摘要： A high-intensity focused ultrasound (HIFU) therapy system comprises an ultrasound transduce to emit a focused ultrasound beam along a beam path. An ultrasound transparent window is positioned in the beam path. A fluid cooling system to provide cooling of an object to which the focused ultrasound beam is directed. The fluid cooling system includes a fluid receptacle mounted adjacent to the ultrasound transparent window and a cooling unit to cool a coolant and pass the coolant trough the fluid receptacle to and from the fluid receptacle. A degassing module and preferably also a filter to remove volatile components from the coolant. Dissolved air or other gases are removed from the coolant, so that the formation of bubbles in the coolant is avoided or at least suppressed.

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.
