Optimization 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 کاملSingle-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 کاملThe spatial accuracy of two frameless, linear accelerator‐based systems for single‐isocenter, multitarget cranial radiosurgery
Single-isocenter, multitarget cranial stereotactic radiosurgery (SRS) is more efficient than using an isocenter for each target, but spatial positioning uncertainties can be magnified at locations away from the isocenter. This study reports on the spatial accuracy of two frameless, linac-based SRS systems for multitarget, single-isocenter SRS as a function of distance from the isocenter. One sy...
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...
