The feasibility of image registration of hyperpolarized 3-helium (3He) MRI and radiotherapy treatment planning CT is demonstrated for six patients with non-small cell lung cancer (NSCLC). Knowledge of lung function derived from 3He images may enable radiation fields to be targeted to limit the treatment dose to healthy regions of lung and therefore reduce the risk of radiation pneumonitis.
