Embodiment Construction

[0028] figure 1 It is a side sectional view of a radiography device. An X-ray tube 1 generates and emits X-rays 2 which travel in the direction of the body 3 . A part of the X-rays 4 is absorbed by the body, while another part of the rays travels through the body as elementary rays along paths 5 and 6 , and the remaining rays are deflected and travel along path 7 as scattered rays.

[0029] The rays via paths 5, 6 and 7 travel towards the photosensitive sheet 8, where they are absorbed by the intensifying screen 9, which is covered with a photosensitive material which fluoresces in the visible light of a certain wavelength, thus exposing the photosensitive sheet 8 ( X-ray imaging) to obtain latent images.

[0030] When an anti-scatter grid 10 is placed between the body 3 and the photosensitive sheet 8 , the rays in the radiation paths 5 , 6 and 7 pass to the anti-scatter grid 10 in front of the photosensitive sheet 8 . The rays in the radiation path 6 pass through the perme...

Abstract

An anti-scatter x-ray grid for medical diagnostic radiography and a method for fabricating includes a substrate having channels therein of material that is substantially non-absorbent of x-radiation and absorbing material in the channels including material that is substantially absorbent of x-radiation. The substrate preferably comprises material capable of remaining stable at the melting temperature of the absorbing material.

Description

technical field [0001] The present invention relates generally to the field of diagnostic radiography and, more particularly, to an anti-scatter grid capable of obtaining high resolution, high contrast x-ray images and a method of making such a grid. Background technique [0002] During medical diagnostic radiography, X-rays are directed at the patient. Some of the X-rays are absorbed by the patient's body, and the rest of the X-rays pass through the patient's body. This differential absorption of X-rays forms an X-ray image on a photosensitive film. [0003] In X-rays passing through the body, the elementary rays travel unimpeded, straight along the path the X-rays originally emitted from the source. Scattered rays are those portions of rays that pass through the body, are scattered by body organs, and then travel at an angle to the original path. Both fundamental and scattered rays expose the photosensitive film, but the scattered rays, due to their different trajectori...
