<p>One embodiment of the present invention is a method for interactively rotating a sampling surface of a reconstructed computed tomographic (CT) image (50). The method includes steps of: scanning a volume of a patient (22) to collect a plurality of slices of image data; displaying an image slice including a structure of interest (52) on a display (42); defining a segmented line approximating a centerline of the structure of interest; selecting a rotation vector, a reference vector, and an angle; generating a sampling vector as a function of the rotation vector, the reference vector, and the selected angle; and generating a curved reformation image (54) from the plurality of slices of image data using the segmented line and the sampling vector.</p> |
