摘要:Ultrasound cardiography(UCG) is costly device and is difficult to long-time monitoring of heart motion and its function.As a fresh idea,we found that slight vibration of the chest surface due to heartbeat allows visualizing the heart motion for assisting understands of heart function.The method based on a multi-channel vibration sensor and signal/image processing units.Vibration mode of the chest has three or four frequency bands,which allow visualizing region of the heart.Contour of heart wall with data of 1-50 Hz frequency and locations of valves with higher frequency can be visualized.The technique may allow to monitoring heart motion in an operation or after an operation,understanding irregular heartbeat,heart motion during sleeping and in state of mental tension without using an UCG device.
