Description

A slit scanning device and method for accurate X-ray exposure parameters Technical Field

[0001] The present invention relates to the technical field of X-ray exposure, and in particular to a slit scanning device and method for accurately determining X-ray exposure parameters. Background Art

[0002] Currently, there are two main methods for long bone splicing: one is to stitch the entire image, that is, to take several X-ray images of the full size of the detector and then stitch them together; the other is to use slits for continuous scanning and then stitch each strip of X-ray image together.

[0003] For the second slit shooting method, pre-scan or depth camera are usually used to obtain exposure parameters, but both have certain defects, as follows:

[0004] 1. If a pre-scan is used, a low-dose X-ray exposure of the area to be examined is performed, similar to fluoroscopy, to obtain the corresponding image brightness. The dose for the actual exposure is then inferred from the brightness value. Although this method can provide appropriate exposure parameters for the actual exposure, it requires the patient to undergo an additional pre-scan, increasing the overall exposure dose and being detrimental to the patient's health.

[0005] 2. If a depth camera is used for shooting, although this method can obtain depth information, it requires the patient to be close to the support frame or bed surface. Otherwise, errors will be caused by the gap between the detector and the patient.
