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:

As field size increases, the amount of scatter radiation _____________.

With the line-focus principle in mind, which end of the image is slightly sharper than the other?

During successful x-ray production, electrons travel from:

The due dates are located in the “start here” section.

How many unit/regional exams are there? (not counting this quiz)

T/F: Ideally when positioning a patient on a table for a supine chest, the patient’s head should be to the right of the radiographer.
