Abstract: By one approach, a control circuit accesses planning computed tomography image information for a particular patient. The control circuit also accesses two-dimensional digital subtraction angiography image information for the particular patient. The control circuit then fuses the planning computed tomography image information with the two-dimensional digital subtraction angiography image information to provide fused image information of the patient target volume.

Abstract: An apparatus and method for generating a contour automatically based on one or more user-generated contours for a three dimensional (3D) structure. In one aspect, a method of integrating image contour generation and editing with contour interpolation and contour extrapolation is provided. Manual contour drawing and editing may be performed by a user while interpolation and/or extrapolation of contours is automatically calculated in the background. Results of the interpolation and/or extrapolation may be displayed immediately, allowing the user to easily make refinements to any contours, as needed. In one aspect, interpolated and extrapolated contours may be automatically adapted (e.g., recalculated) according to user-modifications of contours.

Abstract: A semiautomatic drawing tool is configured to generate an image segmentation contour that corresponds to a visible edge within a digital image. Individual contour points define the shape and location of the image segmentation contour, and the semiautomatic drawing tool determines the locations of these contour points based on both user input and on the location of a steep luminance gradient that corresponds to the visible edge. The semiautomatic drawing tool determines the location of a particular point of the image segmentation contour based on the current location of an input device pointer, e.g., a cursor, the location of the steepest luminance gradient, and the location of previously selected points of the image segmentation contour.
