Method And Apparatus For Ultrasonic Analysis Of Brain Activity In Stroke Patients

A method comprising:

• transmitting ultrasound waves to a plurality of regions of a brain of a subject via one or more probes;
• receiving ultrasound echoes corresponding to the transmitted ultrasound waves;
• determining a parameter based on the ultrasound echoes for each region of the plurality of regions;
• determining a time course for each parameter;
• and
• comparing the time courses to one or more of, a known time course in normal brain tissue and a known time course in abnormal brain tissue to classify each region of the plurality of regions as comprising normal brain tissue or abnormal brain tissue.

A system comprising:

• one or more ultrasound transducers configured to transmit ultrasound waves to a plurality of regions of an object and receive backscattered ultrasound echoes corresponding to the transmitted ultrasound waves;
• a processor, coupled to the one or more ultrasound transducers, wherein the processor is configured to,
• transmit ultrasound waves to a plurality of regions of a brain of a subject via one or more probes;
• receive ultrasound echoes corresponding to the transmitted ultrasound waves;
• determine a parameter based on the ultrasound echoes for each region of the plurality of regions;
• determine a time course for each parameter;
• and
• compare the time courses for each region of the plurality of regions to determine a pulsatility measurement for each region of the plurality of regions.
