SIMULTANEOUS DUAL WINDOW/LEVEL SETTINGS FOR DISPLAY OF CT COLONOGRAPHY IMAGES

A method for processing and displaying colonography image data. First distance tissue pixels representative of tissue within a first distance of gas pixels representative of gas are processed with a first window/level setting to generate a first setting set of image pixels. Second distance tissue pixels representative of tissue within a second distance of the gas pixels are processed with a second window/level setting to generate a second setting set of image pixels. The second distance is a distance greater than the first distance. A colonography image including both the first and second setting sets of image pixels is then displayed.
