With an SID of 40 inches, and an OID of 10 inches, what is the factor of magnification? (round to the nearest answer)

The size of the effective focal spot is controlled by all of the following except:

A radiographer realizes magnification occurred on the radiograph. What is something the radiographer can do to minimize the effects of magnification?

The anode disc slows down or breaks by spinning in reverse after exposure.

What x-ray interaction within the patient produces no scatter radiation, and therefore leave a microscopic “white” spot wherever it occurs in the resulting image:

Foreshortening is a form of:

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)

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?

A decrease in scatter radiation has what effect on subject contrast?

Small focal spots are utilized until the mA station is set above:
