Vein Location and Feature Detection using Image Analysis

Abstract:

Transillumination is a non-invasive method of viewing body organs by using long wavelengths of light to penetrate the layers of the skin. This method can also be used in viewing the veins of a patient for venipuncture. This can reduce complications like hematoma and minor bruising that may arise during the process. Vein location using twelve red Light Emitting Diodes (LEDs) with a wavelength of 660 nm was performed and tested for transillumination. Microcontrollers, a Light-dependent resistor (LDR), and a camera were used for vein detection, capturing, and image processing. The real-time captured vein image can be visualized in a mobile phone. Participants with BMI of less than 25 and Fitzpatrick's skin types III and IV were the subject and focus of the study. The cephalic vein that is near the median cubital vein is the target for the detection because it is non-movable. Guidance of a registered medical practitioner in locating the proper region of the targeted vein was sought for verification. The tests yield a result of 70% accuracy for children, 90% for adolescents, 100% for adults, and 80% for the elderly.
