region (593) using the geometric model.
