Abstract
A method for detecting vascular obstruction and a system using the same are provided. The method includes steps of: detecting a blood vessel through a probe to generate a reference signal before the blood vessel is obstructed, wherein the probe is configured to transmit or receive ultrasonic waves; detecting the blood vessel through the probe to generate a detection signal; performing Fourier transformation on the reference signal to generate a reference power spectrum, and performing Fourier transformation on the detection signal to generate a detection power spectrum; transforming the reference power spectrum into a reference time-frequency spectrogram, and transforming the detection power spectrum into a detection time-frequency spectrogram; judging a similarity between the reference time-frequency spectrogram and the detection time-frequency spectrogram, and judging whether the blood vessel is obstructed or not according to the similarity.
