Subcutanous Blood Vessels Imaging System

摘要

A real time imaging system is described which displays subcutaneous veins whereby facilitating diagnosis, inspection and easy intravenous access for administration of drugs. The imaging system comprises an infrared source (1), a pinhole focusing unit (7), an infrared Focal Plane Array (8), and a display unit (10). The infrared source (1) emits infrared light which penetrates and is subsequently scattered differently at different layers and depths of the anatomical structure (11) while substantially being absorbed by the blood vessels. Reflected light (4) from the anatomical structure (11) contains the imaging information of the subcutaneous blood vessels of the anatomical structure (11) which is then focused by said pinhole focusing unit (7) upon said infrared Focal Plane Array (8). The image captured by said infrared Focal Plane Array is then displayed on the display unit (10).
