Automatic film processing typically processes a film in?
1.) Transport system 2.) Dryer system 3.) Replenishment system 4.) Circulation system 5.) Temperature control system
The automatic processing components are considered complex and utilize several subsystems to completely process a radiograph that include?
1.) Developing 2.) Fixing 3.) Washing 4.) Drying
Primary Automatic Processing steps are composed of?
Stage of processing which the latent image is converted a visible image. It is very short and highly critical to the film processing sequence.
The developing temperature is usually maintained at ___ º F?
Developing typicall occurs in ___ seconds.
Removes remaining silver halide from emulsion and hardens gelatin.
Removes any excess chemicals from the previous processing steps.
Wash water should be maintained at __º F lower than developer temperature.
Washing typically occurs in ___ seconds.
Removes water and prepares the film for viewing.
The air temperatures range for drying is ____ - 150 º F.
Drying typically occurs in ___ seconds?
What is designed to move film through components of the processor?
1.) Rollers 2.) Transport rack subassembly 3.) Drive Motor Subsystem
Transport system consists of what principle subsystems?
1.) Transport 2.) Master 3.) Planetary
Roller subassembly consist of what types of rollers?
They convey the film along its path.
It is - used when the film makes a turn in the processor.
It is - positioned around the master roller with metal or plastic guide shoes.
Transport Rack Subassembly
They are easily removable and provide for convenient maintenance and efficient cleaning of the processor and uses guide shoes to guide film around bends.
Systems that consist of a master roller, planetary rollers, and guide shoes is called a? It is located at the bottom of the transport rack assembly.
As film exits the top of the rack assembly, it is guided to the adjacent rack assembly through a?
Drive Motor Subsystem
A chain, pulley, or gear assembly transfers power to the transport rack and drives the rollers.
Thermocouple or Thermistor
Temperature is monitored at each stage by a ______ and is controlled thermostatically by a controlled heating element in each tank.
Replaces chemicals that are depleted in developer and fixer. It is accomplished by metering the proper quantities of chemicals into each tank to maintain volume and chemical activity.
Designed to continuously pump the developer and fixer in order to maintain constant agitation within each tank and uses water that is circulated through the wash tank to remove all of the processing chemicals from the surface of the film before drying.
Consists of a blower, ventilation ducts, drying tubes, and an exhaust system. Functions to extract all residual moisture from the processed radiograph, so it can drop into the receiving bin dry.
Negative Internal Air Pressure
Dryer systems should be run at a _____ so that air is continually being sucked in and the fume-laden moist air vented externally.
Quality Control (QC) in Diagnostic Radiology
It requires a planned continuous program of evaluation and surveillance.
1.) Periodic cleaning 2.) System maintenance 3.) Daily monitoring
Quality Control (QC) in Diagnostic Radiology consists of?
Refers to routine procedures, usually performed weekly or monthly. Maintenance of all moving parts for wear.
Planned program of part replacement at regular intervals before equipment failure.
Failure in the system that requires processor repair is a nonscheduled event.
It is any irregularity that is not caused by the proper shadowing of tissue by the primary x-ray beam.
