What is a grid? What is the role of the grid for the chest holder? Is the grid necessary?
The grid is mainly used to filter the scattered lines, and the grid is an attachment to the chest holder.
The grid is used for the chest frame and placed in front of the camera frame to absorb and filter the scattered rays on the chest frame to improve the contrast of the X–ray image and make the captured image clearer. The grid is arranged by the X–ray-absorbing lead strip and the permeable X–ray material according to a certain format, and the orientation of the vertical axis of the lead strip in the grid is the grid shape of the grid. According to the geometric classification, the grid can be divided into a parallel grid and a focus grid. There are many types of chest racks, some can be placed in the grid, and some can not be placed in the grid. For example, the chest rack for DR can not be placed in the grid. After using DR, the image clarity can be satisfied. The effect is that you don’t need to use a grid for the chest holder.
