International audience. This study aims to improve real-time respiratory motion tracking through an algorithm having increased robustness to gray-level intensity variations from other sources than motion. These developments are shown to be potentially beneficial for magnetic resonance-guided (MRg) high intensity focused ultrasound (HIFU) and external beam radiotherapy (EBRT) interventions in the abdomen, where cardiac activity might become problematic for current approaches.
