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

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 whithin 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): self-explanatory
  • Use linear interpolation: self-explanatory
  • 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
