    摘要: A mild hyperthermia treatment apparatus (10) includes an imager (12), which generates a planning image (34) and temperature maps (36) of a target region. An array of ultrasonic transducer drivers (52) individually drives ultrasonic transducers of a phased array of ultrasonic transducers (50). One or more processors or units receive a target temperature profile, and calculate power, frequency, and relative phase for the transducer drivers to drive the phased array of ultrasonic transducers to generate a multi-foci sonication pattern configured to heat the target region with the target temperature profile while limiting peak acoustic pressures. During treatment, the imager generates a series of temperature maps which the one or more processors or units compare with the target temperature profile and, based on the comparison, adjust the power, frequency and relative phase with which the transducer drivers drive the ultrasonic transducers.

    摘要: A medical apparatus (600, 700, 800, 900) comprising a high intensity focused ultrasound system (602) configured for generating focused ultrasonic energy (612) for sonicating within a target volume (620) of a subject (601). The high intensity focused ultrasound comprises an ultrasonic transducer (606) with a controllable focus (618). The apparatus further comprises a memory (634) containing machine executable for controlling the medical apparatus and a processor (628) for executing the instructions. Execution of the instructions causes the processor to cause (100, 200, 300, 400, 502) ultrasonic cavitations at multiple cavitation locations (622, 1002) within the target volume using the high intensity focused ultrasound system. Execution of the instructions further cause the processor to sonicate (102, 206, 306, 402, 504) multiple sonication locations (1004) within the target volume using the high intensity focused ultrasound system. The multiple sonication locations and the multiple cavitation locations are targeted by adjusting the controllable focus.

    摘要: It is an object of the invention to address the above mentioned issues related to image quality and patient positioning. This object is achieved by a mock-up antenna configured to be used during radiation treatment delivery, wherein the radiation treatment is delivered based on a radiation treatment plan and wherein the radiation treatment plan is at least partly based on a planning magnetic resonance image. The mock-up antenna is substantially transparent to radiation and comprises connection means configured to allow a connection between the mock up antenna and a fixation means, which fixation means is configured to fixate a position of the mock-up antenna during radiation treatment and. The mock-up antenna further comprises an inner surface configured to be positioned towards a patient in a way such that is affects a position and/or orientation of the patient during radiation treatment delivery, wherein the inner surface has a shape substantially similar to a shape of a working magnetic resonance imaging antenna used during an acquisition of the planning magnetic resonance image.
