Abstract
A method includes registering a first coordinate system of a fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system. A three-dimensional (3D) map of an organ of a patient is computed using the magnetic position tracking system. A field-of-view (FOV) of the fluoroscopic imaging system in the second coordinate system is calculated using the registered first and second coordinate systems. Based on the 3D map and the calculated FOV, a two-dimensional (2D) image that simulates a fluoroscopic image that would be generated by the fluoroscopic imaging system is created, and the 2D image that simulates the fluoroscopic image is displayed.

A method, comprising:
- registering a first coordinate system of a fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system;
- computing a three-dimensional (3D) map of an organ of a patient using the magnetic position tracking system;
- using the registered first and second coordinate systems, calculating a field-of-view (FOV) of the fluoroscopic imaging system in the second coordinate system;
- based on the 3D map and the calculated FOV, creating a two-dimensional (2D) image that simulates a fluoroscopic image that would be generated by the fluoroscopic imaging system;
- and
- displaying the 2D image that simulates the fluoroscopic image.
A system, comprising:
- a memory, which is configured to store a three-dimensional (3D) map of an organ of a patient, which is produced by a magnetic position tracking system;
- and
- a processor, which is configured to register a first coordinate system of a fluoroscopic imaging system and a second coordinate system of the magnetic position tracking system, to compute the 3D map using the magnetic position tracking system, to calculate a field-of-view (FOV) of the fluoroscopic imaging system in the second coordinate system using the registered first and second coordinate systems, to create a two-dimensional (2D) image that simulates a fluoroscopic image that would be generated by the fluoroscopic imaging system based on the 3D map and the calculated FOV, and to display the 2D image that simulates the fluoroscopic image.
