3 COMPUTED TOMOGRAPHY IMAGE PROCESSING APPARATUS AND METHOD OF GENERATING THREE-DIMENSIONAL RECONSTRUCTED IMAGE

摘要

The present invention relates to a central processing unit for generating a three-dimensional restored image based on a CT (Computed Tomography) photographed image, a temporary restored image, and a temporary comparison image; And a plurality of parallel processing cores, wherein in accordance with the control of the central processing unit, the input image is subjected to projection or inverse projection transformation in parallel on the plurality of parallel processing cores, Wherein the central processing unit controls the programmable logic device to perform a backprojection conversion of the CT photographed image to generate the temporary reconstructed image and to convert the projected reconstructed image into the programmable logic device And controls the logic device to generate the temporal comparison image. According to the present invention, a three-dimensional CT image can be restored in a simple, quick, and low-cost manner by processing a three-dimensional CT image in parallel using a programmable logic device.
