Abstract

PURPOSE: To obtain an image with a larger reconstruction matrix at a lower cost by synthesizing and reconstructing a total image on a display memory, after an image is reconstructed partially on an image memory.
CONSTITUTION: An image data of a patient photographed with an X-ray CT device or the like is collected and a part thereof, for example, a 1/4 image is reconstructed with a matrix of 512 lines x 512 columns in pixel on an image memory 10 within an image reconstructing device. Four images reconstructed in terms of parts are synthesized and reconstructed to a total image on a display memory 20 of a main memory or a frame memory, with a matrix of 1024 lines x 1024 columns in pixel, by controlling an address of the memory to be projected onto a display monitor of a CRT or the like. Thus, an image with a larger image matrix is obtained with a limited capacity of the image memory, thereby enabling the obtaining of a high performance reconstructing device at a lower cost without need for a large capacity of image memories.
