GPU-Accelerated 3D Volumetric X-Ray-Induced Acoustic Computed Tomography

Author(s): Donghyun Lee, Eun-Yeong Park, Seongwook Choi, Hyeongsub Kim, Jung-joon Min, Changho Lee, and Chulhong Kim ABSTRACT X-ray acoustic imaging is a hybrid biomedical imaging technique that can acoustically monitor X-ray absorption distribution in biological tissues through the X-ray induced acoustic effect. In this study, we developed a 3D volumetric X-ray-induced acoustic computed tomography (XACT) […]

X-Ray Acoustics

What is X-Ray Acoustics? X-Ray Acoustics is the conversion of pulsed X-rays into sound waves. The interaction of X-rays and tissue is weaker than that of optical light which allows for deep penetration. However, the same weak interaction is greatly reducing contrast. The long pulse duration of X-ray sources limits the spatial resolution of X-ray […]

IN SITU X-RAY-INDUCED ACOUSTIC COMPUTED TOMOGRAPHY WITH A CONTRAST AGENT: A PROOF OF CONCEPT

Authors: Seongwook Choi,1; Sinyoung Park,1; Ayoung Pyo,2; Dong-Yeon Kim,3 ; Jung-Joon Min,4 ; Changho Lee,4,5,6; Chulhong Kim,1,7 ABSTRACT X-ray-induced acoustic computed tomography (XACT) has shown great potential as a hybrid imaging modality for real-time non-invasive x-ray dosimetry and low-dose three- dimensional (3D) imaging. While promising, one drawback of the XACT system is the underlying low signal-to-noise ratio […]
