Acquisition method and device of exposure image

Abstract

The invention discloses an acquisition method and an acquisition device of an exposure image. By controlling a bulb tube to transmit X rays, electrical signals, which are outputted by each flat paneldetector after receiving the X rays, are acquired; since a ray projection position of the bulb tube provided by the invention is not bound with any one flat panel detector, a normal exposure image canbe generated in accordance with the output signals of each flat panel detector; and then, on the basis of various grayscale values corresponding to the various exposure images, effective exposure images, which satisfy exposure requirements of a scanned object, can be found out, and subsequently, one of the effective exposure images can be selected out as a final exposure image of the scanned object. Therefore, the problem of the prior art that exposure imaging is achieved based on binding of a ray projection position and a specific flat panel detector can be solved, and an operation in the prior art that it needs to detect whether a current projection position is matched with a used detector or not in advance can be omitted, so that the installation of corresponding detection parts can beavoided, and subsequently, imaging cost can be reduced and the reliability of an imaging system can be improved.

AI Technical Summary

Benefits of technology

This technology allows us to create high quality digital cameras without having extra equipment installed or requiring specialized skillset. By controlling how long it takes before capturing any type of light waves, we generate clear and accurate photographic data even if there are multiple detectors attached around them. Additionally, these systems use only one sensor per pixel instead of two sensors which reduces cost while also ensures reliable performance over time.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to accurately generate images from x-ray tubes without wasting resources when only one type of flat-screen detector is being utilized during medical procedures. Current methods require installation of both the right and incorrect flat-film detector before generating accurate radiographic data. Additionally, these previous solutions were complex with increased costs associated with adding identifiers onto the detachments themselves.
