Method and apparatus for calibrating and re-aligning an ultrasound image plane to a navigation tracker

摘要

The present disclosure relates to acquiring image data of a subject with an imaging system that has been calibrated. The imaging system can include an ultrasound imaging system that collects one of more images based on a plane of image acquisition. The plane of image acquisition can be calibrated to a tracking device associated with the ultrasound transducer.

主权项

1. An imaging verification system, comprising:
a verification device, including:
a rigid member having an imaging system holding region fixed relative to the rigid member;a verification tracking device fixed at a selected location relative to the rigid member; an imaging system including:
a transducer configured to generate an image plane in which an object is imaged;an imaging system tracking device connected relative to the transducer at a first position, wherein the imaging system is fixable relative to the verification device at a first time, wherein the imaging system further has a calibrated navigation imaging plane at a selected location, and wherein the navigation imaging plane is at a known location relative to the imaging system tracking device fixed to the imaging system; a tracking system operable to track the verification tracking device and the imaging system tracking device at least at the first time; and a processor system; a memory system; wherein the processor system is configured to execute instructions to determine a verification plane at a determined verification location of the navigation imaging plane relative to the verification device based on the tracked location of both the imaging system and the verification device at the first time, wherein the verification plane includes at least one of a location of the image plane of the imaging system relative to the verification device or a location of the imaging system tracking device relative to the verification tracking device; and wherein the determined verification imaging plane is saved with the memory system; wherein the imaging system is removable from the verification device and operable to be fixed at the selected location relative to the verification device at a second time after the first time; wherein the tracking system is configured to track both the imaging system tracking device fixed relative to the imaging system and the verification tracking device fixed relative to the verification device at the second time to determine an imaging plane location at the second time; and wherein the processor system is configured to execute instructions to determine if the imaging plane location at the second time matches the verification plane within a threshold difference.
