A Dosimetric Study of Misconnection to Unloaded Needles in Interstitial HDR Brachytherapy

Authors: Shifeng Chen, Mariana Guerrero, Brian A. Hrycushko, Kai Huang, Kai Jiang, Narottam Lamichhane, Paul M. Medin, Elizabeth Nichols

Affiliation: Department of Radiation Oncology, UT Southwestern Medical Center, University of Maryland School of Medicine, Department of Radiation Oncology, University of Maryland School of Medicine, Department of Radiation Oncology, University of Maryland Medical Center

Abstract Preview: Purpose: Unloaded needle catheters, if not handled properly, pose a risk for channel misconnection in interstitial high dose rate (iHDR) brachytherapy. This study aims to investigate the dosimetric im...

A Method for Forward Planning with the Venezia HDR Applicator

Authors: Timothy J Allen, David A. Sterling

Affiliation: University of Minnesota Physicians, Department of Radiation Oncology, University of Minnesota, Minneapolis

Abstract Preview: Purpose: Treatment planning for the Venezia HDR brachytherapy applicator is often performed using inverse planning tools such as IPSA or HIPO. However, there are planners who are either unfamiliar wit...

AI Auto-Contouring for CT-Based High-Dose-Rate Interstitial Brachytherapy of Cervical Cancer: Implications for Organ-at-Risk (OAR) Contouring and Dosimetric Analysis

Authors: Indrin J. Chetty, Jing Cui, Mitchell Kamrava, Tiffany M. Phillips, Jennifer M. Steers, Brad Stiehl

Affiliation: Department of Radiation Oncology,Cedars-Sinai Medical Center, Cedars-Sinai Medical Center

Abstract Preview: Purpose: Auto-contouring for HDR interstitial brachytherapy can be confounded by large deformation in anatomy and image quality. Here we evaluated the performance of an AI-based auto-contouring softwa...

An Investigational, or-Based Imaging Method for Reconstructing Catheters in Image-Guided HDR Brachytherapy

Authors: Margaret Cunningham Barker, Michael E. Campbell, Peyman Kabolizadeh, A. Nisar Syed, Randy Wei, Lisa M. Wilson-Turner

Affiliation: Memorial Radiation Oncology Medical Group, MemorialCare Todd Cancer Institute

Abstract Preview: Purpose:
Interstitial HDR treatment planning can be time-consuming, with substantial time spent waiting for the patient’s arrival and performing manual tasks, such as contouring ROIs and catheter r...

Brachify: An Open-Source 3D Modeling Solution for 3D Printable Cervical and Vaginal Cylindrical Templates

Authors: Michael Kudla, Stephanie Merkl

Affiliation: BC Cancer - Kelowna

Abstract Preview: Purpose: 3D modeling for 3D printed GYN high dose rate (HDR) brachytherapy templates can be a time-consuming, error-prone process. To simplify the creation these templates, a software application has ...

Dosimetric Evaluation of Clinical Venezia Hybrid Applicator Plans Using a TG-186 Model-Based Dose Calculation Algorithm

Authors: Davide Brivio, Ivan M. Buzurovic, Thomas C. Harris, Desmond A. O'Farrell

Affiliation: Department of Radiation Oncology, Brigham and Women’s Hospital, Dana-Farber Cancer Institute, Harvard Medical School, Brigham and Women's Hospital, Harvard Medial School, Dana-Farber Cancer Institute, Department of Radiation Oncology

Abstract Preview: Purpose: Cervical cancer can be treated with a brachytherapy boost following external beam radiotherapy. One applicator option is the Advanced Gynecological Applicator "Venezia" (Elekta) hybrid, consi...
