Synchronized tracking of multiple interventional medical devices

Abstract

A controller () for simultaneously tracking multiple interventional medical devices 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 receiving timing information from a first signal emitted from an ultrasound probe () and reflective of timing when the ultrasound probe () transmits ultrasound beams to generate ultrasound imagery. The process executed by the controller also includes forwarding the timing information to be available for use by a first acquisition electronic component (). The first acquisition electronic component () also receives sensor information from a first passive ultrasound sensor (S) on a first interventional medical device (). The timing information is used to synchronize the sensor information from the first passive ultrasound sensor (S) on the first interventional medical device () with sensor information from a second passive ultrasound sensor (S) on a second interventional medical device ().
