In an AP chest x-ray, which change would increase image receptor exposure?

In an AP chest x-ray, decreasing the grid ratio increases image receptor exposure. Grids are used to reduce the amount of scatter radiation that reaches the image receptor, but they also absorb some of the primary radiation. A grid with a higher ratio will absorb more primary photons, leading to reduced exposure to the image receptor. By decreasing the grid ratio, there is less absorption of the primary beam, allowing more of the radiation to reach the image receptor, which results in increased exposure and potentially a darker image on the radiograph.

Understanding this concept is crucial for technicians, as adjusting grid ratios can help manage exposure levels based on varying patient conditions or specific imaging requirements. By manipulating these settings, radiologic technologists can optimize image quality while ensuring patient safety through appropriate exposure levels.
