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 ... -
Benchmarking Flattening Filter-Free Photons for IMRT/VMAT using TG119
(2014)Since the publication of TG119 in 2009, new techniques have emerged in the field of radiation therapy including VMAT (Volumetric Arc Therapy) and the FFF (Flattening Filter Free) mode in Varian linear accelerators. Our goal ... -
Development and Testing of An Automatic Lung IMRT Planning Algorithm
(2016)Knowledge-based radiation treatment is an emerging concept in radiotherapy. Itmainly refers to the technique that can guide or automate treatment planning inclinic by learning from prior knowledge. Dierent models are developed ... -
Dose-Guided Automatic IMRT Planning: A Feasibility Study
(2014)Purpose: To develop and evaluate an automatic IMRT planning technique for prostate cancer utilizing prior expert plan's dose distribution as guidance.Methods and Materials: In this study, the anatomical information of prostate ... -
Impact of Esophageal Motion on Dosimetry and Toxicity With Thoracic Radiation Therapy.
(Technology in cancer research & treatment, 2019-01)PURPOSE:To investigate the impact of intra- and inter-fractional esophageal motion on dosimetry and observed toxicity in a phase I dose escalation study of accelerated radiotherapy with concurrent chemotherapy for locally ... -
Investigation of AP/PA Recumbent Technique for Total Body Irradiation
(2020)Purpose: Total body irradiation (TBI) is to deplete patient’s bone marrow and suppress the immune system by delivering uniform dose to patient’s whole body with a relatively low dose rate. The widely used total body irradiation ... -
Knowledge-Based IMRT Treatment Planning for Bilateral Head and Neck Cancer
(2013)Intensity-modulated radiotherapy (IMRT) remains the standard of care for external beam radiation therapy for head and neck cancers. Planning for IMRT requires a trial-and-error approach that is completely dependent on planner ... -
Knowledge-Based IMRT Treatment Planning for Prostate Cancer: Experience with 101 cases from Duke Clinic
(2012)Intensity-modulated radiotherapy (IMRT) has become an effective tool for cancer treatment with radiation. However, even expert radiation planners still need to spend a substantial amount of time, approximately 4 hours, manually ... -
Multi-Case Knowledge-Based IMRT Treatment Planning in Head and Neck Cancer
(2014)<bold>Purpose:</bold> HNC IMRT treatment planning is a challenging process that relies heavily on the planner's experience. Previously, we used the single, best match from a library of manually planned cases to ... -
The Need for Adaptive Intensity Modulated Radiotherapy Replanning in Head-and-Neck Patients with Anatomical Changes During Treatment
(2013)AbstractPurpose: The aim of this study is to quantify the effectiveness of adaptive radiation therapy (ART) when anatomical changes to the tumor and/or the organs are observed for head and neck patients during the course ... -
Toward Clinically Intuitive Quality Assurance
(2012)The need for clinically intuitive quality assurance procedures has been well-documented; current QA methods such as 2D gamma analysis have been shown (Nelms, Zhen et al. 2011) to be inadequate in predicting clinically relevant ... -
Treatment-Induced Dosimetric/Volumetric Changes During the Course of Radiotherapy for Lung Cancer
(2012)Purpose: The goal of this study is to investigate the necessity of adaptive radiation therapy (ART) for lung cancer patients treated with intensity modulated radiation therapy (IMRT) by quantifying the change in the tumor ...
