VISUALIZING VOLUMETRIC IMAGE OF ANATOMICAL STRUCTURE
First Claim
1. A system for visualizing a volumetric image of an anatomical structure, the system comprising:
- an image interface for accessing image data of the volumetric image;
a display processor configured for;
i) generating a first view 4 of the volumetric image, the first view being geometrically defined by a first viewing plane intersecting the volumetric image, the first view showing a cross-section of a surface of the anatomical structure,ii) determining at least one location on the surface based on a position of an onscreen pointer;
iii) determining a local orientation of the surface within the volumetric image by analyzing the image data of the volumetric image, the local orientation being determined for the at least one location on the surface shown in the first view, andiv) based on the local orientation being determined for the at least one location on the surface, generating a second view of the volumetric image, the second view being geometrically defined by a second viewing plane intersecting the surface of the anatomical structure in the volumetric image substantially orthogonally at the at least one location on said surface; and
a display output for generating and outputting display data, the display data representing an output of the display processor.

Abstract
A system and method is provided for visualizing a volumetric image of an anatomical structure. Using a first view of the volumetric image showing a non-orthogonal cross-section of a surface of the anatomical structure, a local orientation of the surface within the volumetric image is determined, namely by analyzing the image data of the volumetric image. Having determined the local orientation of the surface, a second view is generated of the volumetric image, the second view being geometrically defined by a viewing plane intersecting the surface of the anatomical structure in the volumetric image orthogonally. Accordingly, the surface is shown in a sharper manner in the second view than would typically be the case in the first view. Advantageously, the user can manually define or correct a delineation of the outline of the anatomical structure in a more precise manner. Moreover, various other advantageously uses of such a second view exist, such as facilitating the image interpretation by the clinician, more reliable further automatic analysis, etc.
