眼科光学相干断层扫描仪质量控制参数的测量方法分析

摘要

This paper describes the significance of quality control parameters of the optical coherence tomography (OCT) and makes a comparative analysis of the different methods of resolution measurement. Focusing on the ophthalmic OCT devices, their quality control indicators and meanings are described. Combined with the principle and application of OCT devices, this paper mainly researches on the resolution, which is one of the key quality control indicators. Then it gives a detailed comparison of the advantages and disadvantages of different methods of measurement.%　　本文主要介绍了光学相干断层扫描技术（OCT）质控参数的意义和分辨率测量方法的对比分析。着眼于眼科OCT设备，阐述了该类设备的质控指标及其含义；结合OCT设备的原理和应用情况，重点从技术层面和实现层面阐述了眼科OCT设备关键指标--分辨率的测量方法，同时还比较了不同测量方法的优劣。
