TABLE 2.
Next-image parameters were measured using our parameter estimation software for various organs.
| Tissue type | μT (cm−1) (n) | μT (cm−1)4 | σ (μm) |
|---|---|---|---|
| Heart (n = 19) | 267 ± 47.6 | 182–312 | 9.1 ± 2.1 |
| Fatty tissue (n = 23) | 254 ± 46.4 | 165–676, 202 | 12.2 ± 2.7 |
| Liver (n = 14) | 218 ± 27.1 | 50.8–304 | 7.5 ± 1.7 |
| Muscle (n = 22) | 214 ± 41.5 | 41–345 | 9.0 ± 2.1 |
| Kidney (n = 16) | 207 ± 34.7 | ( ) | 6.6 ± 1.6 |
| Adrenal gland (n = 19) | 206 ± 29.7 | ( ) | 5.8 ± 1.3 |
| Brain (n = 21) | 161 ± 27.4 | 52.6–687 | 11.2 ± 1.7 |
Attenuation coefficients and σ values as determined by our parameter estimation software are shown in the second and fourth column respectively along with the standard deviation. The number of measurements taken is displayed along with the tissue type in parenthesis. The range of reported values is shown in the next column if such values were available. For the fatty tissue a value of 202 cm−1 is shown in italics representing the closest value to the wavelength of GFP.4 In other tissues no values were reported at wavelengths closely matching the emission wavelength of GFP. All parameters except those for the adrenal gland were determined from images taken of the mouse perfused with microspheres. Parameters for the adrenal gland were determined from images taken from the mouse injected with GFP positive LLC cells.
