SYSTEMS AND METHODS FOR PERFORMING LOCALIZATION WITHIN BODY

Provided herein are systems and methods for performing localization within a patient. A method of localization within a body comprises providing at least one processor coupled to at least one data storage device, establishing and calibrating a localization coordinate system within a body by executing a first localization mode by the at least one processor, recalibrating the localization coordinate system by executing a second localization mode by the at least one processor, and localizing a device within the localization coordinate system using the first localization mode and the second localization mode, by the at least one processor. The first localization mode can be an impedance-based localization mode and the second localization mode can be magnetic-based localization mode, or vice versa. 本发明提供了用于在患者体内进行定位的系统及方法。一种体内定位方法包括：提供耦合到至少一个数据存储设备的至少一个处理器；通过至少一个处理器执行第一定位模式来建立和校准体内定位坐标系；通过至少一个处理器执行第二定位模式来重新校准定位坐标系；至少一个处理器使用第一定位模式和第二定位模式来在定位坐标系内定位设备。第一定位模式可以是基于阻抗定位模式而第二定位模式可以是基于磁性定位模式，反之亦然。
