IPC: A61B6/03
Filed: 2000-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a X-ray CT device allowing quick measurement of a three-dimensional CT image having a high space resolution in a slicing direction. SOLUTION: X-ray generation points S from a X-ray tube 1 are arranged at plural points Sa, Sb in the direction of the axis Z of rotation of a rotary plate 7 and a multislicing X-ray detector 6 is opposed to each of the plurality of X-ray generation points Sa, Sb. The X-ray tube 1 and the X-ray detectors 6 are mounted on the rotary plate 7 in above positioned relationship and rotated around a subject 9 with the rotation of the rotary plate 7 around the Z-axis. With the relative movement of a bed top plate 4 on which the subject 9 is put and the rotary plate 7 to the Z-axis direction at the same time, the spiral scanning of the subject 9 is carried out by a X-ray from the X-ray tube 1.  The number of total stages of the X-ray detectors can be increased while the apparent angles of the X-ray detectors to the individual X-ray generation points is kept smaller, permitting quick measurement of the three-dimensional CT image having a high space resolution in the direction of the body axis of the subject This results in improved picture quality of the three-dimensional CT image and helps early detection of an initial cancer having a small concentration difference and a volume.
