A Collimator Setting Optimization Algorithm for Dual-arc Volumetric Modulated Arc Therapy in Pancreas Stereotactic Body Radiation Therapy
(2019)Purpose: To develop an automatic collimator setting optimization algorithm to improve dosimetric quality of pancreas Volumetric Modulated Arc Therapy (VMAT) plans for Stereotactic Body Radiation Therapy (SBRT). Methods: ... -
A current perspective on stereotactic body radiation therapy for pancreatic cancer.
(Onco Targets Ther, 2016)Pancreatic cancer is a formidable malignancy with poor outcomes. The majority of patients are unable to undergo resection, which remains the only potentially curative treatment option. The management of locally advanced ... -
Application of TG-218 to SRS and SBRT Pre-Treatment Patient Specific QA
(2020)AbstractPurpose: Updated recommendations for pre-treatment QA of patient-specific intensity modulated radiation therapy (IMRT) and Volumetric modulated arc therapy (VMAT) quality assurance (QA) were recently published by ... -
CBCT image enhancement for improving accuracy of radiomics analysis and soft tissue target localization
(2023)Cone-beam computed tomography (CBCT) is one of the most commonly used image modalities in radiation therapy. It provides valuable information for target localization and outcome prediction throughout treatment courses. However, ... -
Fluence Map Prediction Using Deep Learning Models - Direct Plan Generation for Pancreas Stereotactic Body Radiation Therapy.
(Frontiers in artificial intelligence, 2020-01)Purpose: Treatment planning for pancreas stereotactic body radiation therapy (SBRT) is a difficult and time-consuming task. In this study, we aim to develop a novel deep learning framework to generate clinical-quality plans ... -
Investigation of Patient Positioning Accuracy in Lung Stereotactic Body Radiation Therapy
(2013)Purpose: It has been shown that patients' irregular breathing can cause variation in the delineation of the internal target volume (ITV) and affect the accuracy of four dimensional computed tomography (4DCT) and cone-beam ... -
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 ... -
Pre-treatment Radiomics Models for Clinical Outcomes in Early-stage Non-Small Cell Lung Cancer (NSCLC)
(2021)Lung cancer in accounts for 13% of all new cancer diagnoses and is the leading cause of cancer mortality in the United States (Bogart, 2017, Howlader, 2020). Non-small cell lung cancer (NSCLC) in particular, accounts for ... -
Radiomic feature variability on cone-beam CT images for lung SBRT
(2018)This study aims to (1) investigate methodology for harmonization of radiomics features between planning CT and on-board CBCT and establish a workflow to harmonize images taken from different scanning protocols and over the ... -
Spine SBRT With Halcyon™: Plan Quality, Modulation Complexity, Delivery Accuracy, and Speed.
(Frontiers in Oncology, 2019-01)Purpose: Spine SBRT requires treatment plans with steep dose gradients and tight limits to the cord maximal dose. A new dual-layer staggered 1-cm MLC in Halcyon™ treatment platform has improved leakage, speed, and DLG compared ... -
Tumor Motion Analysis Using Cine-MV in Lung Stereotatic Radiation Therapy
(2012)Probabilistic planning is an evolving approach for tumor motion management in which reproducibility of probability distribution function (PDF) of tumor motion is critical yet unclear. Aim of the first study is to evaluate ... -
Using Genetically Engineered Mouse Models to Dissect the Critical Cellular Target of Radiation Therapy
(2018)Approximately half of all cancer patients will receive radiation as part of their treatment regimen in either a palliative or curative setting. Conventionally, radiation therapy has been administered to patients in small ...
