The purpose of this study was to establish the objective evaluation methods for spatial resolution of OCT (optical coherence tomography) for dental use by the physical analysis using MTF. The spatial resolution in which MTF in the depth directions decreases to 50% and 10% was 6 cycles/mm and 11-12 cycles/mm, respectively. We consider that these results will provide useful information in order to evaluate the clinical application of OCT in dentistry.

本研究的目的是通过MTF的物理分析，建立牙科光学相干断层扫描空间分辨率的客观评价方法。深度方向MTF减小至50%和10%的空间分辨率分别为6 cycles/mm和11 ~ 12 cycles/mm。我们认为这些结果将为评估OCT在牙科的临床应用提供有用的信息。
