Initially, the objective is to set-up an audio-visual telereferral conference unit specifically for respiratory medicine based radiology CT image tertiary referrals, to trial the demand and benefit using four identified sites and assess the degree of improvement this system provides with a view to expansion.  The audio link is achieved by conference phonetechnology, the visual images are transmitted via ISDN using whatever equipment the referring site possess.  (Radworks, Winrad, Acess, etc) in Dicom3 format.  We have MagicView50 (Siemens) installed on a PC, in such a way that we believe, with interconnectivity and compression set-up correctly, we will be able to receive and translate regardless of proprietoriality thus overcoming the incompatibility issues.  In addition, we will provide the facility to transfer the images, to the PACS system (Siemens) utilitsing all the associated advantages and advances.  Our aim is to "share medical expertise" which we feel is available though not readily accessible at the moment yet maintain continuity by continuing current working practice at the referring end rather than a technology driven enterprise.  Unless the benefit is patient focussed the project will be terminated.
