US 10,013,777 B2 · System and method for generating partial surface from volumetric data for registration to surface topology image data

Abstract

The present disclosure relates to the generation of partial surface models from volumetric datasets for subsequent registration of such partial surface models to surface topology datasets. Specifically, given an object that is imaged using surface topology imaging and another volumetric modality, the volumetric dataset is processed in combination with an approach viewpoint to generate one or more partial surfaces of the object that will be visible to the surface topology imaging system. This procedure can eliminate internal structures from the surfaces generated from volumetric datasets, thus increases the similarity of the dataset between the two different modalities, enabling improved and quicker registration.

Dependent claims

A computer implemented method of performing image registration between volumetric image data associated with an object and surface topology image data associated with the object, wherein the surface topology image data is obtained by a surface topology imaging system, the method comprising:

obtaining spatial information associated with the orientation of the surface topology imaging system relative to the object;
processing the volumetric image data and the spatial information to generate one or more partial surfaces oriented toward the surface topology imaging system, such that the one or more partial surfaces exclude surface data hidden from the surface topology imaging system;
and
employing the one or more partial surfaces to perform image registration between the volumetric image data and the surface topology image data, thereby identifying a transformation between the volumetric image data and the surface topology image data.
