PROBLEM TO BE SOLVED: To simultaneously obtain plural sheets of different image reconstitution condition such as a wide visual field image and a narrow visual field image. SOLUTION: After preparing difference raw date from raw data read from a raw data memory, an image reconstituting part takes the convolution of difference raw data weighted by a cos term and two kinds of reconstitution function by a convolution processing part 213 and applies back projection processing to obtained two kinds of convolution data by a back projection processing part 214 to prepare the wide visual field image 1 and the narrow visual field image 2, etc., to store this in an image memory. After then, the image reconstituting part sends the images 1 and 2 to a display part 22 to simultaneously display on a screen. |
