PROCESSORS/DARKROOMS QUALITY CONTROL TESTS
Section I. AUTOMATIC PROCESSOR ACCURACY TEST
Where does the radiographic process really begin and end? In the darkroom!
The way the radiographic film is handled from the beginning (opening of the film
cartons) to the final step (dropping the film into the processor film bin) determines the
quality of the finished radiograph. No wonder that extreme care needs to be taken
when working in the darkroom and with processors. This lesson will cover the critical
areas in the handling of radiographic film. The first test is for automatic processor
a. The automatic processor accuracy test establishes the normal operating level
of the automatic processor, and the normal level means the optimum level. When you
know this level you have a standard for daily quality control.
b. The automatic processor accuracy test should be performed:
At or prior to the start of a quality assurance program.
After major repairs.
(3) After major cleaning, which is when, all the tanks and lines are emptied
and flushed. This is not a daily or weekly cleaning.
(4) In accordance with your clinic standing operating procedure (S0P) which
may be quarterly, biannually, or annually.
a. A sensitometer, which puts densities on the film (see figure 7-1).
b. A densitometer, which reads the densities (see figure 7-2).
