Abstract
A method and system for reducing divergence between computed tomography images and a patient using three-dimensional reconstructions. The method utilizes cone beam imaging or three-dimensional fluoroscopy to supplement or supplant pre-operative computed tomography imaging.
Claims17
A method for registering an image to a luminal network comprising:
- receiving a pre-operative computed tomography (CT) image of the luminal network;
- receiving an indication of a target within the luminal network;
- generating a pathway through the luminal network to the target;
- generating a CT 3D model from the pre-operative CT image;
- detecting a position of a catheter within the luminal network;
- registering the pre-operative CT image to the detected position of the catheter;
- receiving an indication of a location of a sensor in the pre-operative CT image or CT 3D model and updating the location in a user interface until proximate the target;
- receiving cone-beam computed tomography (CBCT) images of the luminal network;
- and
- identifying a position of the catheter in the CBCT images and updating the location of the sensor in the pre-operative CT image or CT 3D model in the user interface.
