Single-Isocenter Multiple-Target Stereotactic Radiosurgery: Risk of Compromised Coverage.
PURPOSE To determine the dosimetric effects of rotational errors on target coverage using volumetric modulated arc therapy (VMAT) for multitarget stereotactic radiosurgery (SRS). METHODS AND MATERIALS This retrospective study included 50 SRS cases, each with 2 intracranial planning target volumes (PTVs). Both PTVs were planned for simultaneous treatment to 21 Gy using a single-isocenter, nonc...
متن کاملOptimization Algorithm for Single-Isocenter VMAT Stereotactic Radiosurgery for Multiple Brain Metastases
Objectives: Developing an optimal Stereotactic radiosurgery (SRS) plan for multiple brain metastases can be a labor intensive process. Single-isocenter multi-arc volumetrically modulated arc therapy (VMAT) has been used as an SRS technique, in which a Linear Accelerator (Linac) delivers targeted radiation along multiple arc angles as it rotates around the isocenter. Standardized arc angles with...

متن کاملRADIATION PROTECTION OF PATIENT DURING STEREOTACTIC RADIOSURGERY. Part I: Single isocenter phantom measurements
Radiation dose to organs outside the radiotherapy treatment field can be significant and clinical interest. Therefore, in order to estimate peripheral doses (PD) during the stereotactic radiosurgery treatment with Leksell Gamma Knife for single isocenter treatment technique in particular as a part of the method can be described the all plan treatment in general. Knowledge of PD can be used effe...
متن کاملOptimization of multiple-isocenter treatment planning for linac-based stereotactic radiosurgery.
OBJECTIVE Computer-assisted treatment planning for linac-based radiosurgery is still an open research problem, especially for multiple-isocenter procedures, primarily due to its high complexity and computational requirements. This paper focuses on the optimization of multiple-isocenter treatment planning for linac systems, and addresses several important issues associated with multiple isocente...
