1. A method comprising:
- applying, to at least one transducer, an ultrasound signal to cause the at least one transduce to transmit ultrasound to a location on a patient'"'"'s body;
administering acoustic amplifiers intravenously to the patient; and
monitoring a feedback acoustic response signal from the at least one transducer to receive data indicative of an acoustic response of the acoustic amplifiers triggered by the ultrasound,wherein, an acoustic response signature of the feedback acoustic response signal enables a diagnosis based at least in part on a relationship between the acoustic response signature and a baseline acoustic response signature.

Abstract
A method of diagnosing the occurrence or non-occurrence of a blood vessel blockage or hemorrhage comprises non-invasively applying ultrasound to a location on a patient'"'"'s body, where the ultrasound is applied in an alternating and pulsed fashion, administering acoustic amplifiers to the patient, monitoring a feedback acoustic response signal of the acoustic amplifiers triggered by the ultrasound, and determining a diagnosis based at least in part on a relationship between an acoustic response signature of the acoustic response signal and a baseline acoustic response signature.

9. A system, comprising:
-
two ultrasound transducer elements configured to provide ultrasound to a patient; a power and control module (PCM) device communicatively coupled to the two ultrasound transducer elements and configured to; control the application of the ultrasound to trigger an acoustic response from acoustic amplifiers infused into the patient; and monitor a feedback acoustic response signal from the two ultrasound transducers to receive data indicative of the acoustic response, wherein an acoustic response signature of the feedback acoustic response signal enables a diagnosis based at least in part on a relationship between the acoustic response signature and a baseline acoustic response signature. - View Dependent Claims (10, 11, 12, 13, 14)
