Abstract
Disclosed herein is a system, apparatus and method directed to placing a medical instrument in a patient body, where the system includes the medical instrument having a first optical fiber, a console and an interconnect having a second optical fiber to receive incident light from the console and propagate the incident light to the medical instrument. The interconnect includes a predetermined bend along its length, such that logic of the console may determine a positioning and an orientation of the medical instrument relative to the predetermined bend. Additionally, the logic may generate a display of the medical instrument based on the reflected light signals and the determination of the positioning and the orientation of the medical instrument relative to the predetermined bend, where the display may be rendered as an overlay on an ultrasound image.
