Abstract

The invention discloses a device and a method for detecting a blood vessel. The device comprises a visible light source, an optical fiber coupler, a lighting optical fiber, an imaging receiving channel, an infrared beam splitter, a far infrared lens zoom system, a far infrared detector, a visible light lens zoom system, a visible light image sensor and an image processing system. According to the characteristic and the blood vessel blood flow heat transfer property that different heat radiation is generated by metabolic activity of hot body cells, tissues or organs in different states, infrared thermal imaging technology is integrated with visible light imaging technology, a high-quality and high-contrast blood vessel image is acquired, analysis of related blood flow parameters such as blood vessel blood flow speed and blood perfusion can be assisted, and early disease prediction and health assessment are performed according to temperature characteristics of human tissues under different pathologies.

Description

technical field

[0001] The invention relates to the technical field of biological optical imaging, in particular to a device and method for detecting blood vessels. Background technique

[0002] In the human body, blood vessels are the pipelines that transport blood, and can be divided into arteries, veins and microvessels according to the direction of transport. Arteries bring blood from the heart to body tissues, veins bring blood back to the heart from the tissues, and microvessels connect arteries and veins, which are the main places for material exchange between blood and tissues, and are widely distributed among tissues and cells throughout the body. Capillaries are also called microcirculation.

[0003] Under normal circumstances, the blood flow of microvessels adapts to the metabolic level of human tissues and organs, so as to ensure the blood perfusion flow of various tissues and organs and regulate the amount of blood returned to the heart, so that the physiologic...
