Abstract
Due to the heterogeneous nature of x-rays, metal filters were created to block the lower energy x-ray photons from reaching the image receptor and interfering with the quality of the image. Filters provided the ability to attenuate the lower energy x-ray photons, therefore leaving only the high energy photons to pass through and eventually reach the image receptor to create more diagnostic images with less unpurposeful artifacts, known as image noise. A research experiment was conducted at a forty-six bed hospital located in the Pacific Northwest to visualize how filtration affects image quality, radiation dose to the patient, and how much radiation actually reached the image receptor. In this experiment, inherent filtration and added filtration were tested by taking several images and also incorporating varying thicknesses of aluminum (Al) and copper (Cu).
