A Monte Carlo (MC) code (VMCpro) for treatment planning in proton beam therapy of cancer
is introduced. It is based on ideas of the Voxel Monte Carlo algorithm for photons and …

The main advantages of proton therapy are the reduced total energy deposited in the patient
as compared to photon techniques and the finite range of the proton beam. The latter adds …

Density heterogeneities can have a profound effect on dose distributions for proton therapy.
Although analytical calculations in homogeneous media are relatively straightforward, the …

Contemporary treatment planning systems for proton radiotherapy typically use analytical
pencil-beam algorithms—which require a comprehensive set of configuration data—to …

The prescribed dose in radiation therapy has to be converted into machine monitor units for
patient treatment. This is done routinely for each spread-out Bragg peak (SOBP) field either …

The purpose of this study was to assess the possibility of introducing site-specific range
margins to replace current generic margins in proton therapy. Further, the goal was to study …

To evaluate the effect of approximations in clinical analytical calculations performed by a
treatment planning system (TPS) on dosimetric indices in intensity modulated proton …

Dose in radiation therapy is traditionally reported as the water-equivalent dose, or dose to
water. Monte Carlo dose calculations report dose to medium and thus a methodology is …

This paper presents the main results of a Monte Carlo simulation describing the Orsay
Proton Therapy Center (CPO) beam line. The project aimed to obtain a prediction of the …

It is important for proton therapy to calculate dose distributions accurately in treatment
planning. Dose calculations in the body for treatment planning are converted to dose …
