“…Focusing on this physical relationship, we devised a method of constructing a 3D moving image. This method uses the physical relationship to improve the accuracy of cardiac motion estimation by restraining it in accordance with the state transition, which is estimated from the heart sounds [2].…”

Biological sounds and electrocardiographic signals are important for understanding the physical and psychological state of a person. In this article, signal-processing and machine-learning technologies involving measuring biological sounds by using a wearable acoustic-sensor array, called a telestethoscope, as well as new measurement and analysis technology, i.e., tensor electrocardiogram using hitoe TM , are introduced. The possibility of early detection of diseases by using such personal heart modeling and its application to post-onset rehabilitation are also discussed.
