Abstract

The importance of remote access to both radiological images and medical information has stimulated many demonstration projects utilizing a variety of telecommunications providers' offerings. Teleradiology over modest cost channels can achieve adequate response times using a combination of narrow-band ISDN and data compression. A demonstration project, developed in collaboration with Southwestern Bell Technology Resources, Inc., utilizes the aggregate bandwidth of two B channels (achieving a rate of 120 kb/s) and a compression/ decompression implementation based on the JPEG block-oriented DCT approach. System response measurements for an Inquiry and Display Station accessing the Mallinckrodt Institute of Radiology's (MIR) Radiology Image and Information Management (RIM) Testbed via the N-ISDN connection shows response times to be within 20 seconds. Viewing applications have been demonstrated at sites within St. Louis and at RSNA-90 in Chicago. Image quality metrics and observations are presented for a sample digitized film chest radiograph and computed radiographs of portable x-ray examinations vis a demonstration at the poster session.
