Beam Position Projection Algorithms in Proton Pencil Beam Scanning [PDF]

Cancers
Beam position uncertainties along the beam trajectory arise from the accelerator, beamline, and scanning magnets (SMs). They can be monitored in real time, e.g., through strip ionization chambers (ICs), and treatments can be paused if needed. Delivery is more reliable and accurate if the beam position is projected from monitored nozzle parameters to ...

Absolute dosimetry for FLASH proton pencil beam scanning radiotherapy

Scientific Reports, 2023
A paradigm shift is occurring in clinical oncology exploiting the recent discovery that short pulses of ultra-high dose rate (UHDR) radiation—FLASH radiotherapy—can significantly spare healthy tissues whilst still being at least as effective in curing ...
