Midterm Flashcards
radiography of the breast, fine grain, single emulsion, greater detail
MAMMOGRAPHIC FILM
xray gamma rays
THERAPY LOCALIZATION FILM
intraoral film: periapical film, bitewing or inter proximal film, occlusal film. Extraoral: panoramic
DENTAL X-RAY FILM
single emulsion exposed in device called multiformat camera or laser camera. Materials used: aluminum oxide, tin filter, copper filter
VIDEO FILM
measures RAD
DOSIMETERS FILM
for higher energy adiography
INDUSTRIAL FILM
serial radiography
AUTOMATIC SERIAL CHANGER FILM
paper bases
POLARIOD RADIOGRAPHIC FILM
laser print
LASER FILM
single emulsion film with sprocket holes
MRI CT-SCAN CINE FILM
name of px on top, must be done b4 processing film
FILM ID PRINTER
Is the regulatory process through which the actual quality performance is measured, compared with existing standards and action necessary.
FILM/IMAGE ANALYSIS
Is all those planned and systematic actions necessary to provide adequate confidence that a product or service will satisfy the given requirements for quality radiograph. WHO recommended a permissible reject rate of 5%
REJECT FILM ANALYSIS
minimize px exposure, cost reduction, high throughtput, better image quality.
OBJECTIVE OF REJECT FILM ANALYSIS-
artifacts, mispositioning, over collimation, px motion, double exposure, inadequate inspiration, overexposed (too dark), underexposed (too light), marker missing/wrong, wrong exam, wrong px, film lost in processor
CONVENTIONAL REASON FOR REPEATED EXAM
Digital radiography most frequent factor responsible for re take x-ray is
positioning error (30%), underexposure (28%), overexposure (26%), px movement (6%), portable procedure (1%), grid cut off (0.5%), others (8.5%)
Poor screen-film contact, improper use/positioning of a grid, double exposure, px motion, poor px prep
Exposure artifacts
Will leave deposits on film, areas of increased or reduced density, occationally some sludge may not br washed off and dried onto film
Dirty roller
Improper or inadequate chemistry, leaves a uniform dull gray haze on film, may also be seen in two diff colors
Chemical fog
White light leaks, safelight too close or wrong wattage, film left in x-ray room during exposure
Light or radiation fog
Are sprung or improperly positioned, ridges in __ press against film leaving an artifact
Guide shoe
Dirt or stain on a roller, 3.14 inches apart
Pi-lines
Irregular or dirty rollers
Pressure marks
Improper handling or storage, appears as a fingernail mark
Kink marks
