Contactless Measurement of Motion of Human Cardiovascular Using Array Antennas Spatial Signal Processing

循环系统疾病，如动脉硬化和心肌梗塞是一种严重的疾病，占日本人疾病死亡的第二大原因。 对于心血管疾病的预防和早期诊断，患者的负担小，因此，需要比以前更高准确性的诊断方法。 为了实现对研究对象心脏、动脉等心血管组织运动的测量，提取诊断信息，研制了“微波阵列天线空间信号处理实验装置”。 使用该实验装置进行非接触式测量，而不损害人体和人体心血管周围器官的运动。 因此，我们成功地捕获了心跳和呼吸引起的信号波动的单独运动。

Circulatory diseases, such as arteriosclerosis and myocardial infarction is a serious disease, which account for the second leading cause of death by disease of Japanese. For the prevention and diagnosis early diagnosis of cardiovascular disease, the burden of patients is small and therefore, diagnostic method with high accuracy is required than before. The attempt has been aimed at the realization, and to measure the motion of cardiovascular tissues such as heart and arteries in the present study object, and extracts the information for diagnosis.For the purposes of this study challenge, "Experimental equipment of spatial signal processing for micro-wave array antenna" was produced. Contactless measurements were performed without damaging the body and motion of organs of human cardiovascular surrounding using this experimental equipment. As a result, we succeeded in capturing separate motion by the heart beat and signal fluctuations due to respiration.
