Radio-Acoustic Monitoring of Electron Flash Therapy In Vivo

Authors: Kristina Bjegovic, Luke Connell, Emil Schueler, Leshan Sun, Lucy Whitmore, Liangzhong Xiang

Affiliation: University of California, Irvine, MD Anderson, Department of Radiation Physics, The University of Texas MD Anderson Cancer Center

Abstract Preview: Purpose: The use of FLASH-RT in the clinic would greatly reduce off-target radiation toxicity in normal tissues. However, due to the hypo-fractionated delivery of prescribed doses at FLASH dose rates,...

Shape-Optimized Radiation-Induced Acoustic Computed Tomography for In Vivo online Monitoring of Radiation Therapy

Authors: Yong Chen, Gilberto Gonzalez, Omprakash Gottam, Liangzhong Xiang

Affiliation: University of California, Irvine, Koneru Lakshmaiah Education Foundation, University of Texas at San Antonio., University of Oklahoma Health Science Center

Abstract Preview: Purpose: Clinics currently lack techniques for real-time, in vivo monitoring of radiation therapy (RT), which is desirable for precise treatment. Radiation-induced acoustic computed tomography (RACT) ...
