TOPIC-DUPLICATING RADIOGRAPHY

2. DUPLICATING RADIOGAPHY
• Duplicating radiography is a process,in which process we can
duplicate exposed processed film.

3. PURPOSE
• Our duplicating film is a
single emulsion film. It is
designed to produce
accurate copies of
conventional radiographs
and video images using
white or ultraviolet light
source.

4. REASONS FOR DUPLICATION-
Duplicate copies of radiographs may be required for a number of
reasons:
(1) For transfer with the patient to another hospital. This allows the
original radiograph to be retained in safety at the hospital.
(2) For display in exhibitions, or as part of a film archive or X-ray
museum, perhaps as an example of a rare pathology.
(3) For publication in a book or learned journal.
(4) For teaching purposes in a radiography or medical school.

5. DUPLICATING FILM
Is a single emulsion film.
The color of emulsion layer side is
salmon pink.
The non-emulsion layer backing is a
forest green color.
 Individual sheets of duplicating film are
triple-notched in the upper right hand
corner.

6. DUPLICATING EQUIPMENT
1. Simple contact printer
2. A safelight
3. A white light source
4. An ultraviolet source

7. METHOD
• Lay Manual Duplicator on counter top and open it.
• Turn off overhead white light. Safelight is OK to leave on.
• Lay the duplicating film (purchased separately) on top of black plastic
portion of the duplicator.
• Duplicating film has an emulsion side (purple in color) and a none
emulsion side (Black shinny side). The emulsion side is face up with the
notch in the upper right hand corner.
• Place your film on top of the duplicating film. Align both films.
• Close the clear plastic top.
• Expose the duplicator with white light (75 watt bulb) at a distance of four
feet for 4 seconds. A black light may also be used.

8. PROCESSING
• As with all film, it is essential that
proper processing be maintained
with regular replenishment.
• After exposure we have to
processing the film.
