Real-time dose verification remains a critical unmet need in radiation therapy. We developed physics-informed AI models for radiacoustic imaging (RAI) to enable quantitative, real-time in vivo dose monitoring for proton therapy. Our approach addresses two big...

Dynamic Individual Spot Collimation In Proton Beam Scanning with a Robotic Arm–Driven Pinhole Aperture
Static apertures in pencil beam scanning (PBS) proton therapy improve lateral dose falloff but are optimal only for a single energy layer and perform poorly for shallow targets where range shifters increase spot size. This work proposes dynamic individual spo...

3D Protoacoustic Image Reconstruction Using a SAM-Med3D Foundation Model
Protoacoustic (PA) imaging enables real-time verification of proton dose deposition by reconstructing 3D initial pressure maps from acoustic signals generated during proton delivery. However, in practical treatment settings, detectors cannot fully surround th...
