Inside Sectra AB’s journey through medical imaging and secure communications

Sectra was founded in Sweden in 1978 by researchers connected to Linköping University, with its name derived from secure transmission.

How Sectra AB developed

Early work focused on secure communications before the company expanded into medical imaging IT. It developed systems for handling radiology and other diagnostic images while retaining a separate cybersecurity business serving sensitive communications.
