X-ray CT equipment

The invention relates to X-ray CT equipment and realizes economical X-ray CT equipment with a large scanning FOV (Field of View) and X-ray CT equipment for simultaneously realizing large scanning FOV and low exposure. The X-ray CT equipment comprises an X-ray radiator, a multichannel X-ray detector, a transmission X-ray data acquiring device, a scanning control device and an image reconstructing device, wherein the X-ray radiator radiates fanned beam X-rays; the multichannel X-ray detector is opposite to the X-ray radiator; the transmission X-ray data acquiring device scans an object when the X-ray radiator and the X-ray detector rotate so as to acquire the transmission X-ray data of two or more visual angles; the scanning control device controls the scanning; and the image reconstructing device reconstructs an image. The fanned beam X-rays radiated by the X-ray radiator are deflected to one side of a rotating center, and the X-ray detector is provided with a plurality of channels of the fanned beam X-rays which are correspondingly expanded; and the scanning control device allows the X-ray radiator and the X-ray detector to scan by rotating at least one circle.
