Document Summary
The process by which a beam of x-ray photons is altered as it passes through matter is known as: density, attenuation, fog, processing. Computed radiography uses which of the following as its image receptor: photostimuable phosphor plate, direct conversion hard-wired plate, radiographic film, all of the above. The chief controlling factore of radiographic contrast in film/screen radiography is: milliampere seconds (mas, source-to-image distance (sid, object-to-image distance (oid) Which of the following image receptor systems does not use light during exposure: direct conversion dr, indirect conversion dr, computed radiography, film/screen radiography. A radiograph is made using 40 mas at a 40 inch sid. If the image must be repeated at a 72 inch sid, what mas value is necessary to maintain the same exposure: 12 mas, 13 mas, 120 mas, 130 mas. The 15% rule helps explain the effect of _________ on exposure: grids, mas, sid, kilovoltage peak.
