Set 0: U1_109B (C = 1 through 6)
The first 6 ULUTs, contrast settings 1 through 6, of the U1_109B ULUT Set are "saggy" (i.e., non
S-shaped) curves, as indicated in Figure 2-4. These are the most-used subset of the UPMSV3K ULUT
curves, which will reside in the Modality Groups as Set 1.
For these curves, overall image brightness increases as the Contrast setting is increased from 1 to 6.
These curves are often preferred over S-shaped curves by radiologists who are working with
MODALITIES such as ultrasound or nuclear medicine.
Set 0: U1_109B (C = 7 through 12)
The remaining ULUTs, Contrast settings 7 through 12, of the U1_109B ULUT Set consists of 2 groups,
each comprised of 3 S-shaped curves (see Figure 2-5).
The group using curves 7, 9, and 11 is brighter than the other group using curves 8, 10, and 12. Within
either group, increasing the Contrast setting increases the mid-tone contrast and decreases the contrast
in the near-black and near-white portions of the input range. The reason for indexing by 2 instead of 1 in
this ULUT Set is to make a 2x3 image contrast test film easier to study visually, since all 3 images for a
brightness group will be in the same column on the film. Curves 7, 9, and 11 are a subset of the 713C0
ULUT Set, Modality Group Set 3. Curves 8, 10, and 12 are a subset of the 693C0 ULUT Set, Modality
Group Set 2. The applicability of the 693C0-type and 713C0-type curves to various MODALITIES is
described in the descriptions of the 693C0 and 713C0 ULUT Sets.
