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 […]
A 3D IMAGING SYSTEM INTEGRATING PHOTOACOUSTIC AND FLUORESCENCE ORTHOGONAL PROJECTIONS FOR ANATOMICAL, FUNCTIONAL, AND MOLECULAR ASSESSMENT OF RODENT MODELS
16 March 2018 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 […]
