Volumetric modulated arc planning for lung stereotactic body radiotherapy using conventional and unflattened photon beams: a dosimetric comparison with 3D technique

Radiation Oncology, 2011
Purpose Frequently, three-dimensional (3D) conformal beams are used in lung cancer stereotactic body radiotherapy (SBRT). Recently, volumetric modulated arc therapy (VMAT) was introduced as a new treatment modality. VMAT techniques shorten delivery time,

Volumetric-modulated arc therapy (VMAT) versus 3D-conformal radiation therapy in supra-diaphragmatic Hodgkin’s Lymphoma with mediastinal involvement: A dosimetric comparison

Journal of the Egyptian National Cancer Institute, 2016
Purpose: To compare volumetric-modulated arc therapy (VMAT) with 3D-conformal radiation therapy (3D-CRT) mediastinal irradiation for stage I–II supra-diaphragmatic Hodgkin’s Lymphoma (HL). Patients and methods: Eleven patients were planned for RT after 4–

Spine SBRT using VMAT

Journal of Physics: Conference Series, 2017
Metastases of the spinal column are common amongst cancer patients with approximately 18,000 new cases in North America each year that require urgent treatment. Historically radiation therapy doses have been limited due to the proximity of the spinal cord.
