摘要：
A method for measuring sound from vortices in the carotid artery comprising: a first and second quality control provisions, wherein the quality control compares detected sounds to pre-determined sounds, and upon confirmation of the quality control procedures, detecting sounds generated by the heart and sounds from vortices in the carotid artery for at least 30 seconds. A method for determining stenosis of the carotid artery in a human patient consisting of a first step of placing a sensing device comprising an array and three sensing elements onto the patient, wherein a first sensing element is placed near the heart and the two remaining sensing elements are placed adjacent to the carotid arteries； the sensing elements then measure sounds from each of the three sensing elements, resulting in sound from three channels. The sound is measured in analog and modified to digital format and then each of the three channels are analyzed before a power spectral density analysis is performed. The power spectral density graph reveals peaks that are not due to noise, that are then analyzed to provide for a calculation of percent stenosis or complete occlusion of the carotid artery.Un método para medir el sonido de los vórtices en la arteria carótida que comprende: una primera y segunda disposiciones de control de calidad, en donde el control de calidad compara los sonidos detectados con los sonidos predeterminados y, al confirmar los procedimientos de control de calidad, detecta los sonidos generados por el corazón y sonidos de vórtices en la arteria carótida durante al menos 30 segundos.
