GPU-based ultra-fast dose calculation using a finite size pencil beam model.
Online adaptive radiation therapy (ART) is an attractive concept that promises the ability to deliver an optimal treatment in response to the inter-fraction variability in patient anatomy. However, it has yet to be realized due to technical limitations. Fast dose deposit coefficient calculation is a critical component of the online planning process that is required for plan optimization of inte...
متن کاملEvaluation of uncertainty predictions and dose output for model-based dose calculations for megavoltage photon beams.
In many radiotherapy clinics an independent verification of the number of monitor units (MU) used to deliver the prescribed dose to the target volume is performed prior to the treatment start. Traditionally this has been done by using methods mainly based on empirical factors which, at least to some extent, try to separate the influence from input parameters such as field size, depth, distance,...
متن کاملFast Pencil Beam Dose Calculation for Proton Therapy Using a Double-Gaussian Beam Model
The highly conformal dose distributions produced by scanned proton pencil beams (PBs) are more sensitive to motion and anatomical changes than those produced by conventional radiotherapy. The ability to calculate the dose in real-time as it is being delivered would enable, for example, online dose monitoring, and is therefore highly desirable. We have previously described an implementation of a...
متن کاملPoint dose calculations using an analytical pencil beam kernel for IMRT plan checking.
A method to verify the monitor units for a treatment plan is to calculate point doses, possibly at the isocentre, by using a simple calculation method. This verification is recommended to find mistakes in the treatment plan. Treatment plans for intensity modulated radiation therapy are no exception. The method should employ a simple physical model and a dose calculation algorithm, which is diff...
متن کاملA GPU-Based Pencil Beam Algorithm for Dose Calculations in Proton Radiation Therapy
Recent developments in radiation therapy have been focused on applications of charged particles, especially—protons. Proton therapy can allow higher dose conformality compared to conventional radiation therapy. Dose calculations have an integral role in the successful application of proton therapy. Over the years several dose calculation methods have been proposed in proton therapy. A common ch...
