A radiograph is acquired with a source-to-skin distance (SSD) of 50 inches. If the radiograph is repeated using the same exposure factors, but the SSD decreases to 35 inches, the patient’s dose will:

Ten kVp is considered a 15% change in which of these kVp ranges?

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.

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.
