1. A wireless medical device-placing system comprising:
an ultrasound probe configured to emit ultrasound signals into a patient and receive echoed ultrasound signals from the patient by way of a piezoelectric sensor array;
a medical-device tip-location sensor (“TLS”) configured for placement on a chest of the patient; and
an alternative-reality headset configured to wirelessly communicate with the ultrasound probe and the TLS, the alternative-reality headset including:
a frame having electronic circuitry including memory and a processor configured to:
transform the echoed ultrasound signals to produce ultrasound-image segments corresponding to anatomical structures of the patient; and
transform TLS signals from the TLS into location information for a medical device within the patient when the TLS is placed on the chest of the patient; and
a display screen coupled to the frame through which a wearer of the alternative-reality headset can see an environment including the patient, the display screen configured to:
display a virtual medical device in accordance with the location information for the medical device within objects of virtual anatomy corresponding to the ultrasound-image segments;
display one or more graphical-control-element windows including output corresponding to one or more processes of the medical device-placing system; or
display both the virtual medical device within the objects of virtual anatomy and the one or more windows.
