Scanning type beam limiting collimation mechanism of X ray source, and control method of scanning type beam limiting collimation mechanism of X ray source

Abstract

The invention relates to the field of X ray shooting equipment, in particular to a scanning type beam limiting collimation mechanism of an X ray source, and a scanning control method of the scanning type beam limiting collimation mechanism of an X ray source. The technical scheme adopted by the invention lies in that the scanning type beam limiting collimation mechanism of an X ray source comprises a scanning collimation block, a scanning direction limiting block and a scanning drive device, wherein the scanning collimation block is driven by the scanning drive device to move in a manner of sticking the upper surface of the scanning direction limiting block in the direction from a first scanning limiting block to a second scanning limiting block. The scanning type beam limiting collimationmechanism of an X ray source disclosed by the invention has the advantages that through driving the scanning collimation block having a unit light field passage in the middle to move for scanning onthe upper surface of the scanning direction limiting block having an effective light field opening in the middle, besides, through cooperation with a lateral limiting block, scattered X rays are shielded and absorbed by the scanning collimation block, the scanning direction limiting block and the lateral limiting block, so that instantaneous radiation dosage and total radiation dosage of environment are reduced, medical personnel and shot people are protected, and image quality is increased.

AI Technical Summary

Benefits of technology

This technology helps reduce patient exposure during x ray imagery while still allowing for accurate detection of specific areas within an object's body without overexposing them or causing damage. By moving the scanner blocks upwardly towards certain parts of interest on top of it, X-radiation cannot pass through but instead focuses onto these sections where there may have been any harm caused due to scatterings. These techniques help minimizing environmental impact and improving image clarity.

Problems solved by technology

This patented technical problem addressed during this patents describes how traditional methods for controlling the amount or intensity (X) of x-radiation used on an imaging device can lead to contamination from unwanted particles that scatter through other parts of its structure.
