Background: This study aimed at evaluating spatially varying instantaneous dose rates for
different intensity-modulated proton therapy (IMPT) planning strategies and delivery …

Particle therapy is rapidly expanding and claiming its position as the treatment modality of
choice in teletherapy. However, the rate of expansion continues to be restricted by the size …

Purpose In ultrahigh dose rate radiotherapy, the FLASH effect can lead to substantially
reduced healthy tissue damage without affecting tumor control. Although many studies show …

The concept of spatial fractionation in radiotherapy was developed for better sparing of
normal tissue in the entrance channel of radiation. Spatial fractionation utilizing proton …

Hadron therapy installations are evolving towards more compact systems that require higher-
quality beams for advanced treatment modalities such as proton flash and arc therapy …

The upcoming commissioning of the superconducting (SC) continuous wave Helmholtz
linear accelerators first of series cryomodule is going to demand precise alignment of the …

Abstract The High Intensity Proton Accelerator (HIPA) cyclotron at the Paul Scherrer Institut
(PSI) delivers 590 MeV CW proton beam with a maximum power of 1.42 MW. After …

Abstract At PSI (Paul Scherrer Institute), Switzerland, a superconducting cyclotron called
“COMET” delivers proton beam of 250 MeV pulsed at 72.85 MHz for proton radiation …

In hadron therapy beamlines, passive elements are used to reduce the beam energy or to
shape its transverse profile and frequently complement the magnetic transport channel …

The accurate verification of beam parameters is mandatory for treatment safety in particle
therapy, therefore, the systematic uncertainties of the segmented ionization chambers and …
