RTE 1401 ACTUAL EXAM SOLVED
QUESTIONS COMPLETE PREPARATION
RESOURCE
●● direct exposure film
Answer: used without an intensifying screen, has higher resolution but
needs more XR which increase patient dose
●● fast screen-speed has...
Answer: large silver-halides and used with faster speed screen film.
is more dense, has less detail and less patient dose
●● slow screen- speed has...
Answer: small silver-halides and used with lower speed screen film.
is less dense, has more detail, and more patient dose
●● spectral sensitivity (regarding film)
Answer: the color of light to which a particular film is most sensitive
●● panchromatic
Answer: sensitive to ALL spectrums of light
,●● orthrochromatic
Answer: relatively insensitive to red spectrum
●● spectral matching
Answer: matching the color sensitivity of the film to the color emission
of the intensifying screen
●● Parts of the film processor
Answer: developer, fixer, wash tank, dryer, rollers
●● developer (film processor)
Answer: reduces (converts silver to black metallic) the film
-uses two alkaline pH agents: phenidone and hydroquinone
●● phenidone
Answer: alkaline pH agent in the developer that works FAST,
responsible for detail and producing the lighter shades in an XR
●● hydroquinone
Answer: alkaline pH agent in the developer that works SLOW and is
responsible for heavy and dark densities in an XR
●● fixer (film processor)
, Answer: holds the acidic pH clearing agents that clear the unexposed
silver from film and hardens emulsion: ammonium thiosulfate
●● wash tank (film processor)
Answer: holds water that rinses the excess chemicals
●● dryer (film processor)
Answer: uses heat to dry the film (similar to blow dryer)
●● rollers used in developer (4)
Answer: entrance rollers, crossover rollers, turn-around rollers, and
guide shoes
●● entrance rollers
Answer: determines rate of feed and indicates replenishment system
●● crossover rollers
Answer: helps film to crossover from one tank to another and acts as
squeegees to clean off excess chemicals
●● turn-around rollers
Answer: guides film to turn aroundto exit each vat
