Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

The X-ray imaging system generally comprises a vertical acquisition device and a horizontal acquisition device, wherein the vertical acquisition device generally comprises a chest stand and a detector assembly arranged on the chest stand, the horizontal acquisition device generally comprises an examining bed and a detector assembly arranged below the examining bed, and the detector assembly generally comprises a flat panel detector and a grid, wherein the grid is used for filtering scattered rays to improve the detail contrast of an X-ray image, so that the quality of the image can be ensured; the flat panel detector is used for converting X-ray energy into electric signals, and is one of the core components in the X-ray imaging system.

Because vertical collection system and clinostatism collection system all use the detector element, and the price of the flat panel detector in the detection subassembly is expensive relatively, consequently, in order to control the cost of X ray imaging system, often take out detector element from vertical collection system and place in clinostatism collection system, perhaps take out detector element from clinostatism collection system and place in vertical collection system, take out from clinostatism collection system and move other detection rooms with detector element even and be practical. The flat panel detector and the grid are relatively separated, and the detector assembly is quite complicated in the installation process, so that the operation of a doctor is increased, and the detection time of a patient is prolonged.

As shown in fig. 1 to 10, according to a first aspect of the present application, the present application provides an X-ray imaging system, which includes a vertical apparatus 200, a lying apparatus 300, and a receiving apparatus 100, wherein the vertical apparatus 200 includes a lifting column 201, the lying apparatus 300 includes an examining table 301 with a movable bed surface, a support plate is disposed below the bed surface of the examining table 301, and the receiving apparatus 100 includes a grid 20, a flat panel detector 30, a frame structure 10, and a locking structure 40 disposed on the frame structure 10.

To keep costs down, X-ray imaging systems typically have only one flat panel detector, which is often inserted manually into the cassette of the lifting column 201 or the cassette of the examination table 301, depending on the practice, while the flat panel detector 30 is separate from the grid 20, thus increasing the workload of the user.

Specifically, when the flat panel detector 30 is placed on the support plate below the examination table 301, the flat panel detector 30 may be placed on the support plate horizontally according to the shooting requirement, or the flat panel detector 30 may be placed on the support plate vertically, so that the relative position of the flat panel detector 30 on the lifting column 201 or the support plate may be ensured according to the horizontal limiting member 13 and the vertical limiting member 12. As shown in fig. 1 to 10, according to a fourth aspect of the present application, the present application further provides a receiving apparatus for use in an X-ray imaging system, including a grid 20, a flat panel detector 30, a frame structure 10 and a locking structure 40 disposed on the frame structure 10, the grid 20 is disposed on the frame structure 10, the flat panel detector 30 is fixed on the frame structure 10 by the locking structure 40, wherein a horizontal limiting member 13 and a vertical limiting member 12 are disposed on the frame structure 10, so that after the flat panel detector 30 is fixed on the frame structure 10 by the locking structure 40 in a horizontal or vertical direction, the position of the flat panel detector 30 corresponds to the position of the grid 20.

It should be noted that, at present, only one flat panel detector 30 is basically configured in the low-configuration X-ray imaging system, wherein the flat panel detector 30 needs to be moved between the lifting column 201 and the examination couch 301 according to the requirements of clinical photographing. However, in general, a cassette is designed on each of the lifting column 201 and the examination bed 301, and a tray structure similar to a drawer is installed in the cassette, so that the flat panel detector and the grid 20 placed on the frame structure 10 can be placed in the cassette through the tray structure, or the flat panel detector 30 and the grid 20 can be taken out of the cassette, which not only increases the cost of design, but also makes it troublesome to take and place the flat panel detector 30 and the grid 20 through the tray structure. And this application fixes flat panel detector 30 at frame construction 10 through locking structure 40 for flat panel detector 30 and grid 20 can be in the same place through frame construction 10 combination, has so not only reduced doctor's work load, also simplifies flat panel detector and grid simultaneously and places the structure on examining table and lift stand 201, reduction equipment cost.
