摘要： PURPOSE: To provide an X-ray CT device by which an X-ray CT image can be obtained even in a condition where various appliances are installed on a patient for a treatment in an IVR treatment. CONSTITUTION: A semicircular arc-shaped detector 4 is mechanically separated from an X-ray source 3, and is suspended from the ceiling by a support mechanism 6, and can be positioned in a prescribed image pickup position from above a patient 1 by extending and contracting the support mechanism 6. The X-ray source 3 is driven while moving it on a circular orbit with the patient 1 as the center by a support mechanism 5, and an X-ray 7 is scanned in a desired scanning range by this. A C-arm and a link mechanism can be adopted as the mechanism 5 to move the X-ray source 3 along the circular orbit. Therefore, positional accuracy necessary for a treatment can be improved.

摘要： PURPOSE:To concentrate the X-ray irradiation to a focus part by memorizing the displacement, quantity of a variable collimator for the revolution angle of a gantry so that the X-ray can be irradiated at a target position, allowing the focus part to coincide with a target position and displacement-controlling the variable collimator according to the memory contents. CONSTITUTION:A RAM 16 stores the displacement quantity of a variable collimator 9 for the revolution angle of a gantry 1 for each calculated prescribed pitch angle of a therapeutic board, in correspondence with the displacement quantity DELTAX and DELTAY of the angle alpha of the therapeutic board and the turning angle 8. A fine movable board 11 is demounted from the therapeutic board 5, and a patient 4 who is positioned so that the center of a focus is positioned at a target position is placed on the fine movable board 11, and the spot shaped X-rays 8 are irradiated to start therapy. In the therapy, the therapeutic board 5 is stopped at each pitch angle, and the during this stop, the gantry 1 is turned around the horizontal axis line on the periphery of the therapeutic board 5. During the revolution of the gantry 1, the variable collimator 9 is angularly controlled according to the accommodated contents of the RAM. Accordingly, the X-ray is directed towards the center of the focus part.

摘要： PROBLEM TO BE SOLVED: To secure safety of treatment by turning off a synchronization signal when an abnormal waveform is detected from respiration information at the treatment in an abnormal judgment module of an analysis module in respiration synchronizer used for treatment of percussion wave such as lithodialysis. SOLUTION: A threshold value that a period moving from exhalation to inhalation is set by the starting point of a stationary period when organ movement is slow is made as a treatable range, and radiation treatment, for example is given to a patient 1. The treatable range is set in a treatment planning device 4 by a diagnostic image 14 from an image diagnosis device 2 and respiration information 15 from the respiration information obtaining means 3, and a treatment plan 16 is output from the device 4 to a respiration synchronizer 5 and a treatment device control unit 6. And when an abnormal waveform is detected from the respiration information in an abnormal judgement module in an analysis module of the respiration synchronization device, the synchronization signal is turned off and treatment is stopped.

摘要： PROBLEM TO BE SOLVED: To realize irradiation with a suited X-ray dosage by suppressing the unnecessary exposure of an examinee to X-rays. SOLUTION: A model M showing a relation between the rotation angle of a CT scanner 102 and an X-ray transmission length concerning the examinee is stored in a memory previously. In CT scanning measurement with respect to the examinee, the examinee is irradiated with X-rays, which is generated by a set tube current at each rotation angle of the scanner 102 fixed by this model M, to perform CT scanning measurement. In this case, the model M shows a relation between the rotation angle of the scanner and the X-ray transmission length, which is obtained by changing the X-ray transmission length to what consisting of water having the same quality as that of a living body and uniform material such as polyethylene. The model is obtained by previous scannogram photographing or a low dosage CT scan.

摘要： PROBLEM TO BE SOLVED: To check whether a beam is irradiation applied accurately or not during treatment by arranging a case body, which is supported on a gantry so as to be freely driven parallelly on the plane vertical to a radioactive beam, and arranging an image signal measurement means, which detects the radioactive beam so as to covert it into an image signal, in the case body. SOLUTION: In radiotherapy, a gentry 5 and a treatment table 6 are driven on the basis of control data stored in a main storage device 3, and the stored irradiation field is set by means of a collimator inside a gantry head. Subsequently, an acceleration device 7 is controlled so as to perform irradiation of radioactive rays, while an irradiation field collation device image signal is measured by means of an image signal measurement unit 42, and the signal is processed into a digital signal so as to be stored in an image storage unit 431. The position, the shape and the dimension of the irradiated field are measured from the digital signal so as to be compared with that in a planning time, and the collimator is controlled so that both of them coincide with each other. If a difference between them is the predetermined value or more, irradiation of radioactive rays is stopped.
