PURPOSE:To allow the adjustment of a reconstituted image in a short period of time by making pseudo display, in colors, of the image during the course of the reconstitution of the tomographic image and judging whether the reconstitution parameter is inadequate or not by visually emphasizing and viewing the change in the density direction of the image during the course of the reconstitution. CONSTITUTION:The resulted X-ray projected data is subjected to preprocessing including dose correction, gain correction, logarithmic conversion, etc., in a processor 4 for preprocessing of the projected data. The one-dimensional X-ray projected data is superposed with a reconstitution filter function and is reprojected by each piece to a detector position where data by each piece is collected. After one piece or several pieces of the projected data are reprojected, the image during the course of the reprojection is supplied from a processor 5 for reprojecting the projected data to a data conversion processor 7. The image data D during the course of the reprojection is converted to the data to color image in accordance with the color table predetermined in the data conversion processor 7 and is displayed on a color display 8. Whether the parameter is adequate or not is judged by visual observation. |
