Abstract:
:A group of experts on very large databases, quantitative imaging, data format standards development, image management and communications, and related technologies for cancer imaging met at a recent workshop sponsored by the BIP and discussed the key issues confronting this field. The BIP received recommendations regarding steps that can be taken to advance the technology and take advantage of the opportunities to improve collaboration and utility in cancer imaging. There are tremendous opportunities to change radically the way we use image information. These opportunities are most obvious in clinical research, in which we seek to advance the dissemination and use of cancer image data in research and practice. Important opportunities and new modes of information use are provided by supporting the entire "information cycle" of creation, dissemination, and collaboration in addition to image organization, access, presentation, and preservation. To learn more, visit the BIP Web site at www3 .cancer.gov/bip/steer_iasc.htm and join the image archive listserver at the NIH (ARCHIVE-COMM-L, available online at list.nihgov). These resources are open and available to all.
