Influence of different dose calculation algorithms on the estimate of NTCP for lung complications
Due to limitations and uncertainties in dose calculation algorithms, different algorithms can predict different dose distributions and dose-volume histograms for the same treatment. This can be a problem when estimating the normal tissue complication probability (NTCP) for patient-specific dose distributions. Published NTCP model parameters are often derived for a different dose calculation alg...
متن کاملTU-E-BRB-02: A Decision Support Tool for SBRT Planning Using a Searchable DVH Database.
PURPOSE Develop a decision support tool that aids dosimetrists, physicians, and physicists in assessing and improving plan quality through comparison to plans previously used in similar clinical situations. METHODS Software was developed to capture and store DVHs and other clinically relevant treatment plan characteristics in a database. In addition to the plan DVH, the database contains a to...
متن کاملA free user friendly program for evaluation of radiotherapy plans based on different dose response models
Introduction: Radiotherapy (RT) plan evaluation using dose response models has become a feasible approach in routine clinical practice. Although there are several tools for this task, they suffer from limitations including number of different dose response models and parameters. In the present study, we aimed to develop a free program for RT plan evaluation based on a variety ...
متن کاملDoes intensity modulation increase target dose calculation errors of conventional algorithms for lung SBRT?
PURPOSE Conventional dose algorithms (Type A and Type B) for lung SBRT can display considerable target dose errors compared to Type-C algorithms. Intensity-modulated techniques (IMRT/VMAT) are increasingly being utilized for lung SBRT. Therefore, our study aimed to assess whether intensity modulation increased target dose calculation errors by conventional algorithms over conformal techniques. ...
