1. An ultrasound device, comprising:
a probe including a tube sized for insertion into a patient and an ultrasound transducer disposed at a distal end of the tube;
a camera mounted at the distal end of the tube in a fixed spatial relationship to the ultrasound transducer;
at least one electronic processor programmed to:
control the ultrasound transducer and the camera to acquire ultrasound images and camera images respectively while the ultrasound transducer is disposed in vivo inside the patient; and
construct a keyframe representative of an in vivo position of the ultrasound transducer, wherein the keyframe is a single image and wherein the keyframe includes at least: (i) ultrasound image features extracted from at least one of the ultrasound images acquired at the in vivo position of the ultrasound transducer, wherein the keyframe further includes, displayed within the single image, one or more settings of the ultrasound transducer at the acquisition time of the ultrasound image acquired at the in vivo position of the ultrasound transducer; and (ii) camera image features extracted from one of the camera images acquired at the in vivo position of the ultrasound transducer; and
a display configured to display the keyframe.
