Abstract

A method and system for translating two dimensional (2D) mapping into a three dimensional (3D) derived model. The method and system receive electrical measurements from a plurality of electrodes of the basket catheter of an anatomical region of interest. The method and system receive a 2D map grid based on the electrodes and corresponding spines of the basket catheter. The 2D map grid includes a location of at least one focus of an arrhythmic rotor. Further, the method and system generate a 3D derived model of the anatomical region of interest that includes the basket catheter and display a 3D location of the focus the arrhythmic rotor on the 3D derived model based on the 2D map grid.

generating a 3D derived model of the anatomical region of interest that includes the basket catheter; and
displaying a 3D location of the focus of the arrhythmic rotor on the 3D derived model based on the 2D map grid.

2. The method of claim 1 , further comprising acquiring a 2D image of the anatomical region of interest that include the basket catheter; and
acquiring a 3D model of the anatomical region of interest, wherein the 3D derived model is based on the 2D image and the 3D model.

3. The method of claim 2 , further comprising acquiring the 3D model from at least one of a CT imaging system, an MR imaging system, or a 3D rotational angiography;
determining a volume of the anatomical region of interest based on the 3D model; and
selecting the basket catheter from a plurality of basket catheters based on the volume of the anatomical region of interest.

4. The method of claim 2 , further comprising acquiring the 2D image from a fluoroscopy imaging system.

5. The method of claim 2 , further comprising acquiring a second 2D image, wherein the 3D derived model is further based on the second 2D image.

6. The method of claim 1 , further comprising displaying the 2D map grid; and
