1. An ultrasound system comprising:
an ultrasound scanner configured to transmit ultrasound at a patient anatomy and generate ultrasound data based on reflections of the ultrasound from the patient anatomy;
a patient-worn registration system configured in at least a one-way communication with an interventional instrument; and
a processor system implemented to:
determine, based on the ultrasound data and positional data of the ultrasound scanner, a first location of the patient anatomy relative to the patient-worn registration system;
determine, based on the at least a one-way communication, a second location of the interventional instrument relative to the patient-worn registration system; and
determine, based on the first location and the second location, a third location of the interventional instrument relative to the patient anatomy; and
a display device configured to display a depiction of the patient anatomy based on the ultrasound data and a visual representation of the interventional instrument at the third location.
