Victoria General Hospital, which is a part of the Greater Victoria
Hospital Society, is a 443 bed community hospital with a full-service
medical imaging department that includes MRI. In August 1987, four
rooms (chest radiography, GI fluorography, CT, and cardiac angiography)
were connected to a Picture Archive and Communications System (PACS).
We present the experience gained from two years of study with this
prototype PACS and briefly describe its hardware and software
configuration. Reported in detail is the measured image transfer
performance of the PACS for each of the four image sources.
Conventional films require more than 150 seconds from exposure to film
availability for reporting. Using PACS, chest and GI images take 77
seconds per image from exposure to viewing, 31 secs for CT, and 40 secs
for general angiography. The elapsed times with PACS between the
various software processes for each modality, and those needed to set
up image archive folders are detailed. The present imaging equipment
at VGH, a typical community hospital, is specified and is to be
integrated into a department-wide PACS. Required PACS performance
levels relative to the clinical demands are described, and compared
with the current PACS.
The information and experience acquired by testing the VGH PACS has
been used in the planning of the full implementation of PACS at VGH
(ref. 10. Fisher et al). The next phase (3C) of PACS implementation
