Available in PDF, EPUB and Kindle. Book excerpt: The development of intensity-modulated radiotherapy (IMRT) has greatly enhanced the possibilities of shaping the dose distribution. However, because of physical limitations, even with IMRT a certain dose to organs at risk is unavoidable, so in treatment planning often a compromise between different plan criteria has to be found. This thesis presents a new optimization concept that is dedicated to this type of problem. It is based on the fact that there is no single optimal plan, but many so-called Pareto optimal plans, which cannot be improved in one criterion without worsening another. A database with all Pareto optimal plans is generated and the decision which compromise is clinically the best is left to the planner. Because of the higher calculation complexity, the dose calculation of the existing planning system was accelerated by a factor of three through statistical sampling of the calculation matrices. To describe a plan, a vector containing the 'equivalent uniform doses' (EUDs) of each structure is used. Therefore two EUD models were analyzed, the 'max & mean' and the 'generalized mean' model. An algorithm was developed to include the 'generalized mean' model in the plan optimization. At the end of the thesis, the database containing all Pareto optimal solutions of a clinical test case with 1 target volume and 2 organs at risk was generated and visualized. The planner can see at first sight the dependencies of the different plan elements and can decide which plan is clinically the best.

Book Synopsis Multiobjective Optimization in Imrt Treatment Planning by : Lizhen Shao
Download or read book Multiobjective Optimization in Imrt Treatment Planning written by Lizhen Shao and published by LAP Lambert Academic Publishing. This book was released on 2010-07 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of intensity modulated radiation therapy (IMRT) is to kill tumor cells while at the same time protecting the surrounding tissue and organs from the damaging effect of radiation. Given the number of beams and beam directions, beam intensity optimization needs to determine beam intensity profiles that yield the best dose distribution under consideration of clinical and physical constraints. In this book, we first review existing mathematical models and computation methods for the beam intensity optimization problem. Then we formulate the beam intensity optimization problem as a multiobjective linear programme (MOLP) with three objectives. The rest of the book is dedicated to developing methods to solve this large MOLP efficiently and to the application in the beam intensity optimization problem. The book provides the necessary mathmatical foundation of multiobjective optimization to solve multiobjective linear programming problems. It is well suitable to be used as a reference book on multiobjective optimization. Moreover it should also be useful to professionals who may be considering using multiobjective optimization.

Available in PDF, EPUB and Kindle. Book excerpt: Intensity-modulated radiation therapy (IMRT), one of the most important developments in radiation oncology in the past 25 years, involves technology to deliver radiation to tumors in the right location, quantity and time. Unavoidable irradiation of surrounding normal tissues is distributed so as to preserve their function. The achievements and future directions in the field are grouped in the three sections of the book, each suitable for supporting a teaching course. Part 1 contains topical reviews of the basic principles of IMRT, part 2 describes advanced techniques such as image-guided and biologically based approaches, and part 3 focuses on investigation of IMRT to improve outcome at various cancer sites.

This book was released on 2024-07-22 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tackle the most challenging problems in science and engineering with these cutting-edge algorithms Multi-objective optimization problems (MOPs) are those in which more than one objective needs to be optimized simultaneously. As a ubiquitous component of research and engineering projects, these problems are notoriously challenging. In recent years, evolutionary algorithms (EAs) have shown significant promise in their ability to solve MOPs, but challenges remain at the level of large-scale multi-objective optimization problems (LSMOPs), where the number of variables increases and the optimized solution is correspondingly harder to reach. Evolutionary Large-Scale Multi-Objective Optimization and Applications constitutes a systematic overview of EAs and their capacity to tackle LSMOPs. It offers an introduction to both the problem class and the algorithms before delving into some of the cutting-edge algorithms which have been specifically adapted to solving LSMOPs. Deeply engaged with specific applications and alert to the latest developments in the field, it’s a must-read for students and researchers facing these famously complex but crucial optimization problems. The book’s readers will also find: Analysis of multi-optimization problems in fields such as machine learning, network science, vehicle routing, and more Discussion of benchmark problems and performance indicators for LSMOPs Presentation of a new taxonomy of algorithms in the field Evolutionary Large-Scale Multi-Objective Optimization and Applications is ideal for advanced students, researchers, and scientists and engineers facing complex optimization problems.
