Design of High-Resolution Photoacoustic Imaging System Based on LabVIEW Station
基于LabVIEW平台的高准确度光声成像系统设计

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.
