The typical range of anode bevel angles for general purpose diagnostic x-ray tubes is:

An AP chest x-ray was taken using 5 mAs at 65 inches.  The radiographer is repeating the chest x-ray at 72 inches.  What will the new mAs need to be to maintain the same receptor exposure? (round to the nearest answer)

The focal spot size at the anode was 1.5mm in the x-ray tube used by the radiographer.  The radiographer decided to use 300mA to control motion.  The radiographer used a 45″ SID with an OID of 5 inches.  What will the unsharpness be? (round to the nearest answer)

Foreshortening is a form of:

An increase in focal spot size will ultimately _________ penumbra.

A preliminary radiograph of the gall bladder is taken of the right upper quadrant on an 10×12 inch FOV using 20 mAs and 70 kVp.  The radiologist requests a KUB on a 14×17 inch FOV because he or she thinks the patient might have an early bowel obstruction and he or she needs to see the whole abdomen.  What new mAs is required?

The mirror in the collimator must be mounted at precisely _____ degrees from the light source to the side of the collimator.

The atomic number of barium is ________.

T/F: PBL was found to save patient dose as it eliminated technologists from having to collimate.

The atomic number of iodine is ________.
