Proton transmission fields, treating through the target rather than stopping spots in the target, have a substantial but largely unrealized clinical potential, offering inherently robust delivery with minimal range uncertainty and faster treatment times. To i...

Proton therapy shielding design typically assumes that protons stop within the patient. However, modern treatment planning optimization strategies may introduce high-energy proton transmission (“shoot-through”) spots that exit the patient and deposit energy i...

Respiratory motion and delivery dynamics can affect delivered dose in scanned proton therapy, particularly for thoracic treatments. Many existing motion-evaluation approaches rely on simplified delivery assumptions or research-only implementations, limiting t...
