Paper Abstract

A new silver halide material, 3M Company's Type HL film, for clinical x-ray imaging either with or without an intensifying screen, can be handled under relatively high room-illumination levels and therefore requires no dark-room. Evaluation of this new film in comparison to 3M Company's conventional Type R film shows Type HL to be equivalent or superior: The relative speeds are approximately the same, and the resolution and MTF of Type HL are slightly better than of Type R. Type HL is sensitive to the same wavelengths as the spectral emission of the intensifying screens but is insensitive to the wave-length emission region of present x-ray darkroom safe-lights or the new high-light-level filters supplied by 3M. Although the evaluation discussed here is based on clinical uses, the film promises to be advantageous in industrial radiology.
