Ion-beam CT improves particle therapy planning
By Tami Freeman, PhD
A better option for particle therapy treatment planning would be to use protons or other ion beams. Instead of incorporating an error margin of around 3% as with x-ray CT images, ion CT provides a direct estimation of relative stopping power and eliminates conversion uncertainties.
