Abstract
A CT pilot image acquisition method and a CT device are provided. The method may include: performing a helical scan on a predetermined area to be scanned, so as to obtain scanning data; reconstructing a tomographic image based on the scanning data; performing, at a predetermined positioning angle, a parallel beam projection on the tomographic image by using a virtual parallel X-ray beam, so as to obtain projection data; and re-binning a CT pilot image at the predetermined positioning angle based on the projection data. Parallel beam projection is adopted to process the tomographic image, to obtain a pilot image without geometric distortions. The obtained pilot image can reflect an anatomical structure of human body accurately.
