HYBRID PHOTOACOUSTIC ULTRASOUND IMAGING SYSTEM FOR COLD-INDUCED VASOCONSTRICTION AND VASODILATION MONITORING

02 August 2023 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 […]

DEEP LEARNING ENABLED REAL-TIME PHOTOACOUSTIC TOMOGRAPHY SYSTEM VIA SINGLE DATA ACQUISITION CHANNEL

Authors: Hengrong Lana,b,c,1, Daohuai Jianga,b,c,1, Feng Gaoa, Fei Gaoa,* ABSTRACT Photoacoustic computed tomography (PACT) combines the optical contrast of optical imaging and the penetrability of sonography. In this work, we develop a novel PACT system to provide real-time imaging, which is achieved by a 120-elements ultrasound array only using a single data acquisition (DAQ) channel. […]
