A simple and inexpensive solution for the complete digital management of a nuclear medical institution is presented. The starting point was provided by five different gamma cameras, one of which was equipped with a PC-based ICON computer. The remaining cameras were first adapted to ICONs and subsequently integrated into a Macintosh LAN, of 15 computers, allowing the entire image acquisition, processing, interpretation, documentation and archiving to be performed on the same comfortable menu-guided surface. Complete patient management is accomplished by a specific commercially available data base to which a specially developed image and document archive was connected. The system described provides complete digital management without the conventional filing systems at the moderate price of approximately DM 11 x 10(4) plus the cost of the new camera computers.
