Embodiment Construction

[0108] Elements with like reference numbers in these figures are either equivalent elements or perform the same function. Elements discussed above will not necessarily be discussed in later figures if the elements are functionally equivalent.

[0109] figure 1 An embodiment of the method according to the invention is shown. In step 100, magnetic resonance thermometry data is repeatedly acquired. In step 102, the irradiation volume is heated using a tissue heating system. In step 104, the irradiation volume is irradiated with the radiation therapy system.

[0110] figure 2 A block diagram illustrating another embodiment of the method according to the invention is shown. In step 200, a treatment plan is received. In step 202, magnetic resonance imaging data is acquired. In step 204, the magnetic resonance image data is registered with the treatment plan. Registration of the magnetic resonance image data and the treatment plan establishes a link between the geometry of t...

Abstract

The invention provides for a therapeutic apparatus comprising a tissue heating system (302, 480, 482). The therapeutic apparatus further comprises a magnetic resonance imaging system (300) for acquiring magnetic resonance thermometry data (366) from nuclei of a subject (318) located within an imaging volume (330). The therapeutic apparatus further comprises a radiation therapy system (304, 592) for irradiating an irradiation volume (316, 516) of the subject, wherein the irradiation volume is within the imaging volume. The therapeutic apparatus further comprises a controller (354) for controlling the therapeutic apparatus. The controller is adapted for acquiring (100, 210) magnetic resonance thermometry data repeatedly using the magnetic resonance imaging system. The controller is adapted for heating (102, 208) at least the irradiation volume using the tissue heating system. The heating is controlled using the magnetic resonance thermometry data. The controller is adapted for irradiating (104, 208) the irradiation volume.

Description

technical field [0001] The invention relates to a radiation therapy system, in particular to a radiation therapy system with magnetic resonance guidance. Background technique [0002] In radiation therapy, ionizing radiation is used to selectively destroy areas of tissue in a subject. Radiation therapy is usually used to kill cancerous tumors. Various types of ionizing radiation are available: charged particles, X-rays and gamma rays. [0003] The difficulty with radiation therapy is that ionizing radiation can cause damage to healthy tissue along the path of the ionizing radiation. Accordingly, it would be advantageous to minimize the effects of ionizing radiation on healthy tissue along the path of the ionizing radiation. [0004] US patent application US 2005 / 0080468 discloses that application of ultrasound to an area generates thermal therapy, thereby enhancing the efficiency of radiation therapy. German patent application DE 102007060189 mentions the synergy and app...
