Abstract
A medical system including a catheter or other flexible structure uses a combination of two different sensor systems to measure a pose of a section or tip of the catheter or flexible structure. The first sensor system, which may include an electromagnetic sensor, can measure a pose of a first section of the catheter, and the second sensor system can measure a pose of the second section relative to the first section. The second sensor system may employ a technology such as fiber shape sensing that permits the second section to be smaller than the first section, so that a distal tip of the catheter or flexible structure can fit within smaller natural lumens.
