Abstract
Laser film digitizers, interactive gray-scale monitors, and laser film printers are necessary to transmit digital image information. These devices must be standardized so that hard- and soft-copy images are as similar as possible. Standardization of appropriate calibration procedures is necessary to attain this goal. Radiographs are converted into digital data representations by a laser film digitizer. These representations (and those obtained with other modalities) are transferred to a laser film printer or to an interactive monitor with gray-scale display. To obtain the best gray-level fidelity, printer output optical densities should be identical to those of the input film. Laser printers should be calibrated regularly to ensure uniform results. A gray-scale controller functions as an adjunct to the host computer and can automate the calibration process. Gray-scale controller functions may someday be incorporated into an accelerator or array-processor board.
