SYSTEM AND METHOD FOR DETECTING SPHERICAL AND ELLIPSOIDAL OBJECTS USING CUTTING PLANES

摘要

A method for detecting spherical and ellipsoidal objects is digitized medical images includes providing (81) a 2-dimensional (2D) slice I(x, y) extracted from a medical image volume of a colon, said image volume comprising a plurality of intensities associated with a 3 grid of points, generating (82) a plurality of templates of different sizes whose shape matches a target structure being sought in said slice, calculating (83) a normalized gradient from said slice, calculating (84) a diverging field gradient response (DFGR) for each of the plurality of masks with the normalized gradient, and selecting (85) a strongest response as being indicative of the position and size of the target structure.
