GRID-Lattice: A Compact and Robust Proton Lattice Strategy Using a GRID Entrance Beam Pattern
Proton LATTICE radiotherapy (LRT), a spatially fractionated radiotherapy (SFRT), delivers high dose to intratumoral vertices while maintaining low valley dose. Single-field optimization (SFO) is robust in preserving peak-to-valley patterns but may increase en...

Intra-Field Interruption In Pencil Beam Scanning Proton Flash Radiotherapy: Dosimetric Impact and Clinical Solutions
Ultra-high-dose-rate (UHDR) proton irradiation may spare normal tissue (FLASH effect), but PBS proton dose rate is limited by machine constraints (minimum MU/spot and dwell time). Intra-field interruptions can leave sub-threshold MU for remaining delivery, de...
