Definitions
- the present invention relates to an X-ray imaging apparatus, and more particularly to a detection module for detecting the X-rays transmitted through the object to be photographed.
- X-ray imaging is being done in a variety of medical fields for testing.
- Scattered radiation results in reduced image contrast and increased noise. Therefore, it is desirable to detect only primary radiation having useful image information.
- an anti-scatter grid is used to transmit the main radiation and block (or attenuate) the scattered radiation.
- Republic of Korea Patent Publication No. 10-2011-0063659 or 10-2011-0089134 discloses a technique applied to the grid in MAMMOGRAPHY.
- Mammography is an X-ray apparatus used to detect breast cancer, lesions and microcalcifications.
- the grid is located between the object to be photographed (eg 'breast') and the detector.
- the grid is then reciprocated to perform its function properly.
- the present invention relates to a reciprocating technique of grids.
- the moving device 143 is required for the reciprocating movement of the grid 141.
- the moving device 143 includes a pair of coupling members 143a and 143b, a guide shaft 143c, a moving source 143d, a pair of compression springs 143f-1 and 143f-2, and a pair of support members 143g. 143h).
- Longer guide holes GH 1 and GH 2 are formed in the coupling members 143a and 143b in the moving direction of the grid 141 (left and right directions, see arrows).
- the front ends of the coupling members 143a and 143b are coupled to the grid 141.
- a coupling groove JS is formed at the rear end of the one side coupling member 143a.
- the guide shaft 143c has a pair of guide rods 143c-1 and 143c-2 that are long in the horizontal direction.
- the guide bars 143c-1 and 143c-2 are inserted into the guide holes GH 1 and GH 2 of the coupling members 143a and 143b. As a result, the left and right movements of the coupling members 143a and 143b are guided by the guide rods 143c-1 and 143c-2.
- the moving source 143d includes a motor 143d-1 and a transmission member 143d-2.
- the motor 143d-1 generates the moving force of the coupling members 143a and 143b. In FIG. 1, the moving force is applied in the left direction.
- the front end is inserted into the coupling groove JS of the coupling member 143a and the rear end of the transmission member 143d-2 is connected to the motor 143d-1 side. Therefore, the transmission member 143d-2 transmits the moving force generated by the motor 143d-1 to the coupling member 143a.
- Compression springs (143f-1, 143f-2) is installed in the form that the guide rods (143c-1, 143c-2) is inserted.
- the compression springs 143f-1 and 143f-2 exert an elastic force on the coupling member 143a in the right direction.
- the support frames 143g and 143h support the bottom of the grid 141.
- the moving force generated by the motor 143d-1 is transmitted to the coupling member 143a through the transmission member 143d-2. Accordingly, the coupling members 143a and 143b and the grid 141 move in the left direction.
- the compression springs 143f-1 and 143f-2 are compressed.
- the coupling members 143a and 143b and the grid 141 move to the right by the elastic restoring force of the compression springs 143f-1 and 143f-2.
- the movement of the grid 141 is preferably made close to the constant velocity.
- the compression springs 143f-1 and 143f-2 have short lengths due to the limitation of installation. As a result, there is a large deviation between the initial restoring force (the restoring force when the compression spring is maximally compressed) and the late restoring force (the point immediately before the grid returns to the original position).
- the front end of the transfer member (143d-2) is inserted into the coupling groove JS of the coupling member (143a) freely. This causes vibration and noise due to backlash between the transmission member 143d-2 and the coupling member 143a at the initial stage of the movement force generation of the motor 143d-1.
- the grid 141 may not move at a constant speed within the moving section (about 12 mm). And when the transmission member 143d-2 strikes the coupling member 143a, vibration and noise are generated.
- the grid 141 may be inclined at an angle according to the photographing angle of the breast.
- the support frames 143g and 143h cannot stably support the grid 141.
- An X-ray imaging apparatus for achieving the above object, the generator for irradiating X-rays to the object to be photographed; And a detection module for detecting X-rays passing through the photographing object.
- the detection module includes a grid for reciprocating first and second positions; A detector for detecting X-rays passing through the grid; And a moving device for reciprocating the grid.
- the moving device includes a moving source providing a moving force for moving the grid from the first position to the second position; And a tension spring for exerting a tension for moving the grid from the second position to the first position. It includes.
- the moving device includes: a coupling member connecting the moving source and the grid to transfer the moving force of the moving source to the grid;
- a guide shaft having a guide portion for reciprocating the coupling member; It further includes,

It further includes.
- the moving device further includes at least one support frame having an insertion groove into which a portion of the grid is inserted to support the grid.
