Question

Which does NOT minimize the radiation dose to the patient?

a. decreasing distance from the x-ray tube to the patient
b. filtration of the low energy photons from the beam
c. increasing pitch
d. pre-patient collimation

Answer 1

Decreasing the distance from the x-ray tube to the patient does not minimize the radiation dose to the patient; increasing the distance would reduce the radiation exposure.

Step-by-step explanation:

To minimize radiation dose to the patient, various measures can be taken, such as using shielding, increasing the distance between the source and the patient, filtering low-energy photons from the beam, and pre-patient collimation. In the context of the provided options, the action that does NOT minimize the radiation dose to the patient is a. decreasing distance from the x-ray tube to the patient. On the contrary, increasing the distance would cause the radiation to spread out more and reduce the intensity of exposure, thereby minimizing the dose. Filtration of low-energy photons (b), increasing pitch (c), and pre-patient collimation (d) all serve to reduce the patient's radiation exposure.
