RAD 165 CONTRAST WITH COMPLETE SOLUTIONS
100% VERIFIED!!
________ is the difference between adjacent densities - ANSWER Contrast
What are the Two factors that allow detail - ANSWER Density & Contrast
________is considered the controlling factor of contrast - ANSWER kVp
range of brightness as displayed on a monitor - ANSWER Dynamic range
What is window width? - ANSWER the digital processing produces change in range of
brightness which is used to control contrast
High Contrast - ANSWER HIGH CONTRAST
Few shades of gray
Increased contrast
Low kVp
Short scale contrast
Short (narrow) dynamic range/window width
Low Contrast - ANSWER LOW CONTRAST
Many shades of gray
Decreases contrast
High kVp
Long scale contrast
, Large (wide) dynamic range/window width
