The central ray is located in the center of the:

Source-to-image distance (SID) is the distance from the:

When the anatomy being imaged is parallel to the image receptor, and the X-ray beam is angled, what type of shape distortion will result?

If the OID is 8 inches and the SID is 72 inches, what is the magnification factor?

A technologist acquires an x-ray of the pelvis using 100 kilovoltage peak (kVp), 10 milliampere-seconds (mAs), 40 inches source-to-image distance (SID), and a no grid. The exposure level is good, but the contrast is too low. If the exam is repeated using a 16:1 grid, what new technique should be employed?

What type of shape distortion is present when there is angulation of an image receptor?

When changing your SID from 72” to 56”

According to the inverse square law, if the source-to-image distance (SID) decreases, the receptor exposure will:

Grid ratio is represented by the formula:

When an air-gap technique is used, the amount of scatter reaching the image receptor is decreased because:
