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.

Abstract: An ultrasonic device is provided and includes a base having an action portion, and a plurality of action members arranged on the action portion of the base for providing ultrasonic waves. The ultrasonic waves generated by the plurality of action members focus at different target positions so as to generate an acupuncture effect without invading into a human body during an acupuncture operation.
