ART: margins for the boosting phase

- Margins as the local distance between ref contour and high-probability contour (for instance 90% ≈ missing 1/9 fractions)

- Splitting the rectum in 8 sectors (anysotropic motion)

- Assessing for each sector the «best» margin value based on the % of voxels (95-99%) included in the high-probability contour

- Prospectively evaluating the appropriatness on an independent population
