A Collimator Setting Optimization Algorithm for Dual-Arc Volumetric Modulated Arc Therapy in Pancreas Stereotactic Body Radiation Therapy.
(Technology in cancer research & treatment, 2019-01)PURPOSE:To optimize collimator setting to improve dosimetric quality of pancreas volumetric modulated arc therapy plan for stereotactic body radiation therapy. MATERIALS AND METHODS:Fifty-five volumetric modulated arc therapy ... -
Adaptive stereotactic body radiation therapy planning for lung cancer.
(Int J Radiat Oncol Biol Phys, 2013-09-01)PURPOSE: To investigate the dosimetric effects of adaptive planning on lung stereotactic body radiation therapy (SBRT). METHODS AND MATERIALS: Forty of 66 consecutive lung SBRT patients were selected for a retrospective ... -
Dynamic Conformal Arc Informed Volumetric Modulated Arc Therapy for Stereotactic Radiosurgery
(2019)Purpose: Linear accelerator-based Stereotactic Radiosurgery (SRS) is often performed using either dynamic conformal arcs or VMAT. For multifocal disease, multifocal conformal arc techniques can struggle to deliver the desired ... -
Evaluation of dosimetric uncertainty caused by MR geometric distortion in MRI-based liver SBRT treatment planning.
(Journal of applied clinical medical physics, 2019-02)PURPOSE:MRI-based treatment planning is a promising technique for liver stereotactic-body radiation therapy (SBRT) treatment planning to improve target volume delineation and reduce radiation dose to normal tissues. MR geometric ... -
Hippocampal Avoidance in Multi-Target Radiosurgery
(2021)Brain metastases can occur in 20%-40% of cancer patients. Single isocenter multi-target (SIMT) radiosurgery planned with volumetric modulated arc therapy (VMAT) is a method of treating multiple brain metastases simultaneously. ... -
Impact of collimator leaf width and treatment technique on stereotactic radiosurgery and radiotherapy plans for intra- and extracranial lesions.
(Radiation oncology (London, England), 2009-01-21)BACKGROUND: This study evaluated the dosimetric impact of various treatment techniques as well as collimator leaf width (2.5 vs 5 mm) for three groups of tumors -- spine tumors, brain tumors abutting the brainstem, and liver ... -
Knowledge Modeling for The Outcome of Brain Stereotactic Radiosurgery
(2016)Purpose: To build a model that will predict the survival time for patients that were treated with stereotactic radiosurgery for brain metastases using support vector machine (SVM) regression. Methods and Materials: This ... -
Physics and Treatment Planning Considerations for Multifocal Radiosurgery and SBRT
(2017)Purpose:A new development in linac-based intracranial stereotactic radiosurgery (SRS) and extracranial stereotactic body radiation therapy (SBRT) is treatment of multiple targets using single isocenter volumetric modulated ...
