Title:
X-RAY COMPUTED TOMOGRAPHY (CT) DEVICE, IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2015/016328
Kind Code:
A1
Abstract:
In the present invention, an x-ray CT device is provided with a data collection unit (5) and a reconstruction unit (6). The data collection unit (5) collects first projection data in first pixels arrayed in a prescribed direction in an x-ray detector, on the basis of the output signals of the x-ray detector which detects x-rays that were emitted from an x-ray tube and passed through a subject. The reconstruction unit (6) generates intermediate image data by reconstructing the first projection data, and generates medical image data by reconstructing second projection data acquired on the basis of the projection results of sequential projection of intermediate image data with respect to second pixels the number of which is increased in at least a portion of pixel gaps of the first pixels.
