Download or read book Standardization and Automation for Radiotherapy Treatment Planning System Commissioning written by Amelia Platt Wexler and published by . This book was released on 2016 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treatment planning system (TPS) commissioning is time consuming, labor intensive and error prone. Guidelines exist for commissioning procedures yet media and reports expose harmful dosimetric inaccuracies due to human error. This dissertation intended to develop a model for reducing errors and improving efficiency in the TPS commissioning process. This project aimed to 1) evaluate the level of risk for current published guidelines for TPS commissioning and determine where errors could be reduced 2) design an automated commissioning test suite (ACTS) that incorporates recommended tests from multiple reports and task groups 3) evaluate the level of risk for the proposed automated commissioning process (ACP) that uses automation and standards: preloaded/pre-modeled beam data, preloaded digital phantoms, ACTS, application program interface (API), validation measurements using an Electronic Portal Imaging Device (EPID) for improved benchmarking to cloud storage for access to data and ongoing QA 4) compare associated risk between manual and automated TPS commissioning procedures 5) create proof of concept script and conduct testing. The data shows that there are fewer failure modes and lower associated risk when TPS commissioning tests are automated. The presented work suggests that errors and risks may be reduced by applying standardization and automation to the TPS commissioning process.
Download or read book Record and Verify Systems for Radiation Treatment of Cancer written by International Atomic Energy Agency and published by IAEA Human Health Reports. This book was released on 2013 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication serves as a useful guide for medical physicists in radiation oncology, radiation oncologists and radiation therapists, ensuring accuracy, safety and quality in radiation therapy. Record and verify systems (RVSs) were developed to reduce the risk of treatment errors in radiation oncology. These have recently evolved into complete radiotherapy information management systems that interface with imaging systems, treatment planning computers, and treatment delivery systems. To function as intended, RVSs must be subject to a comprehensive quality assurance (QA) program. This publication provides practical guidelines for a comprehensive QA programme and its implementation. It describes the QA program, including acceptance tests and the commissioning process that should be used in conjunction with the installation of a new RVS. It is also highlighted that some of the tests performed at installation must be repeated regularly as part of the periodic quality control checks.

Download or read book Advanced Computing and Automation in Radiation Therapy Treatment Planning written by Henry Wang and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: \Prefacesection{Abstract} The Boltzmann transport equation describes the macroscopic behavior of radiation particles such as neutrons, photons, and electrons as they travel through and interact with matter. The widely known Monte Carlo (MC) method is a general approach to obtaining open form solutions to the linearized Boltzmann transport equation. Monte Carlo algorithm is thte most accurate way to predict how dose is delivered inside a patient. However, the computation time inhibits its routine use in the clinic. For a patient, MC carlo simulation takes anywhere from 10 hours to several days. In this dissertation, we use the state-of-the-art cloud computing technology to accelerate Monte Carlo methods. The approach is evaluated for pencil beams and broad beams of high-energy electrons and photons. The cloud-based Monte Carlo simulation is compared to single-threaded implementation and demonstrates a 47x speed up. Current clinical treatment planning requires multiple trial-and-error adjustments of system model parameters. Producing a treatment plan is time consuming. A team of physician, dosimetrist, and physicist manually adjust parameters in a commercial planning environment. In this dissertation, an autonomous treatment planning technique is implemented in a clinical platform. An outer-loop decision function interacts on-the-fly with an inner-loop clinical treatment planning system (TPS). The approach is applied to 3 head and neck volumetric modulated arc therapy (VMAT) cases and one prostate intensity-modulated radiation therapy (IMRT) case. A strategy of using population-based prior patient data was explored. An upper and lower bound for the dose-volume segments are derived from a group of previously treated patients. The bounds are then used for new case to provide a dosimetric range for acceptability. An heuristic algorithm adjusts the constraints for the optimization using a stochastic approach. Rather than setting a deterministic value for each dose-volume segments, the constraint is changed during each iteration of the outer-loop optimization. The proposed algorithm is applied to a head and neck VMAT case and a prostate IMRT case on a clinical treatment planning system. Results obtained show a comparable dose volume histogram (DVH) compared to manual planning.

Download or read book Automating Intensity Modulated Radiation Therapy Treatment Planning by Using Hierarchical Optimization written by Paras Babu Tiwari and published by . This book was released on 2015 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intensity modulated radiation therapy (IMRT) optimizes the beam's intensity to deliver the prescribed dose to the target while minimizing the radiation exposure to normal structures. The IMRT optimization is a complex optimization problem because of the multiple conflicting objectives in it. Due to the complexity of the optimization, the IMRT treatment planning is still a trial and error process. Hierarchical optimization was proposed to automate the treatment planning process, but its potential has not been demonstrated in a clinical setting. Moreover, hierarchical optimization is slower than the traditional optimization. The dissertation studied a sampling algorithm to reduce the hierarchical optimization time, customized an open source optimization solver to solve the nonlinear optimization formulation and demonstrated the potential of hierarchical optimization to automate the treatment planning process in a clinical setting. We generated the treatment plans of 31 prostate patients by hierarchical optimization using the same criteria as used by planners to prepare the treatment plans at Memorial Sloan Kettering Cancer Center. We found that hierarchical optimization produced the same or better treatment plans than that produced by a planner using the Eclipse treatment planning system. Therefore, the dissertation demonstrated that hierarchical optimization could automate the treatment planning process and shift the paradigm of the treatment planning from manual trial and error to an ideal automated process.
