If a grid is made to match the size of a 14 x 17 inch image receptor, the surface of the grid that measures 14 x 17 is called the face of the grid. A line, called the center line, is usually drawn on the face of the grid, which lets the radiographer know the direction of the grid lines, since they are hidden by the grid’s cover.
On the basis of not deviating from the center line of the X-ray grid, the X-ray center line can be inclined at a certain angle according to the inclination direction of the lead rod, so that the X-ray radiation direction is consistent with the lead.
The purpose of a grid in radiography is to _______________. height of the lead strips to the distance between them. grid ratio is defined as the ratio of the _______________. allow more transmitted photons to reach the image receptor. compared with parallel grids, focused grids _______________. linear focused.
Aug 15, 2024 · postero-anterior (PA): central ray passes, perpendicular to the coronal plane, from posterior to anterior depending on the anatomic segment to radiograph, synonyms can be used, for example: occipito-frontal (skull); dorso-ventral (thorax); dorso-palmar (hand)
Sep 21, 2022 · X-ray grids are devices used in radiography to improve the quality of images by reducing the amount of scattered radiation that reaches the X-ray detector or film. The basic purpose of X-ray grid use is to enhance the contrast and quality of the medial image by removing the scatter radiation.
Antiscatter grids improve the X-ray image contrast at a cost of patient radiation doses. The choice of appropriate grid or its removal requires a good knowledge of grid characteristics, especially for pediatric digital imaging. The aim of this work ...

tangential: central ray is directed along the surface of the bone to image adjacent soft tissue e.g. tangential skull soft tissue x-ray for foreign body. en-face: used in imaging foreign bodies, the central ray follows the trajectory of the foreign body to discern soft tissue versus bony involvement.
