Radiographic Technique Relationship Flashcards
is the primary controlling factor of density it determines the total quantity of xrays produced
mAs
density is ___ to mAs
directly proportional
affects the intensity of the xray beam reaching the receptor due to the divergence of the beam
SID
density is ___ to the sqaure of the SID
inversely proportional
affects the energy and penetration ability of the xrays
kVp
density is _____ related to kVp, but not linearly
directly
increasing kvp ??
decreasing kvp??
allows more xray to penetrate
reduces the penetration ability
density is ____ to the thickness of the patients body art being imaged
inversely proportional
density is _____ related to the density of the tissue being imaged
inversely
directly affects radiographic density (positive or negative)
contrast media
to enhance the visualization of anatomical structure by altering local density and contrast
Contrast Media
(tumors, pneumonia, fluid accumulation) increase tissuee density absorbing more xray
Additive pathologies
emphysema, osteoporosis decreases tissue density allowing more xray to pass through
Destructive pathologies
density is ____ to the developer temperature n film processing
TEMPERATURE
Directly proportional
density is _____ to the amount of time the film spends in the developer solution
TIME
directly proportional
density is _____to the strength and activity of the developer solution
CHEMICAL ACTIVITY
directly proportional
