Abstract

An intelligent developer replenish system was developed for automatic film processor. The system detects the gray level of a developed film and determines the amount of the developer to be added to the system. Using the film darkness detection system, it was found that the film darkness is inversely proportional to the amount of light exposure, that the developer retrograde after developing certain number of films without replenishment and the number is dependent upon the parts of the body, and that the developer does not retrograde when 30 ml of developer is added after each chest film processing. The use of this system resulted in a decrease in the amount of developer by 40%.
