ARRT radiology exam WITH CORRECT SOLUTIONS 2023

high kVp / kilovoltage interaction between the x ray photons and matter as illustrated in Figure 4 - 22 is most likely to be associated with picture page 220 The higher the ________the greater the exposure latitude / margin of error in exposure A.kilovoltage range B.mAs range C.grid range A.kilovoltage range Bushong 9th edition page 256 - 257 Higher _______ produces more energetic photons, is more penetrating, and produces more grays on a radiographic image, lengthening the scale of contrasts. A.kilovoltage B.mAs C.grid A.kilovoltage Bushong 9th edition page 256 - 257 As kilovoltage increases, the percentage of scattered radiation also increases A.kilovoltage B.mAs C.grid A.kilovoltage Bushong 9th edition page 256 - 257 Differences inadjacent densities on the image. High _______: Few shades of gray, short scale (low kvp) Low ________: Many shades of gray, long scale (high kvp) Factors affecting: grids, beam restriction, filtration, anatomy, pathology Contrast The active portion of a CR IP is(are): a. Calcium tungstate b. PSP c. Silver bromide crystals d. Rare earth phosphor b. PSP photo stimulated phosphor Mosby's Comprehensive Review of Radiography: The Complete Study Guide and ... By William J. Callaway one of the biggest advantages of CR/DR is the _______ it offers a. latitude b. longitude c. Silver bromide crystals d. Rare earth phosphor a. latitude also known as exposure latitude Shepherd page 332 With CR/DR this affords a much greater exposure latitude and technical inaccuracies can be effectively eliminated. Over exposures of up to _______ percent and under exposures of up to _____ PERCENT are reported as recoverable thus eliminating most retakes A.500 / 80 B. 80 / 80 C.50/50 D.40 / 30 A.500 / 80 percent Shepherd page 332
