IMAGE QUALITY

Processing

Even a picture which has been properly exposed and skillfully
executed can easily lose in quality in a poor development process.
The film processing machine is the heart of the mammography
department. Deterioration in image quality can often be traced to
a disorder in the development process.
Modern film processing machines can be programmed for various
processing times, which means that the processing time can be
adapted to mammography film.
The development temperature should be approximately 35°C (95°F).
Chemicals suitable for mammography film should be chosen
and be mixed in small tanks, so that they always are "fresh".
Replenishment should be adapted to mammography film.
The film processing machine should be inspected daily. The
temperature, film speed, film contrast and film base fog should be
controlled. For this purpose, a sensitometer and a densitometer
are required.
