PROCÉDÉ DE DÉTECTION D'UNE AFFECTION VASCULAIRE SUR LA BASE D'UNE CARACTÉRISTIQUE DE FLUCTUATION DE CONDUCTANCE EN UN POINT CARDIAQUE ET DISPOSITIF ASSOCIÉ
A method of detecting a vascular condition based on a heart spot fluctuation conductance characteristic and a device utilizing the same. The method comprises: attaching a flexible detection terminal firmly against external skin adjacent to a heart muscle or a vascular wall, dividing detection areas at the heart muscle or the vascular wall into a plurality of preconfigured detection spots; actively transmitting an ultrasound wave and receiving, by an array, a reflected ultrasound wave, so as to perform, by adopting back-end inversion, a multi-dimensional detection on a spot fluctuation or a spot pulse; identifying a vascular conductance characteristic by taking a plurality of spot fluctuations of the heart muscle and a plurality of spot pulses at a certain vascular detection area to be multiple input signals and multiple output signals, and performing digital signal processing; performing characteristic decomposition to obtain a vascular conductance characteristic, and performing, after characteristic extraction, a comparison with respect to the characteristic to implement symptom prediction and diagnosis of a vascular condition. The device comprises a plurality of flexible detection terminals having transmission and receiving capabilities, a control module and a computation module. An ultrasonic probe having integrated transmission and receiving functionalities is arranged at the flexible detection terminal and fixed on a flexible circuit board.L'invention concerne un procédé de détection d'une affection vasculaire sur la base d'une caractéristique de conductance de fluctuation en un point cardiaque et un dispositif associé.
