Diagnostic Imaging Common Services (DI CS)

The Diagnostic Imaging Common Service initiative enables and supports sharing and viewing of diagnostic imaging results across Ontario to all hospital and community-based health care providers anytime, anywhere, using the tools best suited to their work practices. 

What is it?

Ontario has four Regional Diagnostic Imaging Repositories (DI-rs) that allow for storage, retrieval, and sharing of diagnostic reports and images within their respective regions. All hospitals that perform diagnostic imaging are integrated with a regional DI-r, as are many Independent Health Facilities (private for-profit Diagnostic Imaging clinics). The DI-rs act as the long-term archive for storing images for many of these organizations. In support of sharing and viewing of diagnostic images in Ontario, the DI-rs publish reports to eHealth Ontario and facilitate access to the regionally stored images.


Provincial access to digital health imaging studies includes:


  • DI Common Service (DI-CS), Provincial Diagnostic Imaging (DI) Viewer
  • ClinicalConnect Clinical Viewer (Live with reports; images to be available Q1 2018/19)
  • ConnectingOntario ClinicalViewer (Q2 2018/19)

Diagnostic Imaging Common Service enables and supports sharing and viewing of diagnostic imaging results across Ontario anytime, anywhere, through the health care providers access method of choice.
