presenting tomographic image data as an image in a viewport using a set of global image processing operations; presenting a viewing window in the viewport; and using, by a processor, a second, different set of image processing operations for the viewing window, wherein the second, different set of image processing operations reduces image artifact with respect to a desired structure of interest in the viewing window, wherein the second, different set of image processing operations includes a window width value and a window level value that correspond to a CT number indicative of the structure of interest, wherein the window width defines a range of CT numbers about the window level and the window level is a gray level that places the CT number indicative of the structure of interest within the window width, and wherein the window width value and the window level value of the viewing window is different from a window width value and a window level value of the viewport, wherein the viewing window is presented in the viewport at a location automatically determined based on the CT number. |
