Abstract

PURPOSE: To secure acquisition of a high-quality picture with a reduced number of the detection cell.
CONSTITUTION: X-ray 2 of expansion angle α is turned centering on X-ray generation point 14, and a position matching is given so that side line 13 may pass through central axis 8 of table 5 and side line 12 may touch shooting region 11 respectively. The left half of region 11 is photographed at position 1 where the axial line combining X-ray tube 1 and the center of detector 4 turned by /2 rotation to the center line of table 5 and centering on point 14; while the right half is photographed at position 1" with 180° rotation of tube 1. Thus, the detection cell suffices with a half, and the resolution does not change substantially. And the tomograph of region 11 can be obtained with the same resolution with the number of the detected data is reduced 1/2, thus shortening the data process time.
