Deep Vein Thrombosis (DVT) is caused by blood clots in a deep vein. Doppler ultrasound image is often applied to detecting DVT and evaluating the treatment efficiency of DVT, allowing physicians to observe visible clots and to measure flow velocity of blood flowing in veins. However, during the examinations using Doppler ultrasound, the scatterers properties of clots (e.g., the arrangements and concentration of red blood cells) are very difficult to be reflected so that the diagnostic information is limited.
This study proposes using ultrasound Nakagami imaging to visualize the change in the scatterers properties of clot during clot dissolution. We used a 35MHz single-element transducer and a clinical 7.5MHz array transducer to measure clot samples during their dissolution. By the clot daily information and Nakagami parameter analyzed the specification on the ultrasound signals. The result reveals the Nakagami image is suitable for the blood clot quantitative information.
