What is the grid density parameter of the grid equipped with bucky stand? Usually, the bucky stand is now used to place flat panel detectors. If it is a grid configured for flat panel detectors, then only conventional parameters are required. For example: 18*18 inches, 10:1, 40L/cm, 1.8m
A brief introduction to the grid: the grid should be placed between the human body and the film, it can filter most of the scattered rays, only a small part of the scattered rays leak.
The structure of the grid and the specifications of the grid: The grid has the following three main technical parameters:
Focal length: the vertical distance from the convergence line of the lead strip to the surface of the grid, f
Grid ratio: It is also a grid ratio, which is the ratio of the lead bar height to the lead bar gap, R
Grid density: the number of lead bars within a unit distance, N
