During an x-ray procedure, a technologist receives a dose of 5 micro-Sieverts at a distance of 10 feet from the x-ray source. At a distance of 15 feet, the technologists dose would have been:

Which beam position would produce superimposition of parts A, B and C?

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
