A
Filtration affects the primary beam in the following way:
(B) Filtration decreases the average energy of the primary beam.
When filtration is applied, it helps to remove the lower energy photons from the primary beam, thereby reducing the average energy of the beam. This is done to improve the quality of the beam by reducing the amount of scatter and increasing the contrast in the resulting image.
As a result of the decrease in the average energy of the primary beam, the intensity of the X-ray beam is also decreased. However, this reduction in intensity is compensated for by increasing the exposure or mAs (milliamperes per second) to maintain the same level of radiation dose to the patient.
Overall, the use of filtration is essential in producing high-quality X-ray images while minimizing the exposure of patients to unnecessary ionizing radiation.
