High-Order Near-Infrared Image Technology within Smart Medical Care Systems

The human eye can feel the color change of the surrounding things. It is because when the sun shines on an object, although some of the light is absorbed, some of the light is reflected to the human eye through the surface of the object. So we can feel different colors. The part that our eyes can see is called visible light and its wavelength range is about 0.4-0.7 micrometers (μm). The high-order near-infrared wavelength range is approximately (0.76 to 0.90 μm), and imaging technology is used in smart medical care systems. It is used in hemodialysis arteriovenous fistulas, which is a vascular anastomosis operation. In addition catheter ultrasound can be used for minimally invasive cardiac catheterization. It provides a smart cloud-based minimally invasive medical mechanism and drives the research and development of related industries. Arteriovenous fistula types: There are several types of vascular access, the most common being autologous fistulas and artificial blood vessels.
