Radiographic imaging system and collimator unit |
| abstract |
An object of the present invention is to suppress the attenuation of X-rays caused by vignetting and a heel effect caused by a source grid and the enlargement of a focal spot size caused by the arrangement of a filter, thereby improving the image quality of a radiographic imaging system. An extending direction of an X-ray shielding part 19a and an X-ray transmission part 19b of a source grating 19 is made parallel to a rotation axis 43 of a rotary anode 40, and a heel effect is generated in an X-ray shielding part 19a and an X-ray shielding part It is made to be parallel to the extending direction of the line transmission part 19b. As a result, it is possible to prevent the X-rays reduced due to the heel effect from being further reduced due to vignetting by the source grating 19. Since the quality filter 48 is disposed upstream of the source grating 19 in the X-ray irradiation direction, the X-rays disturbed by the quality filter 48 can be reduced in focus by the source grating 19.
