Popis:	In Magnetic Resonance-Linac (MR-Linac) dosimetry formalisms, a new correction factor, kThis study aims to develop and implement a Monte Carlo (MC)-based framework for the determination of kPhase space files for three irradiation fields of the ELEKTA Unity 1.5 T/7 MV flattening-filter-free MR-Linac were provided by the manufacturer and used as source models throughout this study. Twelve ionization chambers (three farmer-type and nine small-cavity detectors, from three manufacturers) were modeled (including their dead volume) using the EGSnrc MC code package. kFor both parallel (to the magnetic field) orientations, kFor the 10 × 10 cm
