Module Description
The DoseComparison module computes the difference between two co-registered dose volumes using the gamma dose distribution comparison method. This module uses the gamma Plastimatch algorithm internally.
Use Cases
Comparing dose distributions
Tutorials
Panels and their use
- Reference dose volume: Dose distribution used as reference
- Evaluated dose volume: Dose distribution used as evaluation/compare
- Mask structure: Segmentation and contained segment within which the gamma index is calculated, but not outside (it will be 0)
- Distance-to-agreement (DTA): Mark dose voxel as failed if closest dose voxel with same value found in distance higher than this threshold, see Low paper below
- Dose difference criteria: Mark dose voxel as failed if dose difference is equal or greater than this threshold, see Low paper below
- Maximum value / Custom: Reference dose value for threshold can be either the maximum dose in the dose map, or a custom cGy value
- Do not calculate gamma values for voxels below analysis threshold
- Use linear interpolation
- Upper bound for gamma values: If gamma value would be higher than this value, the value will be set instead
- Dose threshold on reference only
- Gamma volume: Output volume to contain gamma map. Needs to be created using the combobox. Name will be automatically filled from the names of the input volumes
