To explain my point an example is the best.
Let's take the following materials with the following ranges
air: density 1e-3 g/cm3; HU range -1000, -800
lung: 8e-1 g/cm3; -800, -300
muscle: 1.04 g/cm3; -300, -40
soft_tissue: 1.04 g/cm3; -40, 200
bone: 1.92 g/cm3; 200, 3091
Right now the code splits these materials into
-1000 -800 Air_0
-800 -383 Lung_1
-383 -300 Lung_2
-300 -40 Muscle_3
-40 -12 Tissue_Soft_4
-12 15 Tissue_Soft_5
15 43 Tissue_Soft_6
43 71 Tissue_Soft_7
71 99 Tissue_Soft_8
99 127 Tissue_Soft_9
127 155 Tissue_Soft_10
155 183 Tissue_Soft_11
183 200 Tissue_Soft_12
200 472 Bone_13
472 745 Bone_14
745 1018 Bone_15
1018 1290 Bone_16
1290 1563 Bone_17
1563 1836 Bone_18
1836 2109 Bone_19
2109 2381 Bone_20
2381 2654 Bone_21
2654 2927 Bone_22
2927 3091 Bone_23
3091 3092 Bone_24
This is ok, but let's take a look to densities
Air_0: d=1.205 mg/cm3; n=4;
Lung_1: d=970 mg/cm3; n=13;
Lung_2: d=1.03 g/cm3 ; n=13;
Muscle_3: d=1.05 g/cm3 ; n=9;
Tissue_Soft_4: d=1.11 g/cm3 ; n=9;
Tissue_Soft_5: d=1.21 g/cm3 ; n=9;
Tissue_Soft_6: d=1.31 g/cm3 ; n=9;
.....
Tissue_Soft_11: d=1.81 g/cm3 ; n=9;
Tissue_Soft_12: d=1.89 g/cm3 ; n=9;
Bone_13: d=1.97 g/cm3 ; n=8;
Bone_14: d=2.07 g/cm3 ; n=8;
...
Bone_23: d=2.95 g/cm3 ; n=8;
Bone_24: d=2.98 g/cm3 ; n=8;
Please compare these values to the reference densities for these materials stated before and you will see my point
example Soft_Tissue: reference density 1.06 (accordingly to a reference I have) and Gate splits this material in the range 1.11 to 1.89 g/cm3, so this behaviour overestimate the density.
