In magnetic resonance (MR) guided radiotherapy, the magnetic field-dependent change in
the dose response of ionization chambers is typically included by means of a correction …

A Monte Carlo user code, MCDOSE, has been developed for radiotherapy treatment
planning (RTP) dose calculations. MCDOSE is designed as a dose calculation module …

A novel geometry has been proposed for a hybrid magnetic resonance imaging (MRI)‐linac
system in which a 6 MV linac is mounted on the open end of a biplanar, low field (0.2 T) MRI …

Purpose: The magnetic fields of linac‐MR systems modify the path of contaminant electrons
in photon beams, which alters patient skin dose. To accurately quantify the magnitude of …

With the advent of MR guided radiotherapy the relevance of Monte Carlo radiation transport
simulations in the presence of strong magnetic fields (B-fields) is increasing. While new tests …

Monte Carlo (MC) simulation is commonly considered to be the most accurate dose
calculation method in radiotherapy. However, its efficiency still requires improvement for …

The aim of this project is to extend accurate and patient-specific treatment planning to new
treatment modalities, such as molecular targeted radiation therapy, incorporating previously …

In this work, we investigate a formalism for monitor unit (MU) calculation in Monte Carlo
based treatment planning. By relating MU to dose measured under reference calibration …

In the present work, Monte Carlo (MC) models of electron beams (energies 4, 12 and
18MeV) from an Elekta SL25 medical linear accelerator were simulated using …

For Monte Carlo linac simulations and patient dose calculations, it is important to accurately
determine the phase space parameters of the initial electron beam incident on the target …
