摘要： 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.

摘要： Systems and methods for measuring flow velocities, including ultrasound systems, are provided. A Doppler angle between a direction of ultrasound signals and an axis of a flow may be estimated to improve the accuracy of the flow velocity estimation that is based on Doppler effects. A sensor may be mounted on or in an ultrasound probe to obtain a reference orientation of the ultrasound probe and an orientation of the ultrasound probe relative to the reference orientation when the ultrasound probe is moved to other positions. The Doppler angle may be estimated based on the orientation of the ultrasound probe.

摘要： An ultrasound imaging system includes a beam receiving circuit and a back-end circuit. The beam receiving circuit receives a plurality of digitized echo signals. The back-end circuit is coupled to the beam receiving circuit for outputting a plurality of compressed delay timing parameters corresponding to a plurality of channels to the beam receiving circuit. The beam receiving circuit decompresses the compressed delay timing parameters into a plurality of delay timing parameters, and processes the digitized echo signals into an ultrasound beamforming value according to the delay timing parameters corresponding to the channels. The back-end circuit synthesizes an ultrasound image according to the ultrasound beamforming value outputted from the beam receiving circuit.
