You can use the Horizon Bracketing™ function to assist you in
determining the gamma, contrast, saturation, and MCM (Medical
Color Matching) settings that will result in the desired appearance
for printed images.
This chapter explains how to print gamma/contrast/saturation
(GCS; for PostScript, referred to as “GCT”) or MCM bracketing
sheets via DICOM or PostScript, then how to use the print to select
the desired settings. For information about how to print bracketing
sheets using FTP or LPR, refer to the
Horizon Imager Technical
Manual
.
NOTE:
Image parameters—including Dmax, gamma, contrast, saturation, and MCM—are
intended to compensate for differences that may occur between image acquisition and
image printing. These parameters allow you to adjust the appearance of a printed image so
that it is satisfactory for your application. Care should be used when setting these
parameters to avoid overcompensation. Refer to Appendix D for typical setting ranges.
DirectVista
is optimized for grayscale prints, while
ChromaVista
is
optimized for color prints. If
ChromaVista
is not giving you
satisfactory results with grayscale images, you may want to consider
using
DirectVista
media for those applications.
