METHOD AND APPARATUS FOR REGISTRATION, VERIFICATION AND REFERENCING OF INTERNAL ORGANS

摘要

Systems and methods for registering, verifying, dynamically referencing, and navigating an anatomical region of interest of a patient are provided. In one embodiment, the anatomical region of interest is imaged using an imaging device such as, for example, an x-ray device. A tracked registration device may then be removably inserted following a path within the anatomical region and the position of the registration device may be sampled by a tracking device as the registration device is moved within the anatomical region through the catheter. The sampled position data is registered to the image data to register the path to the anatomical region of interest. The same or a similar device may be used to dynamically reference the movements affecting the anatomical region and modify the registration in real time. The registration may also be verified.

主权项

1. A system for registering an anatomical region of a patient, comprising: an imaging device configured to produce image data of the anatomical region of the patient including coordinate information in a first frame of reference; a registration device including at least one position indicating element, wherein the registration device is configured to follow a path within the anatomical region of the patient set out in the image data coordinate information; a tracking device adapted to produce position data regarding a followed path within the anatomical region in a second frame of reference, wherein the position data is obtained by the tracking device sampling coordinates of the at least one position indicating element as the position indicating element is moved within the image data coordinate information path of the anatomical region of the patient; t and a computer element having a processor, wherein the processor is adapted to receive the image data from the imaging device, receive the position data from the tracking device, and map the image data path and the position data followed path together.
