Augmented reality interface for assisting a user to operate an ultrasound device
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.

a camera;
a display; and
at least one processor configured to:
identify a pose of an ultrasound device based at least in part on a non-acoustic image captured with the camera of the mobile device, wherein the non-acoustic image depicts the ultrasound device and a subject being imaged by the ultrasound device;
generate an augmented reality interface, the augmented reality interface comprising an ultrasound image captured by the ultrasound device and overlaid onto the non-acoustic image; and
present the augmented reality interface on the display of the mobile device;
wherein:
the at least one processor is configured, when generating the augmented reality interface, to overlay the ultrasound image onto a portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image;

5. A method, comprising:
identifying a pose of an ultrasound device based at least in part on a non-acoustic image captured with a camera of a mobile device, wherein the non-acoustic image depicts the ultrasound device and a subject being imaged by the ultrasound device;
generating an augmented reality interface, the augmented reality interface comprising an ultrasound image captured by the ultrasound device and overlaid onto the non-acoustic image; and
presenting the augmented reality interface on a display of the mobile device;
wherein:
generating the augmented reality interface comprises overlaying the ultrasound image onto a portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image;
overlaying the ultrasound image onto the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image comprises positioning and orienting the ultrasound image such that the ultrasound image extends from the ultrasound device into the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image; and
positioning and orienting the ultrasound image such that the ultrasound image extends from the ultrasound device into the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image comprises positioning and orienting the ultrasound image such that the ultrasound image extends from an end of the ultrasound device in contact with the subject into the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image.
6. The method of claim 5 , wherein identifying the pose of the ultrasound device comprises identifying a distinctive characteristic of the ultrasound device as depicted by the non-acoustic image.
7. The method of claim 5 , wherein identifying the pose of the ultrasound device comprises using deep learning techniques.
8. The method of claim 5 , wherein the camera comprises a front-facing camera.
9. At least one non-transitory computer-readable storage medium storing processor-executable instructions that, when executed by at least one processor of a mobile device, cause the at least one processor to:
identify a pose of an ultrasound device based at least in part on a non-acoustic image captured with a camera of the mobile device, wherein the non-acoustic image depicts the ultrasound device and a subject being imaged by the ultrasound device;
generate an augmented reality interface, the augmented reality interface comprising an ultrasound image captured by the ultrasound device and overlaid onto the non-acoustic image; and
present the augmented reality interface on a display of the mobile device;
wherein:
the instructions, when executed by the at least one processor of the mobile device, cause the at least one processor to generate the augmented reality interface by overlaying the ultrasound image onto a portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image; and
overlaying the ultrasound image onto the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image comprises positioning and orienting the ultrasound image such that the ultrasound image extends from an end of the ultrasound device in contact with the subject into the portion of the subject that is being imaged by the ultrasound device as depicted by the non-acoustic image.
