Title:
IMAGING DEVICE USING SLIT SCANNING
Document Type and Number:
WIPO Patent Application WO/2022/156160
Kind Code:
A1
Abstract:
An imaging device using slit scanning, relating to the technical field of digital X-ray imaging methods, comprising: an emitting end (1) for collimating an X-ray into a slit X-ray, continuously emitting the slit X-ray to an object to be imaged, and enabling, in the manner of a line moving to form a plane, said object to be completely captured by the slit X-rays; and a receiving end (2) for, once the slit X-ray emitted each time passes through said object, automatically activating on the receiving end (2) a slit region of interest (ROI 3) corresponding to the emitting direction of the slit X-ray, acquiring attenuated slit X-rays, converting same into slit images having the same range as the capturing range of the slit X-rays and storing same, and splicing the slit images after complete capturing. The present invention collimates an X-ray by means of the manner of slit scanning, avoiding the amplification effect of imaging by a point light source, being applicable to the acquisition of an image of a patient in a real proportion, and allows a patient to be subjected to a radiation dose far lower than the dose of spiral scanning, and is at the level of ordinary radiation.
