Paper Abstract

Three different types of phototimer systems are compared, utilizing a simple method for performance evaluation. A phototimer system using an ionization chamber as a radiation sensor located between the grid and the film cassette is found to be the most reliable phototimer system and is therefore recommended for phototiming techniques. The minimum reaction time of the phototimer system and the backup timer are also discussed briefly.
