【摘要】：尽管OCT早已在世界范围内获得临床诊断许可,但这项技术尚无任何国际标准。如何验证OCT的成像能力及有效性被认为是该技术标准化进程中的重要一环。本研究研制了一种可用于OCT三维成像分辨率测试的模拟眼。该模拟眼利用透明树脂材料仿真了人眼的重要光学元件:角膜与晶状体。采用3D打印技术在模拟眼眼底制作出了参照USAF1951靶板设计的三维分辨率测试图案。研究结果表明该模拟眼能够对OCT设备的三维成像分辨率性能进行初步评估,通过进一步改进,未来可用于注册检验或日常质控。
[Abstract]:Although OCT has already received worldwide permission for clinical diagnosis, However, there is no international standard for this technique. How to verify the imaging capability and effectiveness of OCT is considered to be an important part of the standardization process of this technology. A new model for OCT 3D imaging resolution testing has been developed in this study. The simulated eye uses transparent resin material to simulate the important optical components of the human eye: cornea and lens. The 3D printing technique is used to fabricate the 3D resolution test pattern with reference to the USAF1951 target plate in the simulated eye fundus. The results show that the simulated eye can be used to evaluate the resolution performance of 3D imaging of OCT devices. Through further improvement, the future can be used for registration inspection or routine quality control.
