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?

The normal diagnostic x-ray tube has a filtration equivalency of about 0.5 mm aluminum equivalent. This is called:

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

If an optimal radiograph is acquired at 72 inches with an air kerma of 4 mGy, what will the air kerma be if the distance is reduced to 40 inches?

Which type of grid pattern will result in a radiograph with the least amount of primary beam cutoff?

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

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

Technical factors that are considered “geometric” include                           1. focal spot selection                           2. SID                           3. grid ratio                           4. filtration thickness                           5. OID                           6. tube angulation                           7. part thickness                           8. receptor resolution

The most easily adjusted radiographic beam-restricting device is the:

If an x-ray beam has an intensity of 1.2 mGy at 60 inches, what is the intensity of the beam 40 inches?
