Abstract
A controller (240/340) for simultaneously tracking multiple interventional medical devices includes a memory (242/342) that stores instructions and a processor (241/341) that executes the instructions. When executed by the processor (241/341), the instructions cause the controller to execute a process that includes receiving timing information from a first signal emitted from an ultrasound probe (252/352) and reflective of timing when the ultrasound probe (252/352) 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 (232/332). The first acquisition electronic component (232/332) also receives sensor information from a first passive ultrasound sensor (S1) on a first interventional medical device (212/312). The timing information is used to synchronize the sensor information from the first passive ultrasound sensor (S1) on the first interventional medical device (212/312) with sensor information from a second passive ultrasound sensor (S2) on a second interventional medical device (216/316).
