4D IN VIVO DOSIMETRY FOR A FLASH ELECTRON BEAM USING RADIATION-INDUCED ACOUSTIC IMAGING
Authors: Kristina Bjegovic, Leshan Sun, Prabodh Pandey, Veljko Grilj, Paola Ballesteros-Zebadua, Ryan Paisley, Gilberto Gonzalez, Siqi Wang, Marie Catherine Vozenin, Charles L Limoli and Shawn (Liangzhong) Xiang ABSTRACT Objective. The primary goal of this research is to demonstrate the feasibility of radiation-induced acoustic imaging (RAI) as a volumetric dosimetry tool for ultra-high dose rate FLASH […]
TOWARD REAL-TIME, VOLUMETRIC DOSIMETRY FOR FLASH-CAPABLE CLINICAL SYNCHROCYCLOTRONS USING PROTOACOUSTIC IMAGING
Authors: Siqi Wang, Gilberto Gonzalez, Daniel Rocky Owen, Leshan Sun, Yan Liu, Townsend Zwart, Yong Chen, Liangzhong Xiang ABSTRACT BackgroundRadiation delivery with ultra-high dose rate (FLASH) radiotherapy (RT) holds promise for improving treatment outcomes and reducing side effects but poses challenges in radiation delivery accuracy due to its ultra-high dose rates. This necessitates the development […]
REAL-TIME TRACKING OF THE BRAGG PEAK DURING PROTON THERAPY VIA 3D PROTOACOUSTIC IMAGING IN A CLINICAL SCENARIO
Authors: Siqi Wang, Gilberto Gonzalez, Leshan Sun, Yifei Xu, Prabodh Pandey, Yong Chen & Shawn (Liangzhong) Xiang ABSTRACT Proton radiotherapy favored over X-ray photon therapy due to its reduced radiation exposure to surrounding healthy tissues, is highly dependent on the accurate positioning of the Bragg peak. Existing methods like PET and prompt gamma imaging to […]

Discrete Wavelet Transformation for the Sensitive Detection of Ultrashort Radiation Pulse with Radiation-Induced Acoustics
Authors: Rick Van Bergen, Leshan Sun, Prabodh Kumar Pandey, Siqi Wang, Kristina Bjegovic, Gilberto Gonzalez, Yong Chen, Richard Lopata, Liangzhong Xiang ABSTRACT Radiation-induced acoustics (RIA) shows promise in advancing radiological imaging and radiotherapy dosimetry methods. However, RIA signals often require extensive averaging to achieve reasonable signal-to-noise ratios, which increases patient radiation exposure and limits real-time […]

MONODISPERSE SUB-100 NM AU NANOSHELLS FOR LOW-FLUENCE DEEP-TISSUE PHOTOACOUSTIC IMAGING
August 4, 2023 Author(s): Luis D. B. Manuel, Vinion Devpaul Vincely, Carolyn Bayer, and Kevin M. McPeak ABSTRACT Nanoparticles with high absorption cross sections will advance therapeutic and bioimaging nanomedicine technologies. While Au nanoshells have shown great promise in nanomedicine, state-of-the-art synthesis methods result in scattering-dominant particles, mitigating their efficacy in absorption-based techniques that leverage […]
NON-INVASIVE 3D PHOTOACOUSTIC TOMOGRAPHY OF ANGIOGRAPHIC ANATOMY AND HEMODYNAMICS OF FATTY LIVERS IN RATS
17 November 2022 Author(s): Xin Tong, Li Lin, Peng Hu, Rui Cao, Yang Zhang, Joshua Olick-Gibson,and Lihong V. Wang ABSTRACT Non-alcoholic fatty liver disease is the most common liver disorder worldwide, which strongly correlates to obesity, diabetes, and metabolic syndromes. Complementary to mainstream liver diagnostic modalities, photoacoustic tomography (PAT) can provide high-speed images with functional […]
