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.

A radiographic image produced showing a small degree of differential attenuation is best descraibed as having a:

Which beam position would produce superimposition of parts A, B and C?

Adjustments in kVp should be used to control radiographic

If an initial exposure is made using 800 mA, 0.02 sec, 16 mAs, 70 kVp, 58” SID, 4 “ OID, 5:1 grid ratio, 0.2 mm focal spot and 3.0 mm of filtration, with a 14 x 17 in field size, and the technologist changes the exposure time to 0.04 sec for a second exposure without changing any other factors, what differences would you expect to see in the second exposure?1) Increased IR exposure2) Decreased IR exposure3) Increased contrast4) Decreased contrast5) Increased spatial resolution6) Decreased spatial resolution7) Increased distortion8) Decreased distortion

The distance between the anatomy being imaged and the focal spot is called:

Calculate the new  mA  required to maintain the same IR exposure produced with the original values.

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

During the exposure, the grid in the bucky:

The central ray is located in the center of the:
