1. A shape-sensing system, comprising:
an integrated optical-fiber stylet having a plurality of fiber Bragg grating (“FBG”) sensors along a distal-end portion of the integrated optical-fiber stylet;
a heartbeat-detecting device configured for detecting a sequence of heartbeats;
a console including memory and one or more processors configured to:
convert the sequence of heartbeats into a heartbeat frequency by a heartbeat-converter algorithm; and
convert FBG sensor-reflected optical signals from the integrated optical-fiber stylet into plottable data by a plurality of optical signal-converter algorithms, the plurality of optical signal-converter algorithms including a band-pass filtering algorithm for a selection of the FBG sensors along the distal-end portion of the integrated optical-fiber stylet, the band-pass filtering algorithm configured to pass therethrough the FBG sensor-reflected optical signals or corresponding data occurring with one or more frequencies within a range of frequencies around the heartbeat frequency while rejecting the FBG sensor-reflected optical signals or the corresponding data occurring with the one or more frequencies outside the range of frequencies around the heartbeat frequency; and
a display screen configured for displaying the plottable data.
