The anode heel affect1. should be considered when the structure of interest is more than 43 inches long.2. is a variation in photon intensity across the exposure field.3. occurs because the heel of the anode absorbs more photons than the toe.4. is best used with the thinner body toward the cathode.

Best practice guidelines for the use of automatic exposure control include all of the following except1. set the optimum kV for the body part.2. set the backup timer to 150% to 200% of the expected manual exposure.3. set the highest mA station for the focal spot size needed.4. wide collimation will ensure IR coverage.
