Há 5 dias · Volumetric modulated arc therapy (VMAT) has allowed for dose escalation and a decrease in radiation-induced toxicities for a variety of treatment sites, including spinal metastases. This article will compare the dosimetric impacts on normal lung tissue in patients treated with both VMAT and conventional treatment to the thoracic spine and determine if any significant difference exists among ...
Há 1 dia · This study explores the feasibility of using the LuSy dosimeter, an in-house developed plastic scintillator dosimeter for dose verification across various radiotherapy techniques, including conformal radiotherapy (CRT), intensity-modulated radiation therapy (IMRT), volumetric-modulated arc therapy (VMAT), and stereotactic radiosurgery (SRS).
Há 2 dias · Intensity modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) are commonly used for the management of PGCs, currently replacing 3D-conformal technique (3D-CRT). 9,10 However, acute and late radiation-related toxicities are still frequent.
Há 5 dias · Modern radiotherapy machines offer a new modality, like flattening filter-free beam (FFF), which is used especially in stereotactic body radiation therapy (SBRT) to reduce treatment time. The remaining volume at risk (RVR) is known as undefined normal tissue, and assists in evaluating late effects such as carcinogenesis. This study aimed to compare the effects of flattening and un-flattened ...
Há 3 dias · Volumetric modulated arc therapy (VMAT) is a radiation technique introduced in 2007 which can achieve highly conformal dose distributions on target volume coverage and sparing of normal tissues. The specificity of this technique is to modify three parameters during the treatment.
Há 15 horas · Offering enhanced accuracy and reduced treatment times, RapidArc™ delivers highly conformal doses of radiation through complete 360-degree rotation and speed variations of the linear accelerator gantry, enabling the Linac to provide Volumetric Modulated Arc Therapy (VMAT) – RapidArc patented technology of Varian.
Há 3 dias · Positioning of the patient, coordination with therapist. As we know, the medical physicist’s goal is to deliver a high dosage of radiation to a specified volume in a succession of defined fractions. High repeatability of the patient’s posture is required to ensure the efficacy of the therapy and the patient’s safety.
