No, they cannot.
Ultrasound is listed as a vision upgrade for cameras.
However, it is not in the list of eyeware options for cybereyes. Only eyeware accessories can be installed in eyeware capacity. Only earware accessories can go in earware capacity.
They're listed as bodyware. So they use up capacity in a cyberlimb, or are implanted seperately.
(they still don't work for magic spell targetting as they substitute processed data into a vision overlay, they aren't vision themselves).
