A Comparison of on-Isocenter Vs Off-Isocenter Planning for Lung SBRT on the Viewray Mridian

Authors: Nebi Demez, Shyam Pokharel, Suresh Rana, Lauren A. Rigsby, Tino Romaguera, Nishan Shrestha

Affiliation: Lynn Cancer Institute, Boca Raton Regional Hospital, Baptist Health South Florida

Abstract Preview: Purpose: Treatment plans on the ViewRay MRIdian are often planned with the target placed off isocenter due to the proximity of the bore to the patient, allowing for limited shifts. This is especially ...

Creation of Customized Workflows in a New Surface-Guided Radiation Therapy (SGRT) System

Authors: Sorour Hosseini, YuHuei Jessica Huang, Jeremy Kunz, Nicholas Pierre Nelson, Ryan G. Price, Prema Rassiah, Hui Zhao

Affiliation: University of Utah, Department of Radiation Oncology, Huntsman Cancer Institute, University of Utah

Abstract Preview: Purpose: To investigate the feasibility and clinical implications of creating customized workflows in a new SGRT system: LUNA 3D (LAP, Florida).
Methods: Three clinical SGRT workflows were designed...

Development and Clinical Validation of a Tissue Maximum Ratio (TMR)-Based Monitor Units Second Check Script for Dynamic Conformal-Based Hyperarc Brain Radiosurgery Plans Via Scatter Correction Factors

Authors: Jacob Gooslin, Ellis Lee Johnson, Damodar Pokhrel

Affiliation: University of Kentucky, Department of Radiation Medicine, University of Kentucky, University of Kentucky, Radiation Medicine

Abstract Preview: Purpose: HyperArc radiosurgery permits treatment of multiple brain lesions using a single-isocenter improving treatment planning efficiency and workflow. A key stereotactic planning aspect is an indep...

Feasibility of Using a Dynamic-Platform with High-Resolution Patient-Specific QA Device for Periodic and Patient-Specific-QA in Respiratory-Gated Radiotherapy Lung SBRT Treatment

Authors: Tae Kyu Lee

Affiliation: Allina Health

Abstract Preview: Purpose: To assess the feasibility of a dynamic-platform integrated with high-resolution patient-specific-quality-assurance (PSQ device for periodic quality assurance (PQA) and PSQA in respiratory-gat...

Investigation of Triggered Imaging and Auto Beam Hold Using a Dynamic Thorax Phantom for Intra-Fraction Motion Management

Authors: Liu Hong, Zhong Su

Affiliation: University of Arkansas for Medical Sciences, Department of Radiation Oncology, University of Arkansas for Medical Sciences (UAMS)

Abstract Preview: Purpose: During treatment delivery on TrueBeam platform 2.7, Triggered Imaging (TI) enables kV images acquisition at regular intervals and Auto Beam Hold (ABH) provides beam pausing if the target is m...

Planning Study of Spatially Fractionated Radiotherapy (SFRT) for Treating Recurrent Glioblastoma Multiforme (GBM)

Authors: Hyunuk Jung, Fiona Li, Brian Marples, Michael Milano, Sean M. Tanny, Dandan Zheng, Yuwei Zhou

Affiliation: Department of Radiation Oncology, University of Rochester, University of Rochester Medical Center, University of Rochester

Abstract Preview: Purpose:
Recurrent GBM remains one of the most challenging cancers, with limited treatment options. We investigated potential planning parameters of SFRT, a novel radiotherapy technique that delive...

Authors: Yussuf A. Abdelal, Junguo Bian, Michael Delafuente, Sebastien A. Gros, Hyejoo Kang, Luke Layman, M Mahesh, John C. Roeske

Affiliation: Department of Radiology and Medical Imaging, Stritch School of Medicine, Loyola University Medical Center, Department of Radiation Oncology, Stritch School of Medicine, Loyola University Chicago, Johns Hopkins Univ

Abstract Preview: Purpose: This study evaluates the feasibility of optimizing 4DCBCT imaging protocols for gated lung SBRT, by reducing dose while maintaining the image quality required for accurate patient alignment.<...

Quantitative 3D Surface Mapping of Cherenkov Images for Real-Time Beam Deviation Detection in Radiotherapy

Authors: Petr Bruza, Alexander Geiersbach, David J. Gladstone

Affiliation: Thayer School of Engineering, Dartmouth College

Abstract Preview: Purpose: Cherenkov images are two-dimensional projections of the surface light emissions, and lack spatial information about the radiotherapy beam delivery. We implement the first fusion of Cherenkov ...
