Principle | Using the principle that hemoglobin in blood absorbs infrared light more strongly than other tissues, first, near-infrared light of a specific wavelength is projected to the skin surface, and the infrared image of the skin is collected by photosensitive components. Figure, and then the image is clearly displayed on the skin surface by micro-projection technology. |
Features | Brightness, size can be adjusted, modes can be selected, and photos can be stored. |
Precautions | Angiography can only identify venous vessels and cannot effectively evaluate arterial vessels. |
