Is hya hyprocess hywhereby hysome hyof hythe hyx-
ray hybeam hyis hyabsorbed hyin hythe hytissue hyand hysome hypassesFthrough hy(transmits) hythe hyanatomic
hypart hy- hyCORRECT hyANSWER hy-differential hyabsorption
The hyterm hydifferential hyis hyused hybecause hyvarying hyanatomic hyparts hydo hynot hyabsorb hythe hyprimary hybeam
hyto hythe hysam hye hydegree
Ex. hyBone hyabsorbs hymore hyx-ray hythan hyair
T hyor hyf hy- hyCORRECT hyANSWERF-True
Creating hya hyradiographic hyimage hyby hydifferential hyabsorption hyrequires hyseveral hyprocesses hyto
hyoccur hy(3) hy- hyCORRECT hyANSWER hy-• hyBEAM hyATTENUATION
• ABSORPTION
• TRANSMISSION
• Primary hyx-ray hyloses hysome hyof hyits hyenergy hy(intensity) hybeam hyas hyit hypasses hythrough hyanatomic hytissue
• Fewer hyx-ray hyphotons hyremain hyin hythe hybeam hyafter hyitFinteracts hywith hyanatomicFtissue.
• result hyof hythe hyphoton hyinteractions hywith hythe hyatomic hystructuresFthat hycomprise hythe
hytissues. hy- hyCORRECT hyANSWER hy-Beam hyattenuation
The hyreduction hyin hythe hyintensity hyor hynumber hyof hyphotons hyin hythe hyprimary hyx-ray hybeam hyis
hyknown hyas hy .
hy- hyCORRECT hyANSWER hy-Attenuation
Two hydistinct hyprocesses hyoccur hyduring hybeam hyattenuation: hy- hyCORRECT hyANSWER hy-• hyABSORPTION
• SCATTERING
As hythe hyprimary hyx-
ray hybeam hyinteracts hywith hyan hyanatomic hypart, hyphotons hyare hyabsorbed, hyscattered, hyand hytransmitted.
, T hyor hyf hy- hyCORRECT hyANSWERF-True
The hydifferences hyin hythe hyabsorption hycharacteristics hyof hythe hyanatomic hypart hycreate hyan hyimage hythat
hystructurally hyre hypresents hythe hypart
T hyor hyf hy- hyCORRECT hyANSWER hy-True
X-ray hyphotons hyare hycompletely hyabsorbed hywhen hythe hyenergy hyof hythe
hyprimary hyx- hyray hybeam hyis hydeposited hywithin hythe hyatoms hycomprising hythe
hytissue
T hyor hyf hy- hyCORRECT hyANSWERF-True
Complete hy of hythe hyincoming hyx-
ray hyphoton hyoccurs hywhen hyit hyhas hyenough hyenergy hyto hyremove hy(eject) hyan hyinner hyshell hyelectron.
