In recent years various diseases exist in the world. In this study, we target at Pulmonary Hypertension that is known as the intractable disease. The treatment at appropriate timing is particularly essential to the intractable disease. At present, blood flow velocity and blood pressure are measured using an invasive catheter and the phase difference between them is measured to calculate pulmonary artery occlusion degree. However, in recent years noninvasive diagnosis is considered desirable. Therefore, in this research, we will conduct a study to propose a noninvasive diagnostic method using ultrasound diagnostic imaging equipment. Measure blood flow velocity and blood vessel outer diameter using ultrasonic waves. It was confirmed that the phase angle differs according to the degree of vascular occlusion by comparison of simulation results, experimental results using silicone tubes, and clinical data.
