Predicting voxel-level dose distributions of single-isocenter volumetric modulated arc therapy treatment plan for multiple brain metastases

Autor: Peng Huang, Jiawen Shang, Zhihui Hu, Zhiqiang Liu, Hui Yan

Publikováno v: Frontiers in Oncology, Vol 14 (2024)

PurposeBrain metastasis is a common, life-threatening neurological problem for patients with cancer. Single-isocenter volumetric modulated arc therapy (VMAT) has been popularly used due to its highly conformal dose and short treatment time. Accurate

Single-isocenter stereotactic radiosurgery for multiple brain metastases: Impact of patient misalignments on target coverage in non-coplanar treatments

Autor: Michael Martin Eder, Michael Reiner, Christian Heinz, Sylvia Garny, Philipp Freislederer, Guillaume Landry, Maximilian Niyazi, Claus Belka, Marco Riboldi

Publikováno v: Zeitschrift für Medizinische Physik, Vol 32, Iss 3, Pp 296-311 (2022)

Frameless single-isocenter non-coplanar stereotactic radiosurgery (SRS) for patients with multiple brain metastases is a treatment at high geometrical complexity. The goal of this study is to analyze the dosimetric impact of non-coplanar image guidan
