Windsor Regional Hospital continues to bring systems back online as it recovers from the criminal cyber attack nearly 11 weeks ago.
This week, the system that electronically stores images and reports from diagnostic imaging tests like X-rays, CTs or ultrasounds is back up and running.
Chief Operating Officer Karen Riddell says the hospital was always completing urgent scans but can now continue with semi-urgent cases.
"Now that PACs [the electronic image storage system] is up and running we'll be able to ramp up as early as next week with our P3s [semi-urgent priority cases] and expect that we'll be able to get through our backlog of P3s within approximately 10 weeks," said Riddell.
Other systems that still need to be fully restored are the meal order software, automated medication dispensing cabinets and the cardiovascular information system.
The hospital will remain in a "code grey" until these systems are restored.
"The next couple of weeks will be key because then our main clinical items will be back up," said David Musyj, CEO of WRH.
