ABSTRACT:
An object rotating type cone beam radiation CT radiographing device in which a high speed and high sensitivity are obtained with low costs is provided. Thus, a radiation CT device of high performance for vehicle-mounted use and group medical examination can be provided at low costs. In the object rotating type cone beam radiation CT radiographing device, a rotational angle of an object is detected, a signal storage period of a batch-exposure type radiation image sensor panel is controlled on the basis of the rotational angle signal, and a signal storage period of a signal storage type reference signal generator is controlled. There is provided a radiation CT radiographing device in which the object can be photographed at arbitrary resolution during the photographing, a fluctuation of a radiation source during the photographing can be detected without using a special detector and corrected in accordance with its detection amount.
