1. A medical device tip-tracking system, comprising:
a light-emitting stylet configured to be disposed in a lumen of a medical device, the light-emitting stylet configured to emit light from a distal-end portion of the light-emitting stylet;
a light detector configured to be placed over and external to a patient, the light detector including a plurality of photodetectors configured to detect the light emitted from a light source, wherein the plurality of photodetectors are arranged in the light detector such that the plurality of photodetectors are configured to detect a remaining portion of the light when a first portion of the light is anatomically blocked by a bone of the patient; and
a console coupled to the light-emitting stylet and the light detector, the console including:
a processor, and
non-volatile memory storing instructions that, when executed by the processor, cause performance of operations including:
displaying tracking information in a graphical user interface on a display screen as the light-emitting stylet is advanced through a vasculature of the patient.
