Embodiment Construction

[0012] In accordance with the principles of the present invention, systems and methods are provided that employ fiber optic shape sensing and localization techniques to achieve accurate reconstruction of shape. Accurate shape data can be retrieved by "painting" structures of interest with fiber optic shape sensing enabled instruments (eg, catheters during interventional procedures, etc.).

[0013] In one embodiment, fiber optic shape sensing and localization technology can be used to acquire shape data in the form of an ultra-dense point cloud. Considering the high data rates of fiber-optic shape sensing and localization technologies and the complex topology of anatomical structures, point-based mesh processing algorithms may be inappropriate.

[0014] A system is employed that allows mapping of ultra-dense point cloud data into a voxel dataset using an index-based lookup mechanism. The voxel data may be processed using, for example, standard image processing techniques (eg, ...

Abstract

A system (100) for tagging voxels comprising: a sensing-enabled device (104) having an optical fiber (126) configured to sense induced stress within; an interpretation module (112) configured to receive signals from said optical fiber interacting with an internal organ such as a heart and interpret said signals to determine that said at least one optical fiber is in said internal A location accessed within the organ; a data source (152, 154) configured to generate data associated with an event or state, such as respiration, ECG phase, time stamp, etc.; a storage device (116) configured to store A history (136) of said location in said internal organ being visited, and associating said location with said data generated by said data source (152, 154).

Description

technical field [0001] The present disclosure relates to medical instrumentation, and more particularly to shape-sensing optical fibers in medical applications for improved curved multi-planar recombination. Background technique [0002] In many applications, it is often necessary to understand the characteristics and geometry of the internal chamber. This information may not be readily accessible through the imaging modality, or may not be readily digitized for use with software programs or analysis tools. In many instances, it is important to know the geometry of the internal chamber, or to be able to map the internal chamber digitally. [0003] Fiber optic shape sensing and localization enables accurate, time-resolved reconstruction of the shape of medical devices such as flexible catheters during interventional in vivo procedures. These device shapes can be used to better understand the anatomy being analyzed. Contents of the invention [0004] In accordance with th...
