14 de dez. de 2023 · Volumetric Modulated Arc Therapy Craniospinal Irradiation Utilizing a Vertebral Body Sparing Approach: An Alternative Approach to Improve Access and Minimize Toxicity - Advances in Radiation Oncology. Research Letter | Volume 9, ISSUE 3, 101424, March 2024. Download Full Issue.
Volumetric Modulated Arc Therapy (VMAT) was introduced in 2007 and was described as a novel radiation technique that has continuous modulation of MLCs (field shaping), along with the dose rate and gantry speed rotation utilized to deliver highly conformal dose distributions simultaneously, in a minimal time period with reasonable MUs to be ...

Originally proposed as intensity-modulated arc therapy (IMAT) in 1995 as an alternative to tomotherapy, the idea of VMAT is to optimize the treatment plan in many angles, and then sequence it into stacks of apertures at every angle, followed by delivery of the beam with multiple connected arcs.2 VMAT delivers radiation with a multileaf collimato...

1 de out. de 2023 · We hypothesize that VBS-CSI utilizing volumetric modulated arc therapy (VMAT) could also effectively reduce dose to vertebral bodies and surrounding organs-at-risk (OARs), minimizing toxicity for adult patients with LMD and comparing favorably to proton-based CSI.
16 de nov. de 2022 · Volumetric modulated arc therapy (VMAT) is a form of radiation therapy used to treat cancer. During treatment, a machine rotates around your body, sending multiple energy beams of varying strengths to kill cancer cells and destroy tumors. It treats various cancers, including prostate cancer, lung cancer and head and neck cancers ...
2 de nov. de 2018 · VMAT, considered to be similar to IMRT was first described by Yu et al. in 1995. 11 It is capable of delivering radiation therapy with a multi-leaf collimator (MLC) which dynamically alters the shape of the treatment field while the gantry rotates around the patient.
