Abstract
A registration method whereby a sensor-based approach is used to establish initial registration and whereby upon the commencement of navigating an endoscope, image-based registration methods are used in order to more accurately maintain the registration between the endoscope location and previously-acquired images. A six-degree-of-freedom location sensor is placed on the probe in order to reduce the number of previously-acquired images that must be compared to a real-time image obtained from the endoscope.
Claims1
A method of registering sensor location data to images of at least one body lumen, comprising:
- placing a probe including a sensor disposed thereon relative to at least one body lumen in a patient;
- generating location data corresponding to the sensor;
- registering a location of the sensor relative to a previously acquired image selected from a plurality of previously acquired images of the at least one body lumen based on the location data;
- generating a subgroup of the plurality of previously acquired images based on the location data;
- and
- updating the registered location of the sensor based on an image selected from the sub-group.
