What is grid cutoff, and how can it affect radiographic images?

Grid cutoff refers to a phenomenon in radiography where the lead strips of an anti-scatter grid absorb some of the primary X-ray beam, resulting in reduced image contrast and visibility of anatomical details. This occurs when the X-ray tube is not accurately aligned with the grid, causing some of the primary X-ray photons to be absorbed before reaching the image receptor.

Grid cutoff can affect radiographic images by reducing image contrast, particularly in areas of high subject contrast where scatter radiation is prevalent. This leads to decreased visibility of subtle structures and diagnostic information, potentially compromising the accuracy of the radiological interpretation. Additionally, grid cutoff may result in a mottled appearance or grid lines visible on the image, further degrading image quality. Proper alignment of the X-ray tube, grid, and image receptor, along with regular quality control measures, is essential to minimize grid cutoff and ensure high-quality radiographic images. We are a manufacturer of X-ray machines and their accessories.
