Including fiducial markers in radiation therapy planning to facilitate real-time position monitoring during treatment delivery |
摘要 |
An inverse planning method that is capable of controlling the appearance of the implanted fiducial(s) in segmented IMRT fields for cine MV or combined MV/kV image-guided IMRT is provided. The method for radiation treatment includes computing a radiation treatment plan and delivering beams to a target in accordance with the radiation treatment plan, where computing the radiation treatment plan includes introducing a penalty in an inverse planning objective function optimization calculation to discourage or avoid blockage of one or more fiducials in optimized multi-leaf collimator (MLC) apertures. |

1. A method for radiation treatment comprising computing a radiation treatment plan and delivering beams to a target in accordance with said radiation treatment plan, wherein computing said radiation treatment plan comprises introducing a penalty in an inverse planning objective function optimization calculation to discourage or avoid blockage of one or more fiducials in optimized multi-leaf collimator (MLC) apertures, wherein for a given gantry angle θ and phase p, a weight wθp is provided for a phase-segment, wherein said radiation treatment plan optimizes shapes and weights of all said MLC aperture shapes. |
