Abstract

A controller for determining shape of an interventional device includes a memory that stores instructions, and a processor that executes the instructions. When executed by the processor, the instructions cause the controller to execute a process that includes controlling an imaging probe to emit at least one tracking beam to an interventional medical device over a period of time comprising multiple different points of time. The process also includes determining a shape of the interventional medical device, based on a response to the tracking beams received over the period of time from a first sensor that moves along the interventional medical device during the period of time relative to a fixed location on the interventional medical device for the period of time.
