The dielectric wall accelerator (DWA) offers a low-cost solution for proton therapy with non-resonant waveguides. Radial waveguides (RWGs) transport electronically-switched nanosecond pulses and produce an accelerating electric field in the beam pipe. Previou...

The accessibility of proton therapy is limited by the size and cost associated with traditional acceleration techniques. The dielectric wall accelerator (DWA) was proposed as a low-cost, compact proton accelerator capable of generating suitable beams for prot...
Proton therapy (PT) has demonstrated superior healthy tissue sparing compared to photon radiotherapy for various sites; however, PT systems are expensive, which limits global availability. The dielectric wall accelerator (DWA) is proposed as a low-cost, compa...
To assess dose calculation accuracy on cone-beam computed tomography (CBCT) images relative to the RayStation CBCT correction framework (CBCTcorr) across multiple CBCT platforms, anatomical sites, and clinical scenarios.
To evaluate the feasibility and accuracy of a hyperspectral plastic scintillation detector (PSD) system (Medscint HYPERSCINT QA-200 with PRB-0019 probe)—commonly used for brachytherapy dosimetry—for Gamma Knife (GK) small-field dosimetry, and to quantify dete...
To develop and validate a female pelvis-specific deep learning deformable image registration (DIR) framework optimized for longitudinal CT imaging, enabling accurate dose accumulation and cumulative dose assessment in gynecological radiotherapy.
To investigate the optimal wall thickness for a Rexolite beam pipe for a proof-of-concept dielectric wall accelerator (DWA). In a DWA, protons are accelerated by a virtual traveling wave, created by switching electric fields along a dielectric beam pipe. The...
In Total Skin Electron Therapy (TSET) using the Stanford technique, the delivered dose is strongly affected by daily positioning uncertainties. This study presents an integrated framework that combines AI-assisted rapid generation of patient-specific six-post...
