WEBINAR: Real-time Cardiorespiratory Motion Management during MRI-guided Radiotherapy

Stereotactic radioablation is a novel, non-invasive treatment option for cardiac arrhythmias. The heart is dose sensitive and its motion contributes significantly to dose delivery uncertainties.To increase dose conformality and minimize toxicity, we explore the parallel application of respiratory MLC-tracking and cardiac-gated radiation delivery for cardiorespiratory motion mitigation for the first time, using the Modus QA QUASAR MRI4D. Cardiac and respiratory motion management decreases dose uncertainties significantly and might therefore be highly beneficial for treating cardiac arrhythmia patients in the future.
