A dynamic anthropomorphic phantom for end-to-end testing in image- and surface-guided adaptive radiotherapy.

ABSTRACT:

Background

Respiratory and digestive motion can compromise the accuracy of radiotherapy (RT), affecting tumor targeting and healthy tissue sparing. Current phantoms often fail to replicate complex organ movements and lack compatibility with advanced imaging modalities like magnetic resonance imaging (MRI) and 4D computed tomography (4DCT), limiting their utility in adaptive radiotherapy. The BRaVIDA (Breathing Radiotherapy Visual monitoring, Imaging, and Dosimetric Anthropomorphic) phantom addresses these limitations by simulating realistic organ motion during breathing and digestion. Its MRI compatibility allows for comprehensive testing in adaptive radiotherapy workflows, improving motion management and treatment precision for both photon and ion beam therapies.
