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 optical contrast. However, […]

WHOLE-BODY HUMAN UTLRASOUND TOMOGRAPHY
Author(s): D. C. Garrett, J. Xu, D. Oh, Y. Aborahama, G. Ku, K. Maslov, W. W. Tseng, and L. V. Wang ABSTRACT We developed a system for whole-body human ultrasound tomography in reflection andtransmission modes. A custom 512-element ultrasound receiver array with a rotating single-element ultrasound transmitter are used to generate 2D isotropically resolved images […]
A COMBINED ULTRASOUND AND PHOTOACOUSTIC IMAGING PLATFORM FOR CLINICAL RESEARCH APPLICATIONS
Author(s): Weylan Thompson, Hans-Peter Brecht, Sergey A. Ermilov, Vassili Ivanov ABSTRACT We present the continued development of a clinical ultrasound (US) imaging device with a photoacoustic (PA) mode. The combined USPA imaging platform is designed around a compact US component capable of B-mode, M-mode, color Doppler, and pulsed wave Doppler US imaging modes with a 128-element US probe. […]
HYBRID PHOTOACOUSTIC ULTRASOUND IMAGING SYSTEM FOR COLD-INDUCED VASOCONSTRICTION AND VASODILATION MONITORING
Author(s): Ruochong Zhang, Xiuting Li, Ghayathri Balasundaram, Baocheng Li, Yi Qi, Anindita Santosa, Tze Chin Tan, Malini Olivo, Renzhe Bi ABSTRACT Lewis hunting reaction refers to the alternating cold-induced vasoconstriction and dilation in extremities, whose underlying mechanism is complex. While numerous studies reported this intriguing phenomenon by measuring cutaneous temperature fluctuation under cold exposure, few of them tracked peripheral vascular responses in real-time, […]
A 3D IMAGING SYSTEM INTEGRATING PHOTOACOUSTIC AND FLUORESCENCE ORTHOGONAL PROJECTIONS FOR ANATOMICAL, FUNCTIONAL, AND MOLECULAR ASSESSMENT OF RODENT MODELS
Authors: Hans P. Brecht, Vassili Ivanov, Diego S. Dumani, Stanislav Y. Emelianov, Mark A. Anastasio, Sergey A. Ermilov ABSTRACT We have developed a preclinical 3D imaging instrument integrating photoacoustic tomography and fluorescence (PAFT) addressing known deficiencies in sensitivity and spatial resolution of the individual imaging components. PAFT is designed for simultaneous acquisition of photoacoustic and fluorescence orthogonal projections at each […]
