5-5. Modality Groups
The current file of Modality (Contrast Table) Groups, "Luts86-G5B.txt" (Luts86-G5B-1.txt and
LutsS86-G5B-2.txt), displays 6.G.5B on the local panel for the "Contrast Tables" in the Software
Versions menu. The following are the Contrast Tables located in the Modality Groups 0-10 for the file
Luts86-G5B:
0 – UPMSV3K – "Saggy" curves – Same as Group 1 for the 8300. *
1 – U693C0 – "S-shaped" curves – Same as Group 2 for the 8300. *
2 – U713C0 – "S-shaped" curves with elevated brightness – Same as Group 3 for the 8300. *
3 – GSDF6 – Grayscale Standard Display Function, with varying D-max – See description below.
4 – GSDF6LL0 – Grayscale Standard Display Function, with varying lightbox luminance –
See below.
5 – GSDF6AA0– Grayscale Standard Display Function, with varying ambient light – See below.
6 – LORAD03 – Special set of curves specifically designed for Lorad.
7 through 10 – UPMSV3K
* See 8300 Tech Bulletin 11-4/98
GSDF6 – All its contrast tables are based on the NEMA Grayscale Standard Display Function,
parameterized with a D-min of 0.2, a lightbox luminance of 2000 cd/sq.m., and an ambient light
fraction of 0.005.("Light fraction" is the amount of reflected ambient light coming off the film,
expressed as a fraction of the lightbox luminance) For this ULUT Set, the parameter which varies as
the contrast setting is changed is D-max. As the contrast setting is changed from 1 through 12, the
D-max parameter goes through the following sequence of values: 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7,
2.9, 3.1, 3.3, 3.5.
GSDF6LL0 – All its contrast tables are based on the NEMA Grayscale Standard Display Function,
parameterized with a D-max of 3.5, a D-min of 0.2. For this ULUT Set, the parameter which varies as
the contrast setting is changed is the measured luminance of the lightbox in cd/sq.m. As the contrast
setting is changed from 1 through 12, the luminance is varied through the following sequence of
values: 2000, 2210, 2442, 2699, 2982, 3295, 3641, 4024, 4447, 4914, 5430, 6000 cd/sq.m.,
respectively.
GSDF6AA0 – All its contrast tables are based on the NEMA Grayscale Standard Display Function,
parameterized with a D-max of 3.5, a D-min of 0.2, and a lightbox luminance of 5500 cd/sq.m. For
this ULUT Set, the parameter which varies as the contrast setting is changed is the ambient light
fraction, i.e., the amount of reflected ambient light coming off the film, expressed as a fraction of the
lightbox luminance. As the contrast setting is changed from 1 through 12, the ambient light fraction
parameter goes through the following sequence of values: .001, .002, .003, .004, .005, .006, .007,
.008, .009, .010, .011, .012.
