Table 5.4 ROI Measurements table<br />
Item Description<br />
Measurement<br />
Types<br />
Make a selection from the drop-down list to specify the type of ROI<br />
measurements to include in the table.<br />
None Exclude ROI measurements from the table.<br />
Counts Includes Total Counts, Avg Counts, Stdev Counts, Min Counts, and Max<br />
Counts in the table.<br />
Total Counts = the sum of all counts for all pixels inside the ROI.<br />
Avg Counts = Total Counts/Number of pixels or super pixels.<br />
Stdev Counts = standard deviation of the pixel counts inside the ROI<br />
Min Counts = lowest number of counts in a pixel inside the ROI.<br />
Max counts = highest number of counts in a pixel inside the ROI.<br />
(For more details on count units, see page 199.)<br />
Note: These numbers are displayed if the units selected in the ROI<br />
Measurements table and the image are the same. Otherwise, N/A appears in<br />
each column.<br />
Photons Total Flux = the radiance (photons/sec) in each pixel summed or integrated<br />
over the ROI area (cm2 ) x 4π.<br />
Average Radiance = the sum of the radiance from each pixel inside the ROI/<br />
number of pixels or super pixels (photons/sec/cm2 /sr).<br />
Stdev Radiance = standard deviation of the pixel radiance inside the ROI<br />
Min Radiance = lowest radiance for a pixel inside the ROI.<br />
Max Radiance = highest radiance for a pixel inside the ROI.<br />
(For more details on photon units, see page 199.)<br />
Efficiency Available for fluorescent images only. Includes Total Efficiency, Average<br />
Efficiency, Stdev Efficiency, Min Efficiency, and Max Efficiency in the table.<br />
(For more details on efficiency, see page 199.)<br />
Click<br />
Attributes<br />
Make a selection from the drop-down list to specify the click number (image<br />
file) information to include in the table. Click attributes include label name<br />
settings and camera settings.<br />
None Excludes click attributes from the table.<br />

in the table.<br />
Includes only the click attributes with values in the table.<br />
Includes all Xenogen Default label name settings in the table.<br />
Make a selection from the drop-down list to specify the ROI dimensions to<br />
include in the table.<br />
None Excludes the ROI area, x,y-coordinates, and dimensions from the table.<br />
Pixels Includes ROI area, x,y-coordinates, and dimensions (in pixels) in the table.<br />
cm<br />
Copy<br />
Includes ROI area, x,y-coordinates, and dimensions (in cm) in the table.<br />
Selected Copies the selected row(s) in the table to the system clipboard.
