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, which is produced by the magnetic position tracking system, is displayed. A 3D volume that would be irradiated by the fluoroscopic imaging system is calculated using the registered first and second coordinate systems. The calculated 3D volume is marked on the 3D map.
Claims8
A method, comprising;
- registering a first coordinate system of a fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system;
- displaying a three-dimensional (3D) magnetic position tracking map of an organ of a patient, which is produced by the magnetic position tracking system;
- calculating, based on aligned coordinates of the registered first and second coordinate systems, a 3D volume that would be irradiated by the fluoroscopic imaging system according to a direction in which the fluoroscopic imaging system is pointing;
- and
- marking the calculated 3D volume on the 3D magnetic position tracking map.
2 more elements
A system, comprising;
- an interface, which is configured to communicate with a fluoroscopic imaging system;
- and
- a processor, which is configured to register a first coordinate system of the fluoroscopic imaging system and a second coordinate system of a magnetic position tracking system, to display a three-dimensional (3D) magnetic position tracking map of an organ of a patient, which is produced by the magnetic position tracking system, to calculate, based on aligned coordinates of the registered first and second coordinate systems, a 3D volume that would be irradiated by the fluoroscopic imaging system according to a direction in which the fluoroscopic imaging system is pointing, and to mark the calculated 3D volume on the 3D magnetic position tracking map.
