A Retrospective Analysis of Automatic Exposure Control (AEC) Tracking Failure Rates in Radiographic Systems

Authors: Benjamin W. Maloney, Ashley E. Rubinstein, Colin Schaeffer, Justin Yu

Affiliation: Henry Ford Health

Abstract Preview: Purpose: Radiography AEC systems ensure correctly exposed images for varied kVp and patient thicknesses. The specific kVp and PMMA thicknesses selected for testing AEC tracking may affect passing rate...

Absorption and Material Property Characteristics of 3D-Printing Filaments Based on Monte-Carlo Simulations and Spectral Imaging

Authors: Izabella L. Barreto, Benjamin Taylor Heggie, Stephanie M. Leon

Affiliation: University of Florida College of Medicine, University of Florida

Abstract Preview: Purpose: 3D printing has the potential for producing materials useful for the imaging field. This work aims to identify absorption (attenuation coefficient) and material properties (effective atomic n...

Initial Phantom Studies Towards Implementation of Sequential Dual Energy CBCT on an Adaptive Radiotherapy Linac Platform

Authors: James M. Balter, Alexander Moncion, Ikechi S Ozoemelam

Affiliation: University of Michigan

Abstract Preview: Purpose: Sequential dual-energy cone beam computed tomography (DE-CBCT) integrated with an online adaptive platform could potentially improve soft tissue visualization for more accurate anatomical del...

Isocenter Stability after Commissioning of Biology-Guided Radiotherapy (BgRT)

Authors: Emily Hansen, Alois M. Ndlovu, Niara Rowe, Roland Teboh

Affiliation: Hackensack University Medical Center

Abstract Preview: Purpose: The accuracy of SCINTIX biology-guided radiotherapy (BgRT) on the RefleXion X1 is dependent on the correct alignment of the isocenter between all subsystems, including setup lasers, kV imagin...

Monte Carlo Modeling of an Experimental X-Ray Fluorescence Computed Tomography (XFCT) System with a Pixelated CdTe Detector

Authors: Sang Hyun Cho, Sandun Y. Jayarathna, Neerajan Nepal

Affiliation: The University of Texas MD Anderson Cancer Center

Abstract Preview: Purpose: To develop/validate a Monte Carlo (MC) model of an experimental benchtop x-ray fluorescence computed tomography (XFCT) system with a pixelated CdTe detector that can be used for MC simulation...

Study of PSMA-PET/MR Biomarkers for Prostate Stereotactic Radiotherapy Planning

Authors: Guillermo Daniel Alvarez, Daniel Fino, Rocio Luz Gilli, Dorian Alexander Romero

Affiliation: School Foundation of Nuclear Medicine, INTECNUS Foundation, Nuclear Medicine and Radiotherapy Center of Southern Patagonia

Abstract Preview: Purpose: To evaluate the anatomical, functional, and molecular information from PET/MR images with F18-PSMA to identify intraprostatic lesions and delineate a boost in stereotactic body radiotherapy (...
