Embodiment Construction

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] Please refer to figure 1 As shown, the X-ray emitted from the focal point A of the CT tube passes through the collimation hole 2 of the front collimator 1 and then projects onto the detector 3. The result of the X-ray projected on the detector 3 is divided into a penumbra 4 and umbra 5. The penumbra 4 is located on the periphery of the umbra 5 . The X-ray dose in the penumbra 4 is less and weaker than that in the umbra 5 . The umbra region 5 can generate a false-free image, and its image quality is clearer and more complete than that of the penumbra regio...

Abstract

The invention relates to a detector device with Z-axis focus tracking and correction capabilities and its use method, including an X-ray emission source, a front collimator and a detector. A collimation hole is arranged on the front collimator, and the front collimator The collimator is also equipped with a tracking hole that can pass through X-rays. The tracking hole is symmetrical to the symmetry line of the collimation hole, and the side of the tracking hole and the collimation hole are connected to each other; area, the lower reference channel area and the reference channel area, the ideal attention channel area receives the X-ray after passing through the collimation hole, the lower reference channel area is located on the lower side of the reference channel area, and the upper and lower reference channel areas and the reference channel area are used to receive X-rays through the trace hole. The invention makes Z-axis focus tracking and correction more simple and convenient, effectively reduces costs and improves economic benefits.

Description

technical field [0001] The invention mainly belongs to the technical field of medical imaging, and in particular relates to a detector device with Z-axis focus tracking and correction capabilities and a use method thereof. Background technique [0002] Digital imaging systems can be used to take images to help doctors make a correct diagnosis. A digital radiography imaging system typically includes a source and a detector. Energy generated by a source, such as X-rays, passes through the object to be imaged and is detected by a detector. An associated control system acquires image data from the detector and modulates a corresponding diagnostic image on the display. One or more collimators may be used to block and / or confine X-rays or other energy from the detector. For example, an opening may be provided in the collimator through which X-rays pass from the source to the detector. [0003] The CT detector system uses the aforementioned principles to work. At present, the ...
