Abstract
Provided is a method of generating a virtual x-ray image, the method including: obtaining a 3-dimensional (3D) image of a patient; determining a projection direction of the 3D image in consideration of a position relationship between an x-ray source of an x-ray device and the patient; and generating a virtual x-ray image by projecting the 3D image on a 2D plane in the determined projection direction.
Claims12
A method of generating a virtual x-ray image, the method comprising:
- obtaining a 3-dimensional (3D) image of a patient;
- determining a projection direction of the 3D image in consideration of a position relationship between an x-ray source of an x-ray device and the patient;
- and
- generating a virtual x-ray image by projecting the 3D image on a 2D plane in the determined projection direction.
A navigation system configured to:
- obtain a 3-dimensional (3D) image of a patient;
- determining a projection direction of the 3D image in consideration of a position relationship between an x-ray source of an x-ray device and the patient;
- generating a virtual x-ray image by projecting the 3D image on a 2D plane in the determined projection direction.
A navigation method performed by a navigation system, the navigation method comprising:
- obtaining a 3-dimensional (3D) image of a patient;
- determining a projection direction of the 3D image in consideration of a position relationship between an x-ray source of an x-ray device and the patient;
- extracting a local model from the 3D image in consideration of the projection direction of the 3D image;
- and
- matching the extracted local model to an actual x-ray image obtained during a surgery performed on the patient.
