Methods and systems for automatic radiotherapy treatment planning |
| abstract |
Systems and methods for improved radiation treatment planning can employ hierarchical constrained optimization with relaxed constraints also referred to herein after as expedited hierarchical constrained optimization (ECHO). The systems and methods described herein employ a combination of constrained optimization and a correction loop involving unconstrained optimization to enhance the speed and efficiency of the radiation treatment planning process and improve the accuracy and quality of resulting radiation treatment plans. The use of a hierarchical constrained optimization approach leads to less complex and faster to solve optimization problems. The correction loop allows for compensating for optimization error associated with the sequence of constrained optimizations by incorporating such error in an unconstrained optimization. Hard and soft dose volume constraints can be efficiently incorporated. |
