Abstract
A method of processing an image, the image having pixel data with a bit range not capable of being encoded in a selected encoding format, the method comprising: splitting the pixel data into a base channel and at least one delta channel, at least one of the base channel and the at least one delta channel capable of being encoded in the selected encoding format; encoding at least one of the base channel and the at least one delta channel; transmitting the base channel and the at least one delta channel to a client; decoding the base channel and the at least one delta channel at the client; and recombining the base channel and the at least one delta channel at the client to form the pixel data. In some embodiments, the method further comprises: applying a window level to the pixel data formed from said recombining; and displaying the window level on a display.
