ABSTRACT:
Method and apparatus for insuring tonal consistency between radiographic images visualized on softcopy display devices (video display) or hardcopy display devices radiography film laser printer). The method of transmitting an input digital radiographic image signal over a network to insure consistent tonal matching includes the steps of producing an input digital radiographic image by a source imaging device; providing a source-to-density look-up-table (SDL) which defines the distribution of the tonal response for the source imaging device; and transmitting the input digital radiographic image signal over a network to an output radiographic image visualization device along with the source-to-density LUT. Preferably, the output device is provided with a local density-to-display LUT (LDDL), the LDDL and SDL are cascaded together to form an output device display correction table, and the transmitted digital radiographic image signal is processed with the display correction table to produce a tonally corrected visual radiographic image.
