1. A medical-device visualization system for visualizing an elongate medical device in a body of a patient, comprising:
a stylet including:
an optical fiber along a length of the stylet, the optical fiber having a plurality of optical-fiber sensors distributed along a length of the optical fiber; and
a field generator in at least a distal tip of the stylet;
a plurality of patient-wearable sensors, each sensor of the plurality of patient-wearable sensors configured to sense a field generated by the field generator; and
a console with electronic components and circuitry including memory and one or more processors, the memory including executable instructions configured to instantiate medical-device visualization processes upon execution by the one or more processors for visualizing the elongate medical device by way of the stylet disposed therein as the elongate medical device is advanced through a vasculature of the patient, and the medical-device visualization processes including:
a shape-sensing process that utilizes shape-sensing logic for determining a shape of the stylet in real-time from reflected optical signals reflected by the plurality of optical-fiber sensors;
a registration process that utilizes registration logic for registering the distal tip of the stylet in real-time at each sensor of the plurality of patient-wearable sensors; and
a reference-framing process that utilizes reference-framing logic for placing the stylet with its shape in a patient-based reference frame established by the plurality of patient-wearable sensors.
