Patent Images

1. , a kind of imaging system that is used in the proton beam therapy system, it comprises the beam emission system of a neutron source and a band nozzle, described nozzle is installed on the door frame, make that described proton beam can be from a series of angle directive patients, wherein, the standard indicating image in the zone that the described proton beam therapy reception patient of system will be treated, described imaging system comprises:

  • An imaging beam source that is installed on the described beam emission system, wherein, described imaging beam source can be movable between a primary importance and second position, in described primary importance, described imaging beam source is along the first side emission imaging beam of a treatment course of the beam to described patient, in the described second position, described imaging beam source is removed from described course of the beam, so that allow described proton beam to pass through from described treatment path;

    An imaging beam receiving system, it is installed on the described door frame, so that described receiving system can align the center of course of the beam in any angle of door frame orientation, wherein, described receiving system receives described imaging beam after described imaging beam passes zone on the described course of the beam of being positioned at of patient;

    The image capture device of a described receiving system of next-door neighbour, wherein, described image capture device receives the signal from described receiving system, generates patient'"'"'s directional images in the zone on the inherent described course of the beam of patient'"'"'s body;

    WithA control appliance, be used for receiving described standard indicating image and described patient'"'"'s directional images, wherein, described control appliance so designs, make and on described standard indicating image, to specify one or several rigid structures, to measure the isocenter that to treat in patient'"'"'s body relative position with respect to described one or more rigid structures, the design of wherein said control appliance also makes can specify one or several rigid structures on described patient'"'"'s directional images, so that described control appliance can be measured the relative position of described course of the beam center with respect to described one or more rigid structures, wherein, described control appliance utilizes described target isocenter and described course of the beam center to determine described patient and the required relative motion of carrying out of described door frame with respect to the relative position of described one or more rigid structures, so that described course of the beam center is with respect to the position of described one or more rigid structures, corresponding to the position of described target isocenter with respect to described one or more rigid structures.
