5. Poor film processing affects:
 image quality

6. Poor film processing affects:
amount of radiation
a patient receives.

7.  The introduction of automatic film
processors eliminated problems
historically associated with manual
processing such as development of
film by sight, where the development
time was dependent on the human
observer and was very subjective.

8. Automatic processors improved
the:
 consistency of film development by
providing constant film development
time.

9. Automatic processors improved
the:
maintaininga
constant developer
temperature.

10. Good preventive
maintenance is
essential to assure a
long and trouble free
life for your processor.

11. Keeping on-going
records of
maintenance will
help assure that the
work is performed
when scheduled.

12. American Association of Physicists
in Medicine (AAPM)
 Doesnot feel there is a
need to address, once
again, the general
area of quality control.

13. American Association of Physicists
in Medicine (AAPM)
 The members of TG22 agreed
that:
 there continues to be a critical
need for more specific
guidance on how to validate
the proper operation of
automatic film processors.

14. American Association of Physicists
in Medicine (AAPM)
 The members of TG22
represent academia,
industry, government,
and practicing medical
physicists who deal
routinely with both
large and small
facilities.

15. Processoroptimization is also
complex due to the availability of:
 multiple combinations
of film types,

16. Processoroptimization is also
complex due to the availability of:
automatic film
processors,

17. Processoroptimization is also
complex due to the availability of:
chemical solutions

18. Processoroptimization is also
complex due to the availability of:
 recommended
developer temperatures.

19. Chemical Solutions
 Thechemical solutions
used in the automatic film
processor should be those
specifically recommended
by the film manufacturer.

20. Chemical Solutions
 Thestarter, developer, and fixer
solutions should be stored properly,
i.e.,
 according to the manufacturer’s
recommendations,
 and used before their expiration
date.

21. Chemical Solutions
 Inorder to assure that
these solutions have been
mixed properly, it is
preferable to mix these
solutions on-site rather than
using pre-mixed solutions.

22. Chemical Solutions
 Pre-mixedsolutions can be used, but
there must be some assurance that
these have been mixed properly.

23. Relevant metrics, such as film development
time (film immersion time) and developer
temperature, must be:
 routinelymeasured and recorded
 periodically validated for accuracy
— since the performance of the film in these chemical
solutions will depend on the development time and
temperature.

25. FREQUENCY OF TEST:
Daily

26. INSTRUMENTS USED:
Sensitometric Strip
 are made by processing under controlled
conditions of time, temperature, agitation, and
chemical activity

27. INSTRUMENTS USED:
Sensitometric Strip
 Black-and-white control
strips are normally
made in the lab, while
color control strips are
obtained from the
manufacturer of the
material being
processed

28. Sensitometry is the
scientific study of light-
sensitive materials,
especially photographi
c film.

29. The study has its origins in
the work by Ferdinand
Hurter and Vero Charles
Driffield (circa 1876) with
early black-and-white
emulsions.

30. They determined how
the density of silver
produced varied with
the amount of light
received, and the
method and time
of development.

31. INSTRUMENTS USED:
Graph Paper/graphing
paper/millimeter paper
 writing paper that is
printed with fine lines
making up a regular
grid.

32. INSTRUMENTS USED:
Graph Paper/graphing
paper/millimeter paper
 lines are often used as
guides for plotting
mathematical
functions or experimental
data and
drawing diagrams.
