Automatic Specific Absorption Rate (SAR) Prediction for Hyperthermia Treatment Planning (HTP) Using Deep Learning Method

Authors: Yankun Lang, Lei Ren, Dario B. Rodrigues

Affiliation: University of Maryland School of Medicine, Department of Radiation Oncology, University of Maryland School of Medicine

Abstract Preview: Purpose:
HTP of microwave (MW) phased-array systems determine MW antenna settings to maximize energy absorption (SAR in W/kg) in tumor. Conventional HTP algorithms calculate SAR based on electromag...

Development of a Robust 3D-Ultrasound (3DUS) Quality Assurance (QA) Framework for a Real-Time Needle-Tracking System in HDR GYN Brachytherapy

Authors: Diandra Ayala-Peacock, Lindsey Hendricks Bloom, Oana I. Craciunescu, Julie A. Raffi, Megan K. Russ, Ryan Sanford, Rajesh Venkarataman

Affiliation: Clinical Imaging Physics Group, Department of Radiology, Duke University Health System, Duke University Medical Center, Duke University, Eigen Health, Duke Univesity

Abstract Preview: Purpose: To establish a robust QA framework to characterize and ensure accuracy, reliability, and reusability of a transrectal ultrasound (TRUS)-based needle tracking system (NTS) for clinical HDR GYN...

Evaluating LiF:Mg,Ti TLD Reliability at Body Temperature for Long-Term Dose Monitoring

Authors: Larry A. DeWerd, Keith A. Kunugi, Autumn Rasmussen

Affiliation: Department of Medical Physics, School of Medicine and Public Health, University of Wisconsin - Madison

Abstract Preview: Purpose: Ensuring the validity of the thermoluminescent dosimeter (TLD) response requires verifying that signal fading—defined by a reduction in stored signal—is well-known and corrected for under the...

Investigating the Use of a DWI Phantom for Routine QA of an MR-Linac at Room Temperature

Authors: Nicholas Carlson, Joel J. St-Aubin

Affiliation: University of Iowa Hospitals and Clinics, University of Iowa

Abstract Preview: Purpose: To establish baselines metrics and determine longitudinal accuracy and reproducibility of Diffusion-Weighted Imaging (DWI) and Apparent Diffusion Coefficient (ADC) values for a 1.5T Elekta Un...

Multi-Center Diffusion-Weighted MRI Validation for 0.35T MR-Linac: A Repeatability and Reproducibility Study

Authors: Tess Armstrong, Nema Bassiri, Alonso N. Gutierrez, Michael Kasper, Natalia Lutsik, Eric Mellon, Kathryn E. Mittauer, Siamak P. Nejad-Davarani, Shyam Pokharel, Suresh Rana, Hui Wang, Joseph Weygand

Affiliation: Department of Radiation Oncology and Applied Science, Dartmouth Health, Miami Cancer Institute, Baptist Health South Florida, ViewRay, Inc., Miami Cancer Institute, Lynn Cancer Institute, Boca Raton Regional Hospital, Baptist Health South Florida, Department of Radiation Oncology, University of Miami

Abstract Preview: Purpose: Radiation treatments on the MR-linac (MRL) enable daily acquisition of anatomical and physiological images for adaptive treatment planning. The apparent diffusion coefficient (ADC) estimated ...

On the Development and Commissioning of an in-Vivo Dosimetry Program Using Small Pieces of Gafchromic Film

Authors: Slade J. Klawikowski, Natalya V. Morrow, Haidy G. Nasief, Eric S. Paulson, An Tai, Hualiang Zhong

Affiliation: Department of Radiation Oncology, Medical College of Wisconsin

Abstract Preview: Purpose: Gafchromic film is commonly used for quality assurance in SRS/SBRT. However, its application in low-dose measurements, such as monitoring doses on cardiac implantable electronic devices—where...
