Abstract

As Picture Archiving and Communication System (PACS) technology has matured, video image capture has become a common way of capturing digital images from many modalities. While digital interfaces, such as those which use the ACR/NEMA standard, will become more common in the future, and are preferred because of the accuracy of image transfer, video image capture will be the dominant method in the short term, and may continue to be used for some time because of the low cost and high speed often associated with such devices. A series of digital phantoms has been developed for display on either a CT9800 or Hilite Advantage scanner. The phantom images have been stored on magnetic tape in the standard tape archive format used by General Electric, so that the images may be loaded onto the scanner at any time. These images are then captured using a commercial video image capture board in a PC/286 computer, where the images are not only to be displayed, but also analyzed with the use of an automated process implemented in a computer program on the same PC. Results of the analyses are saved, together with the data and time of image acquisition, so that the results can be displayed graphically, as trend plots.
