AI-Driven Radiacoustic Imaging for Proton Therapy Monitoring

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...

First-In-Human Study of 3D Protoacoustic Imaging for Proton Therapy Monitoring

Proton therapy is an increasingly adopted cancer treatment due to its high dose conformity enabled by the Bragg peak (BP), reducing radiation exposure to surrounding healthy tissue. However, this steep dose gradient makes treatment accuracy highly sensitive t...

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...

Image Guidance in Upright Radiotherapy

Upright patient positioning is transitioning rapidly from concept to clinic in both photon and proton therapy, supported by compact treatment systems, innovative immobilization devices, and the development of upright imaging platforms. Early studies highlight...
