Dosimetric Comparison of Proton Therapy Plans Calculated Using Fast Kv Switch Dual Energy CT Versus Single Energy CT
Dual energy CT (DECT) has been demonstrated to more accurately predict relative stopping power (RSP) for proton therapy planning over the conventional method of HU-RSP conversion using single energy CT (SECT). In this study, treatment plans are calculated in...

State of Lung SBRT across Treatment Planning Systems: Implications for Small‑Field Dosimetry
Lung stereotactic body radiotherapy (SBRT) is now standard of care for oligometastatic and small pulmonary lesions, where very small radiation fields are used. Although inhomogeneity correction algorithms have been well validated for larger fields, limited da...

High-Speed Proton Therapy In a Short Breath-Hold: A Clinically Feasible Framework for Fast, Motion-Robust Delivery for Lung Cancer Treatment
Proton therapy offers superior dose conformity compared with photon therapy but remains limited by long delivery times and sensitivity to respiratory motion, particularly for thoracic tumors. Delivering an entire proton field within a short breath-hold (5–10s...

Digital Twin–Enabled Virtual Imaging Framework for Scalable Development of Upright Radiotherapy
Upright patient positioners coupled with diagnostic-quality vertical CTs at treatment isocenter introduce significant opportunities for online adaptive particle therapy. However, limited upright data constrains our ability to rigorously test and optimize this...
