Chengdu customer calls to consult the x ray grid

Hello friends, I recently called a customer from Chengdu to consult our x ray grid, saying that I do n’t know how to use it after purchase, so today we will take a look at the relevant knowledge about the grid. The improper operation of the friends in the use and placement of the wire grid can not play a very good effect.
The placement of the filter grid; when placing the filter grid, pay attention to the focus surface placed in the direction of the X-ray, and placed in the incident direction of the human body and the X-ray. In order to allow the original emission line to pass through the filter grid the maximum amount, During exposure, the X-ray centerline can be tilted toward the lead bar and can not deviate from the centerline of the grid, so that the X-ray radiation direction and the lead bar direction can be on the same horizontal line to pass the original emission line to the greatest extent, and because The directions of the scattered rays are different and chaotic, so they can absorb the scattered rays and improve the image quality. Therefore, photography has moved out of a concept here. The absorption phenomenon of the original emission line by the filter grid is called the cutting effect. In summary, the reason for the cutting effect is the placement of the filter grid, and the inversion has a tilt angle. It may all happen, the X-ray focus does not coincide with the convergence line and other reasons.
