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...

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...

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...

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...
