Ultrasound detection of clots in the bloodstream

A method, comprising:

• capturing, using an ultrasound image sensor, an image sequence of a blood flow in a target region of a blood vessel;
• measuring, based on the image sequence,
• a central frequency corresponding to a first Doppler frequency shift of the blood flow viewed with the ultrasound image sensor in the target region of the blood vessel, and
• a second Doppler frequency shift corresponding to one or more objects suspended within the blood flow viewed with the ultrasound image sensor;
• determining, based on the central frequency and the second Doppler frequency shift, a differential in speed between the one or more objects suspended within the blood flow and the blood flow;
• and
• detecting, based at least on the differential in speed, that the one or more objects correspond to one or more anomalies present in the blood flow.

A system comprising:

• an ultrasound image sensor configured to capture an image sequence of a blood flow in a target region of a blood vessel;
• a non-transitory computer-readable medium having executable instructions stored thereon that, when executed by a processor, causes the system to perform operations comprising:
• measuring, based on the image sequence,
• a central frequency corresponding to a first Doppler frequency shift of the blood flow viewed with the ultrasound image sensor in the target region of the blood vessel, and
• a second Doppler frequency shift corresponding to one or more objects suspended within the blood flow viewed with the ultrasound image sensor;
• determining, based on the central frequency and the second Doppler frequency shift, a differential in speed between the one or more objects suspended within the blood flow and the blood flow;
• and
• detecting, based at least on the differential in speed, that the one or more objects correspond to one or more anomalies present in the blood flow.
