1. A system for tracking location of an interventional medical device in an interventional medical procedure, comprising:
an interface to an optical shape sensing device which has a shape that conforms to a shape of the interventional medical device during the interventional medical procedure; and
a controller comprising a memory that stores instructions and a processor that executes the instructions, wherein, when executed by the processor, the instructions cause the system to:
identify the shape of the optical shape sensing device using optical shape sensing signals received from the optical shape sensing device via the interface;
identify the interventional medical device in a first coordinate space of a first imaging system that images the interventional medical device in a first imaging mode during the interventional medical procedure, based on identifying the shape of the optical shape sensing device;
register the interventional medical device to the first coordinate space;
identify the interventional medical device in a second coordinate space of a second imaging system that images the interventional medical device in a second imaging mode during the interventional medical procedure;
register the first coordinate space of the first imaging system to the second coordinate space of the second imaging system;
segment the interventional medical device in the second coordinate space to obtain a segmented representation of the interventional medical device in the second coordinate space;
register the interventional medical device to the second coordinate space using the segmented representation of the interventional medical device; and
re-register the interventional medical device to the first coordinate space based on registering the interventional medical device to the second coordinate space.
