Abstract
Systems and methods for stroke detection in accordance with embodiments of the invention are illustrated. One embodiment includes a system for detecting strokes, including a processor, a first ultrasound transmitter located on a patient's head in communication with the processor, a first ultrasound receiver located on the patient's head in communication with the processor, a memory in communication with the processor, including a stroke diagnostics application, where the stroke diagnostics application directs the processor to transmit a first ultrasound signal from the first ultrasound transmitter across a patient's brain, the brain comprising a first and second hemisphere, receive the first ultrasound signal using the 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 detect that a stroke has occurred based on the harmonic effects on the first received ultrasound signal.
