A Dosimeter Independent Method for Measuring Dose from Contrast Enhanced Mammography Exposure.

Authors: Mitya M. Barreto, Nichole A. Harris

Affiliation: Department of Radiology, University Hospitals Cleveland Medical Center

Abstract Preview: Purpose: To evaluate dosimeter dependence of measured AGD, and to develop a dosimeter independent method for evaluating the AGD, for CEDM exposures.
Methods: Three solid-state dosimeters (Raysafe-X...

Calorimetric Measurement of Absorbed Dose By a Flash Beamline

Authors: Luke Connell, Stephen F. Kry, Malcolm R. McEwen, Bryan R. Muir, James Renaud, Emil Schueler, Hayden Scott, Paige A. Taylor

Affiliation: National Research Council, The University of Texas MD Anderson Cancer Center, UT MD Anderson Cancer Center, Department of Radiation Physics, The University of Texas MD Anderson Cancer Center

Abstract Preview: Purpose: To demonstrate the capability of a robust calorimeter to accurately determine the absorbed dose delivered by an electron FLASH beamline.

Feasibility of Commercial Independent-Dose-Calculation for Pencil-Beam-Scanning Proton Therapy

Authors: Wen C. Hsi, Kayla Schneider

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

Abstract Preview: Purpose:
Measurement-based patient-specific quality-assurance (PSQA) conducted with a 2D dosimeter to verify delivered dose of each field over 3 measurement-depths is time-consuming with limited se...

Neutron Dose Measurements with Multiple Dosimetry Techniques for Fetal Dose Estimation

Authors: Ahmet S. Ayan, Estelle Batin, Austin M. Faught, Peter E. Klages, Eunsin Lee, Collin Nappi, Mina Okello, Meghana Ramani, Zachary X. Richards, Parisa Sadeghi

Affiliation: Department of Radiation Oncology, The Ohio State University Wexner Medical Center, The Ohio State University Wexner Medical Center, Ohio State University, The Ohio State University

Abstract Preview: Purpose: Neutron doses are not modelled in proton treatment planning systems, so measurements were taken with two independent dosimeter types to quantify representative neutron fetal doses in pencil b...

Prior-Informed Neural Super-Resolution Dosimetry for Radiotherapy QA from Sparse Dosimeter Arrays

Authors: Muhammad Ramish Ashraf, Clinton Gibson, Gregory Szalkowski, Lei Wang, Siqi Wang, Lei Xing

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

Abstract Preview: Purpose: To develop a neural network-based super-resolution framework for enhancing the resolution of sparse dosimetry measurements in patient-specific radiotherapy QA. Sparse detector arrays, such as...
