Fused-image visualization for surgery evaluation

摘要

Disclosed herein is a framework for facilitating fused-image visualization for surgery evaluation. In accordance with one aspect of the framework, at least one pre-operative image and at least one intra-operative image of an anatomical structure are received. A region of interest may be identified in the intra-operative image. The pre-operative image may be straightened, and a symmetric region may be identified in the straightened pre-operative image. The symmetric region is substantially symmetrical to a target region in the straightened pre-operative region. The target region corresponds to the region of interest in the intra-operative image. The symmetric region may be extracted and reflected to generate a reference image. The intra-operative image may be rigidly registered with the reference image to generate registered intra-operative image, which is overlaid on the target region in the straightened pre-operative image to generate a fused image.

1. A computer-implemented method of visualization, comprising:
(i) receiving at least one pre-operative image and at least one intra-operative image of an anatomical structure; (ii) straightening the pre-operative image to generate a straightened pre-operative image; (iii) identifying a region of interest in the intra-operative image; (iv) identifying a symmetric region in the straightened pre-operative image based on the intra-operative image, wherein the symmetric region is substantially symmetrical to a target region in the straightened pre-operative image, wherein the target region corresponds to the region of interest in the intra-operative image; (v) extracting the symmetric region from the pre-operative image and reflecting the extracted symmetric region to generate a reference image; (vi) rigidly registering the intra-operative image with the reference image to generate a registered intra-operative image; and (vii) overlaying the registered intra-operative image on the target region in the straightened pre-operative image to generate a first fused image.
