Question

For an X-ray machine with a kVp lower than 70, what is the purpose of the filtration?

A) Improve image contrast
B) Increase radiation intensity
C) Reduce patient exposure
D) Enhance spatial resolution

Answer 1

Filtration in an X-ray machine with a kVp lower than 70 is used to reduce patient exposure to unnecessary radiation, enhancing safety.

Step-by-step explanation:

For an X-ray machine with a kVp lower than 70, the purpose of filtration is to reduce patient exposure to unnecessary radiation. Filtration absorbs lower-energy X-ray photons that are unlikely to contribute to the image quality but would increase the radiation dose to the patient. By filtering these photons out, the patient is exposed to fewer harmful X-rays, thus enhancing their safety without compromising the diagnostic value of the X-ray procedure. Filtration involves the use of materials to absorb or remove low-energy photons from the X-ray beam before it reaches the patient. This helps to remove unnecessary radiation that could potentially harm the patient. By reducing patient exposure, filtration ensures that the X-ray procedure is as safe as possible.
