中文摘要：

利用虚拟仪器开发软件LabVIEW设计了一套高准确度光声成像系统，整个系统在GPIB总线技术基础上，构架了由超声传感器、数字示波器、可调谐激光器、个人计算机等组成的硬件平台，并开发了配套的控制软件和高抗噪音图像重建算法．在活体脑结构成像中，实验鼠的左右脑、小脑、脑横裂和脑主动脉等脑结构成像清晰，大脑皮层的血管分布特征得到了完整的再现，系统成像分辨率可达200μm．该系统和方法可望发展为一种无损伤的生物组织结构与功能成像．

英文摘要：

A high-resolution photoacoutic imaging system based on virtual instrument development environment is presented. GPIB bus technology is employed in the overall system, whose platform is composed of an ultra-sound transducer,digital oscilloscope,tunable laser and a personal computer,and the corresponding software for controlling and high-antinoise reconstruction algorithm are explored on LabVIEW platform. In the structural imaging of the brain in vivo,the brain structures are imaged clearly, such as the left hemisphere, right hemisphere, cerebellum, fissure transversa cerebri and middle cerebral artery. Also the distributed character of vascular network in the superficial cortex is reproduced perfectly. The spatial resolution of the imaging system can reach 200 microns. The system and method can potentially be developed as a non-invasive biological structural and functional imaging technique.
