Geometric Details

spot size, sid, oid, degree of motion

factors governing geometric detail:

smallest

(longest or smallest) focal spot should be used

longest

(longest or smallest) standard SID

close/in contact

OID should be _ / _with film

time

motion affects recorded detail bcuz it fails to permit enough __ for a well-define image to form

recorded detail

the sharpness of the lines of the image

poor

(sharp or poor) recorded detail is seen as a fuzzy or blurry edge around the lines

light difussion

poor screen-film contact reduces recorded detail because of the degree of _ _ in the areas of poor contact

magnification, blurring

decrease in SID = increase __ and __

recorded detail

motion affects __ because it fails to permit enough time for a well-define image to form

recorded detail

is the sharpness of the lines of the image

voluntary, involuntary

two types of motion

voluntary

actions that can be controlled by the body

involuntary

motions that cannot be controlled by the body

motion sharpness

loose of radiographic quality caused by the movement of the patient

visibility of detail

ability to visualized recorded detail when image contrast and optical density are optimized.

collimation, use of grid, other methods used to reduce scattered radation 

factors governing visibility of detail
