Abstract

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

First claim

What is claimed is:

1. A system, comprising:
an ultrasound device configured to capture ultrasound images; and
a computing device communicatively coupled to the ultrasound device, the computing device being configured to:
receive medical information about a subject, wherein the medical information about the subject is selected from a group consisting of: a heart rate, a blood pressure, a body surface area, an age, a weight, a height, and a medication being taken by the subject;
identify, based on the medical information, a target anatomical view of the subject to be imaged by the ultrasound device;
obtain an ultrasound image containing the target anatomical view captured by the ultrasound device; and
generate a diagnosis of a medical condition of the subject using the ultrasound image containing the target anatomical view.

2. The system of claim 1 , wherein the ultrasound device comprises a plurality of ultrasonic transducers.

3. The system of claim 2 , wherein the plurality of ultrasonic transducers comprises an ultrasonic transducer selected from the group consisting of: a capacitive micromachined ultrasonic transducer (CMUT), a CMOS ultrasonic transducer (CUT), and a piezoelectric micromachined ultrasonic transducer (PMUT).

4. The system of claim 1 , wherein the computing device is a mobile smartphone or a tablet.

5. The system of claim 1 , wherein the computing device is configured to identify the target anatomical view at least in part by identifying an anatomical view of a heart of the subject as the target anatomical view responsive to the medical information about the subject indicating that the subject has experienced paroxysmal nocturnal dyspnea.

6. The system of claim 5 , wherein the computing device is configured to identify an ejection fraction of the subject using the ultrasound image containing the target anatomical view responsive to the medical information about the subject indicating that the subject has experienced paroxysmal nocturnal dyspnea.

7. The system of claim 1 , wherein the computing device is configured to generate the diagnosis of the medical condition of the subject at least in part by identifying at least one medical parameter of the subject using the ultrasound image containing the target anatomical view.

8. At least one non-transitory computer-readable storage medium storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to:
receive medical information about a subject, wherein the medical information about the subject is selected from a group consisting of: a heart rate, a blood pressure, a body surface area, an age, a weight, a height, and a medication being taken by the subject;
identify, based on the medical information, a target anatomical view of the subject to be imaged by an ultrasound device;
obtain an ultrasound image containing the target anatomical view captured by the ultrasound device; and
generate a diagnosis of a medical condition of the subject using the ultrasound image containing the target anatomical view.

9. A method, comprising:
receiving, by at least one processor, medical information about a subject, wherein the medical information about the subject is selected from a group consisting of: a heart rate, a blood pressure, a body surface area, an age, a weight, a height, and a medication being taken by the subject;
identifying, by the at least one processor, based on the medical information, a target anatomical view of the subject to be imaged by an ultrasound device;
obtaining, by the at least one processor, an ultrasound image containing the target anatomical view captured by the ultrasound device; and
generating, by the at least one processor, a diagnosis of a medical condition of the subject using the ultrasound image containing the target anatomical view.
