Description
Julian Schwengfelder and co-authors refine dose planning for proton therapy in a 2026 paper. Proton beams stop inside the body, and planners predict that stop point from dual energy CT scans. Body size shifts the scan values, so a size fix based on water like thickness is applied slice by slice.
Two new ways to gauge thickness use all voxels in each slice, while the older way used peak values in two directions. The new ways held up better when shapes turned or were far from round. On patient scans they agreed with each other but parted from the old way at large sizes, shifting proton range a small yet real amount.
