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.
Claims1
A method of registering an image to a luminal network comprising:
- detecting a position of a sensor in a luminal network;
- receiving images for 3D reconstruction of the luminal network with the sensor within the luminal network;
- presenting a 3D reconstruction image on a user interface;
- receiving indication of location of target in the 3D reconstruction image;
- generating pathway through the luminal network to a target;
- and
- determining if the sensor moved from detected position following receipt of the images for 3D reconstruction, wherein when it is determined that the position of the sensor is the same as detected position, the luminal network and the 3D reconstruction are registered.
