Question

Beam Modification with filters uses attenuating material between the tube and the patient, and filtration works by increasing patient exposure by removing low-energy, non-diagnostic photons.

a) True
b) False

Answer 1

False, beam modification with filters uses filtration to remove low-energy, non-diagnostic photons. Filters selectively remove these photons, increasing the patient's exposure to higher-energy, diagnostic photons. To limit radiation doses, shielding, distance from the source, and exposure time are utilized.

Step-by-step explanation:

False, beam modification with filters does not use attenuating material between the tube and the patient. Rather, it uses filtration to remove low-energy, non-diagnostic photons. Filtered beams help reduce patient exposure to unnecessary radiation by removing photons that would not contribute to the diagnostic information.

Filters can be made from materials that selectively absorb or remove specific photons, thereby altering the quality and intensity of the X-ray beam. By selectively removing low-energy photons, filters increase the patient's exposure to higher-energy, diagnostic photons.

To physically limit radiation doses, shielding, increasing the distance from the source, and limiting the time of exposure are used. Shielding absorbs radiation, and the greater the distance from the source, the more the radiation spreads out. Additionally, reducing exposure time decreases the dose received by the person.
