<p>PURPOSE:To reduce the artifact and to improve the CT value by newly setting a 2nd picture display area including the whole subject to be photographed and reconstructing the image data on the subject based on the projection data in the area. CONSTITUTION:When an image reconstructing signal is sent, the image reconstructing device reads the collected projection data and preserves it in a memory (101). Then, the preprocessing such as the correction and the normalization of a detecting device is performed by using water phantom data or the like for the image data based on the set FOV (102). The convolution processing is performed for the pre-processed image data (103). Then, reconstruction data is generated by performing the back projection processing (104). The BHC processing is performed for the reconstructed image data to generate the BHC processed image (105). The image data are sent to an image data storage device or to an image display device at the output.</p> |
