The dosimetric enhancement of GRID profiles using an external collimator in pencil beam scanning proton therapy

Purpose The radiobiological benefits afforded by spatially fractionated (GRID) radiation therapy pairs well with the dosimetric advantages of proton therapy. Inspired by the emergence of energy‐layer specific collimators in pencil beam scanning (PBS), this work investigates how the spot spacing and...
