- Automation.
A machine that
automates film
processing through
different stages,
including developing,
fixing, washing, and
drying.
- Benefits
Ensures consistent
film quality, reduces
processing time, and
minimizes chemical
exposure to radiologic
technologists.
3 Components
Includes mechanical and chemical systems that
assist in film processing.
Automatic Processor
Used for manual film processing,
positioned opposite the loading bench to
prevent solution splashes in the Dry
Section.
Processing Tank
Parts of the
Processing Tank
Master tank
Insert tank
Acts as a jacket to hold the insert tanks.
Provides a water compartment between insert tanks
for rinsing and washing films.
Master Tank
A removable container that holds individual chemical
solutions (developer, fixer).
Made of stainless steel or hard rubber plastic for
durability and resistance to chemicals.
Insert Tank
Used for rinsing films after fixing,
ensuring all residual chemicals are
removed.
Allows more films to be processed
efficiently within a short period.
Wash Tank
Types of Wash Tanks
Single compartment wash tank
cascade wash tank
Fresh water continuously circulates over the film surface.
Connected to a water pipe with drainage hole on the opposite
side of the water inlet for excess water removal.
Single Compartment Wash Tank
Divided into two compartments:
First stage: Initial washing.
Second stage: Final washing for complete chemical removal.
More effective than a single compartment wash tank.
Water flows from bottom to top, preventing contamination.
Cascade Wash Tank
Stainless steel clips used to hold films during
processing
Processing Hanger
Functions of Processing Hanger
Provides easy handling of films.
Supports films during chemical immersion.
Prevents films from sticking together.
Allows multiple films to be processed
simultaneously.
Types of Processing Hangers
sheet film hanger
dental film hanger
whole film hanger
Has crossbars and a rigid frame
with four clips.
Used for large radiographic
films.
Sheet Film Hanger
Specially designed for dental radiographs.
Made of stainless steel with
attached film clips
Dental Film Hanger
Used for 10mm roll films
(fluorography).
Whole Film Hanger
Measures the temperature of processing
solutions to maintain optimal chemical
activity.
Helps prevent image distortion due to
incorrect temperature.
Thermometer
1 Used for preparing
and mixing chemical
solutions for film
processing.
2 Requires two separate
sets:
One for developer.
One for fixer.
Mixing Equipment
Tools used in mixing:
– Ensures easy pouring of solutions.
– Used for stirring
solutions.
Plastic funnel
Stainless steel or paddle
Protects the technologist’s uniform from
accidental chemical spills.
Made of plastic or water-resistant fabric.
Waterproof Apron
Used for holding wet films after washing
Includes a drainage hole to remove excess water
before drying.
Wet Film Brackets
Ensures proper drying before films are sent for
interpretation or storage.
Prevents scratches and damage, which are more
likely when the film is wet.
Film Dryer
– Generate controlled heat for drying.
Heating elements
– Directs air onto the film surface for uniform drying.
Blower
– Prevents excessive humidity and heat buildup in
the darkroom.
Fan circuit
Importance of Drying
Wet films are prone to scratches and damage.
Dry films are easier to handle and store.
Importance of the Wet
Section
The Wet Section is the heart of radiographic film
processing. Proper chemical handling, washing,
and drying procedures are critical for high-quality
radiographs. A well-maintained wet section
ensures efficient workflow and minimizes film
processing errors.
MAINTENANCE OF A
PROCESSING TANK
Proper maintenance of the processing tank is
essential to ensure consistent film quality, prevent
contamination, and extend the lifespan of the
equipment. Regular cleaning prevents the buildup
of chemical residues, algae, and stains that could
affect radiographic images.
