摘要：
A method of detecting the vascular condition based on point fluctuation conduction characteristics of the heart and a device utilizing the same are disclosed in this patent. The method comprises: attaching flexible detection terminals firmly against the external skin adjacent to the heart or vascular walls； discretizing the detection area of the heart muscle or vascular walls into a plurality of preset detection points； through active emission of ultrasonic waves and continuous array reception of ultrasonic echoes carrying out multidimensional inversion of point fluctuations/point pulse waves using backend inversion； taking the multiple point fluctuations of the heart muscle as the multiple input signals of the vascular system and the multiple point pulse waves of a certain detection location of the blood vessel as the multiple output signals of the vascular system； identifying the vascular conduction characteristics by using digital signal processing methods； obtaining the conduction characteristics of a certain section of the blood vessel by decomposing the vascular conduction characteristics at different locations based on the cascade feature of the blood vessel； through feature extraction and feature comparison realizing the prediction and diagnosis of the vascular condition and the corresponding symptoms. The device comprises a plurality of flexible detection terminals with ultrasonic transceiving capability, a control module and a computing module, wherein the flexible detection terminal includes an ultrasonic transceiver probe array which is fixed on a flexible circuit board.
