Problems solved by technology

[0005] Existing X-ray imaging equipment uses line array detectors in the process of collecting projection data, which is time-consuming. At the same time, because the distance between the ray source and the receiver is fixed, when the object to be detected is too small, whether it is a flat film image or CT In the tomographic image, the object only occupies a small part of the image, and most of the other image areas are useless information; when the detected object is too large, whether it is a plain film image or a CT tomographic image, part of the object information will occupy the entire image, other part information of the object will not be available
At the same time, the relative positions of the ray source and the receiver are also fixed, and the DTS imaging function cannot be realized

Abstract

The invention discloses an X-ray imaging device and an imaging method thereof. The X-ray imaging device comprises a base, a slide track is arranged on the base and provided with a first end and a second end, and the upper edge of the slide track is sequentially provided with a ray source control device, a support control device and a receiver control device. The ray source control device comprises a first column, a first pitching motion device and a ray source. The support control device comprises a table top support column and a rotary table top, wherein the table top support column can movably connected to the slide track, and a rotary shaft is arranged in the table top support column. The rotary table top is connected with the rotary shaft and is supported on the table top support column through the rotary shaft. The receiver control device comprises a second column, a second pitching motion device and a receiver. The X-ray imaging device and the imaging method integrates a perspective mode, a cone-beam round track CT mode, a cone-beam a cone-beam track CT mode and a digital theater system DTS mode.

Description

technical field [0001] The invention relates to the field of X-ray imaging, in particular to an X-ray imaging device and an imaging method thereof. Background technique [0002] X-rays have high penetrating power and are widely used in the fields of medical diagnosis and industrial inspection. Common X-ray imaging methods are X-ray and flat film. However, these two imaging methods can only obtain planar images in the projection direction, but cannot obtain depth information along the projection direction, that is, tomographic images. [0003] CT (computed tomography) imaging makes up for the shortcomings of the above two X-ray imaging methods. The X-ray tube and detector can be used to rotate around the detected object synchronously to obtain a sequence of projection images in the 360° range of the detected object. Using the reconstruction algorithm A series of two-dimensional tomographic images of the object can be obtained by processing these images, and these two-dimens...
