What is the effect of proper filtration on patient exposure during x-ray examinations?

Proper filtration in x-ray examinations is designed to enhance image quality while minimizing patient exposure to unnecessary radiation. Filtration works by absorbing low-energy x-rays that do not contribute to the diagnostic value of the images. These low-energy photons can increase the dose received by the patient without enhancing the quality of the diagnostic information obtained.

By removing these low-energy x-rays, proper filtration effectively reduces the overall radiation dose to the patient. This not only safeguards the patient from unnecessary exposure but also helps focus the x-ray beam on the higher-energy photons that are more likely to penetrate tissues and provide clearer images. As a result, the proper use of filtration is integral to maintaining optimal patient safety and ensuring the efficacy of the radiographic process.
