We report a method to image facial cutaneous microvascular perfusion using wide-field imaging photoplethysmography (iPPG) and handheld swept-source optical coherence tomography (OCT). The iPPG system employs a 16-bit-depth camera to provide a 2D wide-field blood pulsation map that is then used as a positioning guidance for OCT imaging of cutaneous microvasculature. We show the results from iPPG and OCT to demonstrate the ability of guided imaging of cutaneous microvasculature, which is potentially useful for the assessment of skin conditions in dermatology and cosmetology.
我们报告了一种使用宽场成像光电容积描记法（iPPG）和手持式扫频源光学相干断层扫描（OCT）对面部皮肤微血管灌注进行成像的方法。iPPG系统采用16位深度相机来提供二维宽场血液搏动图，该图随后用作皮肤微血管OCT成像的定位指导。我们展示了iPPG和OCT的结果，以证明皮肤微血管引导成像的能力，这对于皮肤科和美容学中皮肤状况的评估可能是有用的。
