PROCESSOR QUALITY-CONTROL IN LASER IMAGING-SYSTEMS

Sensitometric techniques for performing processor quality control in l aser imaging systems are analyzed in this study. The sensitivity of co nventional x-ray films using simulated screen-light sensitometry is co mpared with helium-neon (HeNe) laser film exposed with a simulated red -light sensitometer, a standalone (reference) laser sensitometer, an e xperimental (unstable) laser sensitometer, and laser printers. Infrare d (IR) laser film exposed with an IR laser diode and a simulated IR se nsitometer are also evaluated. It is demonstrated that laser-generated step tablets provide an easy and reliable method of performing laser film processor quality control. (C) 1997 American Association of Physi cists in Medicine.
