ABSTRACT:
An X-ray CT scanner apparatus comprises a rotatable support and a mounting support. The rotatable support holds an X-ray generating source and an X-ray detector in opposition to each other, and is rotated around a patient placed between the X-ray generating source and the X-ray detector. The mounting supporting supports the rotatable support in a rotatable manner. The X-ray CT scanner further comprises an X-ray data collecting unit attached to the rotatable support, a transmission member attached to both the rotatable support and mounting support, and an image-reconstructing circuit. The X-ray data collecting unit includes a data collecting circuit for collecting the X-ray projection data obtained by the X-ray detector when an X-ray CT scan is performed with respect to the patient, and also a buffer for storing the collected X-ray projection data. The transmission member transmits the X-ray projection data from the buffer to the mounting support during a rest time of the X-ray CT scan. By use of this transmitted data, the image reconstructing circuit reconstructs an image of the patient.
