4. Evaluation Results
When you click the Start Evaluation button, the system
calculates the planned volume within the evaluation
limits.
The evaluation results are displayed in segment 4. Only
the statistic parameters that are set in the configura-
tion dialog box are calculated. Volume pixels and eval-
uation results are the same color.
The evaluation results and the thick slice images are
both displayed in segment 4. To switch the display,
click the MIP/Result icon.
The evaluation results include general patient informa-
tion, date and time of the evaluation and for each vol-
ume the configured statistic parameters.
• Volume [cm3/mm3] Size of the volume.
• Height [cm/mm] Maximum height of the volume in
cm – corresponding to the patient’s anatomical feet-
to-head orientation.
• Width [cm/mm] Maximum width of the volume in
cm – corresponding to the patient’s anatomical left-
to-right orientation.
• Depth [cm/mm] Maximum depth of the volume in
cm – corresponding to the patient’s anatomical ante-
rior to posterior orientation.
• Mean [HU] Mean CT value of the volume in HU.
• SD Standard deviation from the Mean value [HU].
• L Threshold [HU] Lower threshold considered for
automatic volume detection.
• U Threshold [HU] Upper threshold considered for
automatic volume detection.
• L Eval Limit [HU] Lower evaluation limit considered
for volume calculation.
• U Eval Limit [HU] Upper evaluation limit considered
for volume calculation.
