Portable Ultrasound Device

A method for detecting strokes, comprising:

• transmitting a first ultrasound signal from a first ultrasound transmitter across a patient's brain, where the brain comprises:
• a first hemisphere;
• and
• a second hemisphere;
• and
• receiving the first ultrasound signal using a first ultrasound receiver, where the ultrasound signal is affected during transit by harmonics generated by microbubbles in the blood of the patient stimulated by the first ultrasound signal;
• and
• detecting that a stroke has occurred based on the harmonic effects on the first received ultrasound signal.

A system for detecting strokes comprising:

• a processor;
• an ultrasound transmitter element in communication with the processor;
• an ultrasound receiver element in communication with the processor;
• and
• a memory in communication with the processor, comprising a stroke diagnostics application, where the stroke diagnostics application directs the processor to:
• transmit an ultrasound signal across a patient's brain using the ultrasound transmitter element, where the blood in the patient's brain contains microbubbles;
• receive the ultrasound signal using the ultrasound receiver element;
• calculate the differences in the received ultrasound signal from the transmitted ultrasound signal based on microbubble harmonic resonance;
• and
• determine whether or not a stroke has occurred based on the microbubble harmonic resonance.
