Flood replenishment: a new method of processor control

In mechanized radiographic film processors that process medium to low volumes of film, roll films, and those that process single-emulsion films from nuclear medicine scans, computed tomography, and ultrasound, it is difficult to maintain the developer solution at a stable processing level. We describe our experience using flood replenishment, which is a method in which developer replenisher containing starter solution is introduced in the processor at timed intervals, independent of the number of films being processed. By this process, a stable level of developer activity is maintained in a processor used to develop a medium to low volume of single-emulsion film.
