1. A method for reformatting image data, comprising: obtaining volumetric image data indicative of an anatomical structure of interest; identifying a surface of interest of the anatomical structure of interest in the volumetric image data; identifying a thickness for a sub-volume of interest of the volumetric image data; shaping the sub-volume of interest such that at least one of its sides follows the surface of interest; and generating, via a processor, a maximum intensity projection (MIP) or direct volume rendering (DVR) based on the identified surface of interest, the shaped sub-volume of interest, and the side the follows the surface of interest.
