1. a kind of therapeutic equipment (500,600), comprising:

  • For disposing the radiotherapy equipment (502) of the target area (318,536) of subject (316,526), wherein described to putPenetrating therapeutic equipment includes for electromagnetic radiation (310,312,314,508) to be introduced into the brachytherapy sources in the target area(300,302,304,504);

    For from the magnetic resonance imaging system of imaging area (534) gathering magnetic resonance imaging data (624) (510,532,544,602), wherein the target area is within the imaging area, wherein the magnetic resonance imaging system includes for describedThe magnet (510) in magnetic field is generated within imaging area, wherein the radiotherapy equipment is suitable for making the brachytherapy sources at least portionIt point is rotated around the magnet, wherein removing radio frequency body coil from the magnetic resonance imaging system, allow will be described to createTarget area is moved to the space at the rotary shaft of the brachytherapy sources, and the magnetic resonance imaging system further includes that radio frequency is receivedIt sends out device (532), the RF transceiver is positioned to avoid the path of the radiation generated by the brachytherapy sources and be suitable forFrom at least two transmittings and receives channel (528,530) while acquiring MR data;

    For controlling the processor (614) of the therapeutic equipment;

    Memory comprising the machine-executable instruction (636,638,640,642,644) for being executed by the processor(620), wherein the execution of described instruction performs the following operations the processor;

    (100,200) described at least two transmitting is executed using the magnetic resonance imaging system and receives the prescan school of channelQuasi- (634);

    (102,202) described magnetic resonance is acquired according to the pre-scan calibration using at least two transmitting and reception channelData;

    (104,204) magnetic resonance image (626) is rebuild from the MR data;

    It is registrated the position (628) of target area described in (106,206) described magnetic resonance image;

    And(108,208) radiotherapy control signal (630) is generated according to the position of the target area,Wherein, the radiotherapy control signal irradiates the brachytherapy sources to the target area;

    And- Xiang Suoshu radiotherapy system sends (110,212) described radiotherapy and controls signal.
