Abstract

Blood vessel imaging is essential for diagnosing and treating ear-related diseases like tinnitus caused by altered blood flow. However, existing methods using cadaver samples have limitations due to vessel collapse or loss. This study utilizes optical coherence tomography angiography (OCTA), a non-invasive, label-free imaging of ear blood vessels. Customized imaging tips and a complex differential variance algorithm enhance OCTA image quality. Vascular distribution in 10 volunteers (5 male, 5 female) is successfully imaged. Internal factors, such as skin condition and body fat percentage, affect image quality by influencing light penetration, signal-to-noise ratio, and system robustness. Quantitative values for 20 parameters are obtained, enabling comparative analysis of blood vessel images. The findings demonstrate OCTA's potential in diagnosing and treating ear-related diseases and provide insights into blood vessel dynamics.
