Abstract:
Described embodiments include a processor that receives signals from a probe, as the probe is placed at respective locations on a body of a subject, and derives, from the signals, a set of points that correspond to the respective locations. The processor then registers the set of points with a three-dimensional image of the body, by identifying, for each of the points, one or more voxels of the image whose respective surface normals are oriented within a given angle of an orientation at which the probe was held at the location to which the point corresponds, and computing a transformation that aligns each of the points with a selected one of the voxels that were identified for the point. The processor then tracks, based on the registering, a location of an intrabody tool, in a coordinate system of an imaging device that was used to acquire the image.

Claim (Index 21):
A system, comprising:\n (a) a probe interface; and (b) a processor, configured:\n (i) to receive, via the probe interface, a plurality of signals from a probe, as the probe is placed at respective locations on a body of a subject, wherein the probe is positioned at respective orientation axes at each the respective locations, such that each location has a corresponding probe orientation axis, \n (ii) to derive, from the plurality of signals:\n (A) a set of points that correspond to the respective locations, and \n (B) the probe orientation axes associated with the respective locations, \n \n (iii) to register the set of points with a three-dimensional image of at least a portion of the body of the subject, wherein the three-dimensional image comprises a set of voxels, each voxel having an associated surface normal, wherein the processor is configured to register the points by:\n (A) identifying a set of candidate voxels from the set of voxels based on the probe orientation axis at that point, and the surface normal of those voxels, and \n (B) computing a transformation that aligns that point with a voxel of the set of candidate voxels.
