Dose Location Histogram (DLH)DLH gives an idea about the location of cold / hot spots within a structure relative to its surface.

Eg: 85cc of cold spots (Dose <= 70Gy) lie within 1.4 cm from the surface

Generating Consensus ContourGraph of Agreement volume v/s Confidence level for the three methods: Apparent, kappa-corrected and STAPLE. User can interactively select the confidence level by dragging the red line and consensus regions will be updated accordingly. This process would change the estimated volume to match desired confidence level.

Fast 3D Gamma Metric Based on "A fast algorithm for gamma evaluation in 3D”, Wendling et al, Medical physics, 34 (5), p. 1647, 2007. Works with doses of unequal dimensions and having associated transformations. Computation time for regular doses is ~2 seconds.
