   What is a radiographic grid?

   • Grids are placed between the patient and the image receptor. Using a grid increases radiographic contrast. Grids are made to match the sizes of the image receptors being used. The grid is constructed of lead strips that are so thin that they are sometimes referred to as lead foil strips.

   How does a grid affect radiographic contrast?

   • The grid absorbs scattered radiation and prevents the scatter from reaching and affecting the image receptor. When a grid is used, radiographic contrast increases. The grid is the primary factor used to decrease scatter and increase contrast. Grids are placed between the patient and the image receptor. Using a grid increases radiographic contrast.

   How do radiographic grids improve image quality?

   • Radiographic grids are used to improve radiographic image quality by absorbing scatter radiation that exits the patient, reducing the amount of scatter reaching the IR. It should be noted that grids do nothing to prevent scatter production; they merely reduce the amount of scatter reaching the IR.

   Why does a radiographer need a grid?

   • This causes less radiation to reach the image receptor and reduces IR exposure. The radiographer needs to increase the exposure factors whenever a grid is being used to maintain the correct IR exposure. Suppose a radiographer takes a radiograph that demonstrates good IR exposure without a grid using 5 mAs and 70 kVp.

   What is a X-ray grid?

   • A grid between the patient and the receptor comprises X-ray-absorbing material (eg, lead) interspaced with low-attenuating material (eg, carbon fiber). The amount of scatter reduction a grid provides is directly proportional to the ratio between the height of the grid and the interspacing, also known as the grid ratio.

   What is a beam-restricting device and a radiographic grid?

   • Therefore the radiographer must act to minimize the amount of scatter radiation produced and reaching the IR. Beam-restricting devices and radiographic grids are tools the radiographer can use to limit the amount of scatter radiation that affects the radiographic image and exposure to the patient or personnel.

   A grid is used to absorb scattered radiation and prevent it from reaching the image receptor. A grid consists of lead strips standing on edge separated by interspaces. The focused grid is the most common pattern. Grid cut-off is the unwanted absorption of primary radiation by the grid.

   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.

   The main purpose for using the scatter grid is to increase the image contrast by reducing the background fog due to scatter. The contrast enhancement factor (k) measures how impactful the grid is at improving the contrast. It is the ratio of image contrast with the grid present to image contrast without the grid.

    Grid Changes. When a grid is used or the grid ratio is changed the goal is to change the amount of scattered radiation on the radiograph and this changes radiographic contrast. Scattered radiation also increases the IR exposure.
