Linear Attenuation Coefficients and Windows for Generation and Segmentation of μ-Maps*
| Segmentation | |||
| Segment | Generation | Lower | Upper |
| Air | 0 | 0 | 0.040 cm−1 |
| Adipose | 0.090 cm−1 (21) | 0.040 cm−1 | 0.095 cm−1 |
| Soft | 0.100 cm−1 (9) | 0.095 cm−1 | 0.110 cm−1 |
| Bone | 0.172 cm−1 (22) | 0.110 cm−1 | ∞ |
↵* For example, adipose tissue is assigned a coefficient of 0.09 cm−1 in generation of maps; in segmentation, adipose tissue is defined by 0.04 cm−1 ≤ μ < 0.095 cm−1.
