Automated Classification of Treatment Sites from Physician Consult Notes Using a Large Language Model

Authors: Klea Hoxha, Dylan P. O'Connell, Ricky R Savjani

Affiliation: Department of Radiation Oncology, University of California, Los Angeles, UCLA Radiation Oncology

Abstract Preview: Purpose: Ambiguities in physician simulation orders lead to workflow disruptions during CT simulation. Often, information that could provide
helpful context to simulation therapists and planners is...

Deep Learning-Based Fast CBCT Imaging with Orthogonal X-Ray Projections for Gynecological Cancer Radiotherapy

Authors: Beth Bradshaw Ghavidel, Chih-Wei Chang, Yuan Gao, Priyanka Kapoor, Shaoyan Pan, Junbo Peng, Richard L.J. Qiu, Jill Remick, Justin R. Roper, Zhen Tian, Xiaofeng Yang

Affiliation: Whinship Cancer Institute, Emory University, Emory University, University of Chicago, Department of Radiation Oncology and Winship Cancer Institute, Emory University

Abstract Preview: Purpose: Current cone-beam computed tomography (CBCT) typically requires no less than 200 degrees of angular projections, which prolongs scanning time and increases radiation exposure. To address thes...

Evaluation of Phosphorus-32 Source Uniformity Using Python Algorithm and Monte Carlo Simulation

Authors: Ana Laura Burin, Ilca Marli Moitinho Amaral Medeiros, Priscila Santos Rodrigues, Maria Elisa Chuery Martins Rostelato, Sabrina Spigaroli Sgrignoli, Ana Catarina Koka de Souza Silva, Carla Daruich Souza, Cristhian Ferreira Talacimon, Lara El Hajj Teodoro, Carlos Alberto Zeituni

Affiliation: IPEN - USP, IPEN - Instituto de Pesquisas EnergΓ©ticas e Nucleares

Abstract Preview: Purpose: The uniform distribution of phosphorus-32 (32P) in beta sources is essential to ensure the accuracy of radiotherapy treatments, such as those for paravertebral cancer. This study evaluated th...

Feasibility Study of Using HDR1000+ Well-Type Ionization Chambers for Solution Based 90y Measurements

Authors: Denis Bergeron, Larry A. DeWerd, Sean Jollota, Peyton Alexandra Lalain, Likhitha Polepalli

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

Abstract Preview: Purpose: 90Y is a challenging radionuclide to measure because it is a pure beta-emitter and is typically quantified using a radionuclide calibrator. These devices, such as the Capintec model used in t...

Intra-Organ Blood Vessel Mapping in Mice for Improved Pre-Clinical Radiation Dosimetry

Authors: Daylin Barroso, Chris Beekman, Wesley E. Bolch, Natalia Estefania Carrasco-Rojas, Robert Joseph Dawson, Walter Murfee, Harald Paganetti, Andrew Robert Sforza, Julia D. Withrow

Affiliation: Massachusetts General Hospital - Harvard Medical School, Massachusetts General Hospital, University of Florida

Abstract Preview: Purpose: To develop methods for quantifying the interaction of radiation with blood in the mouse whole body (MOBY) phantom for dosimetric applications. The most important of these are modeling the dis...

Ir-192 Percentage Depth Ionization of PLA and Ballistic Gelatin Compared to Water

Authors: ChangSeon Kim, Andrew Lukban, Mario Serrano-Sosa, Ching-Ling Teng, Nadia M. Vassell

Affiliation: Northwell, Mount Sinai Beth Israel

Abstract Preview: Purpose:
The flexible nature of ballistic gelatin and 3D printed material such as PLA lend themselves to phantom studies in brachytherapy. While these materials can allow for easy simulation of cat...
