1. A system for detecting abnormal blood flow in brains, comprising:
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, comprising a diagnostics application, where the diagnostics application directs the processor to:
transmit a first ultrasound signal from the first ultrasound transmitter across a patient's brain, where the first ultrasound signal comprises a plurality of ultrasound pulses;
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;
identify a portion of the received first ultrasound signal indicative of abnormal blood flow based on harmonic effects in the received signal;
time-box the first received ultrasound signal such that at least a portion of the patient's brain is overlaid with the first received ultrasound signal; and
detect that an abnormal blood flow event has occurred in a region of the brain within the portion of the patient's brain based on the location of the identified portion of the first received ultrasound signal.
