Abstract

The DICOM standard defines in detail how medical images can be transmitted and stored. However, there have been no precise rules on how to interpret the parameters contained in a DICOM image which deal with the image presentation. As a result, the same image frequently looks different when displayed on different workstations or printed on a film from various printers. Three new DICOM extensions attempt to close this gap by defining a comprehensive model for the display of images on softcopy and hardcopy devices: Grayscale Standard Display Function, Grayscale Softcopy Presentation State and Presentation Look Up Table. A prototype implementation of these extensions has been shown at the 1999 annual tradeshow of the Radiological Society of North America (RSNA) as part of the scientific exhibit (infoRAD). This demonstrated a simulated radiological workflow in which images were created, interpreted at a diagnostic workstation and later reviewed on a clinical workstation. Images could also be printed using DICOM Print. The prototype shows a proof of concept, i.e. that image integrity and consistency over a variety of display and print devices can be achieved and in addition, that the new DICOM extensions can be implemented relatively easily, without a significant performance penalty. The extensions allow to store all parameters defining how an image is displayed or printed in a separate DICOM object that can be managed with the existing DICOM database services. In particular, this satisfies the user's need to view images at different locations in a consistent manner, and to document the image appearance on which a diagnosis is made in softcopy environments.
