Abstract
Official abstract text for this publication.
A system and method for registering three-dimensional images with two-dimensional intra-operative images includes segmenting ( 24 ) a tubular structured organ in a three-dimensional image of the organ, and projecting ( 26 ) the three-dimensional image of the organ into two-dimensional space to provide a projected image. A medical instrument depicted in a two-dimensional image of the medical instrument is segmented ( 28 ). A similarity score is computed between the projected image and a shape of the medical instrument depicted in the two-dimensional image to determine a best match. The projected image is registered ( 30 ) to the two-dimensional image based on the best match.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for registering three-dimensional images with two-dimensional intra-operative images, comprising acts of: segmenting a tubular structured organ in a three-dimensional image of the organ; projecting the three-dimensional image of the organ into two-dimensional space to provide a projected image; segmenting a medical instrument depicted in a two-dimensional image of the medical instrument; and registering the projected image of the organ t…
