Which of the following represents the correct relationship of the central ray to the anatomical part being imaged?

A type of grid in which the grid lines are situated parallel to the divergent rays of the x-ray beam is termed a:

The minimum kVp that requires use of a grid is:

Which combination of variables will result in a radiograph with the lowest spatial resolution?

If a radiograph is produced using a milliampere (mA) of 400 and 0.05 seconds, how should the exposure time be changed if the mA is decreased to 200?

An x-ray exposure at 50 inches results in a beam intensity of 200 µGy. Estimate the new intensity for a distance of 40 inches.

Which of the following sets of factors would be associated with a radiographic image possessing the greatest amount of focal spot blur?

If the original radiograph has good receptor exposure and the mAs is increased and the kVp is decreased according to the 15% rule, which of these statements is true?1) Receptor exposure increases2) Contrast increases3) Receptor exposure decreases4) Contrast decreases5) Receptor exposure stays the same6) Contrast stays the same
