NAVIGATION WITH 3D LOCALIZATION USING 2D IMAGES
First Claim
1. A method for facilitating a medical or surgical procedure in an operating site in a body of a patient, the method comprising:
- displaying a first point on a first two-dimensional image of the operating site into which an elongate, flexible catheter device is inserted in response to a first user input;
mapping the first point on at least a second two-dimensional image of the operating site, the second two-dimensional image being oriented at a non-zero angle with respect to the first two-dimensional image;
displaying a first line on the second image that projects from the first point;
displaying a second point on the second image in response to a second user input; and
determining a three-dimensional location within the operating site, based on the first line and the second point on the second image.

Abstract
A method for facilitating a medical or surgical procedure in an operating site in a body of a patient may involve: displaying a first point on a first two-dimensional image of the operating site into which an elongate, flexible catheter device is inserted in response to a first user input; mapping the first point on at least a second two-dimensional image of the operating site, the second two-dimensional image being oriented at a non-zero angle with respect to the first two-dimensional image; displaying a first line on the second image that projects from the first point; displaying a second point on the second image in response to a second user input; and determining a three-dimensional location within the operating site, based on the first line and the second point on the second image.

19. A system for facilitating a medical or surgical procedure in an operating site in a body of a patient, the method comprising:
-
an elongate, flexible catheter device; and a visualization system, comprising; a user interface for accepting user inputs related to locations of items on at least two displayed images; an image generator configured to generate images of at least a first point on a first image of the operating site and a second point on a second image of the operating site in response to the user inputs, wherein the first image is acquired via an imaging modality, and wherein the second image has an orientation that is different from an orientation of the first image; and a processor configured to map the first point on the first image with an equivalent first point on the second image, generate a first line for display on the second image that projects from the first point, and determine a three-dimensional location within the operating site, based on the first line and the second point on the second image. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
