In vivo mice brain microcirculation monitoring based on contrast... In this paper, we proposed a contrast-enhanced homemade spectral domain optical coherence tomography (SD-OCT) method for monitoring of brain microcirculation. We used the polyethylene glycol (PEG)-ylated gold nanorods (GNRs) as a contrast-enhanced agent, ...
In vivo monitoring of microneedle-based transdermal drug deliver... ... of MNs in vivo to estimate the efficiency of insulin delivery is difficult. We monitored the dissolution of MNs to obtain structural imaging of MNs' changes by using optical coherence tomography (OCT). We also observed the effect of MNs on microvascul
一种分布式EIT系统主控板的嵌入式程序设计本文设计实现了一种分布式生物电阻抗层析成像（Electrical Impedance Tomography， EIT）数据采集系统主控板的嵌入式控制软件。主要功能包括：产生激励信号、产生前端测量同步、与前端测量模块通信、与上位机通信。该软件能判断当前测量状态，实现多通道同步测量，具有很高的可靠性和灵活性。每个前端板通过主控板的广播信息获得系统当前工作的电极数目和单次测量点数等信息，进而修改测量配置参数，以与不同电极数目的EIT系统相匹配，便于进行不同应用领域的实验研究。
电阻抗成像系统中电压控制电流源的设计在医用电阻抗层析成像（Electrical Impedance Tomography）系统中电压控制电流源的性能十分重要，大部分报道的电压控电流源电路在低频时有较高的输出阻抗但是在高频时性能大幅减弱。通过分析生物阻抗测量系统对电压控制电流源的需求，同时回顾一些已有的电压控制电流源电路，包括双运放负反馈电路、跨导运算放大器、AD844，设计了一种基于AD8610的电压控制电流源。并通过电路实验验证了此电压控制电流源的性能，同时提出了改进方案。该电压电流源不仅频率和幅值可控、精度高，而且有较高的输出阻抗。
A comparative study on water and dry coupling in photoacoustic t... We present a systematical study on comparison between water and dry coupling in photoacoustic tomography of the human finger joints. Compared to the direct water immersion of the finger for water coupling, the dry coupling is realized through a ...
PERFORMANCE OF BLIND DECONVOLUTION IN OPTOACOUSTIC TOMOGRAPHY In this paper, we consider the use of blind deconvolution for optoacoustic (photoacoustic) imaging and investigate the performance of the method as means for increasing the resolution of the reconstructed image beyond the physical restrictions of the ...
IN VIVO VALIDATION OF DUAL-MODALITY SYSTEM FOR SIMULTANEOUS POSI... We report on tests of combined positron emission tomography (PET) and fluorescence molecular tomography (FMT) imaging system for in vivo investigation on small animals. A nude mouse was inoculated with MD-MB-231 breast cancer cells which expressed red ...
LIVE IMAGING OF EARLY DEVELOPMENTAL PROCESSES IN MAMMALIAN EMBRY... ... tissue layers with high spatial and temporal resolution. In this paper we evaluate the capability of Optical Coherence Tomography (OCT) technique for structural 3D embryonic imaging in mouse embryos at different stages of the developmental process ranging ...
Monte Carlo light transport-based blood vessel quantification us... Photoacoustic tomography is a noninvasive and nonionized biomedical imaging modality but it cannot reveal the inner structure and ... explores the combination of linear array transducer-based photoacoustic tomography and MC light transport in the blood vessel ...
Feasibility study of phase-sensitive imaging based on multiple r... Multiple reference optical coherence tomography (MR-OCT) is a recently developed, low-cost and compact time-domain OCT solution for primary care and consumer level applications. A combination of a voice coil actuator and a partial mirror (PM) extends the ...
