Title: SYSTEM AND METHOD FOR TRACKING AN INTERVENTIONAL INSTRUMENT WITH FEEDBACK CONCERNING TRACKING RELIABILITY
Abstract:
A system (100) and method (190) for determining the reliability of an ultrasonic tracking device (102) includes a determination device (132) that is configured to receive signals from the ultrasonic tracking device and determine a quantity of sensors (105) of an interventional device (103) in a field of view of the ultrasonic imaging device. An evaluation device (136) correlates a quantity of the sensors in the field of view with a reliability level for the determined orientation of the interventional device and generates a control signal (142) to a feedback device. The feedback device provides feedback to the user concerning the reliability level for the orientation of the interventional device determined by the ultrasonic tracking device. The feedback may be visual and/or audible feedback.
