A Sensitometric Evaluation of Film-Chemistry-Processor Systems in the State of New Jersey

摘要

A sensitometric evaluation of film-chemistry-processor systems in medical x-ray facilities was carried out in the State of New Jersey. Processor operating parameters such as developer temperature were measured and sensitometric indices (Base + Fog, sensitometric speed step corresponding to speed density, and average gradient) were determined for both control film and film routinely used in each facility processed in each chemistry-processor system. Sensitometric speed varied in excess of a four-fold range of sensitometric exposure. This would correspond to a four-fold range of patient exposure for a given image receptor.
