When technical radiographic exposures are to be selected,which of the following are some of the factors that should be considered?
1)Mass per unit volume of tissue of the area of clinical interest
2)Effective atomic numbers and electron densities of the tissue involved
3)Type and quantity of filtration used

Question

Quizplus · Accepted Answer

All three factors mentioned in the question should be considered when selecting technical radiographic exposures. The mass per unit volume of tissue of the area of clinical interest affects the amount of radiation required to produce a diagnostic image. The effective atomic numbers and electron densities of the tissue involved determine the amount of attenuation and scatter of the X-rays. The type and quantity of filtration used affect the quality of the X-rays and reduce patient radiation dose. Therefore, all three factors are important when selecting technical radiographic exposures.
