Monte Carlo Dose Algorithm

Conventional dose calculation algorithms, such as Pencil Beam are proven effective for tumors located in homogeneous regions with similar tissue consistency such as the brain. However, these algorithms tend to overestimate the dose distribution in extracranial regions such as in the lung and head and neck regions where large inhomogeneities exist. Due to the inconsistencies seen in current calculation methods for extracranial treatments and the need for the creation and integration of improved calculation methods into treatmen software. Figure 1: The Monte Carlo (XVMC) Dose Algorithm Algorithms (left) show discretization artifacts. iPlan RT Dose with Monte Carlo from Brainlab has been developed in order to compensate for this under dosage in extracranial calculations and improve radiation treatment planning accuracy for clinical practice. The advanced dose calculation solution from Brain method of modelling the transport of radiation through the beam collimation system and through human tissue. Monte Carlo requires a 3 to create an internal model of the patien emitted by a medical linear accelerator. The present implementation is designed to model photon radiation. It can be used to calculate dose for conformal treatments including conformal beam, IMRT, static and dynamic arc and HybridArc treatment modalities. The MLC and patient models are created using interaction parameter tabulations from the National Institute of Standards and Technology (NIST) of the USA and the International Commission on Radiation Units and Measurements (ICRU). Studies have shown that Monte Carlo is more accurate for arc and dynamic IMRT treatments since the MC algorithm simulates gantry rotations and dynamic leaf movements continuously and not in discrete steps as with other algorithms. For these treatments the Monte Carlo calculation might even be faster than the pencil beam. software, Monte Carlo is designed to provide additional dose planning choice for the cl more precise radiation delivery, research has led to (right) simulates rotational treatments continuously lab is based on the Monte Carlo (MC) -dimensional CT-scan of the patient's tissue t and to calculate the dose distribution of the radiation Multileaf Collimator (MLC) As an integral part of the iPlan RT Dose tumors diagnosed in
