Authors: Vassili Ivanov, Hans Peter Brecht, Sergey A. Ermilov ABSTRACT Large number of simultaneously acquired spatially distinct pressure signals is required to improve quality of real-time photoacoustic and x-ray acoustic biomedical images [1]. In the past this approach was limited by availability of commercial multi-channel analog-to-digital converter (ADC) systems and ability to operate multiple ADC […]

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 […]
