We are Thirona

  • The name Thirona comes from the celtic goddess named Thirona, worshipped for healing. Although more commonly spelled as Sirona in the Latin alphabet, the spelling Thirona was chosen to reflect our roots in thoracic image analysis.

Who are we?

Thirona was founded in 2014 by Eva van Rikxoort and Bram van Ginneken, both scientists at the Radboud University Medical Center in Nijmegen, the Netherlands. Our vision was that the gap between academic developments in medical image analysis and clinical useability needs to be bridged by creating products that include the latest technologies but at the same time are intuitive for the user and aid medical specialists in their daily tasks.

Since its establishment in 2014, Thirona has quickly grown from a real start-up with two employees to a well established company with over 20 employees.

What do we do?

Since its establishment in 2014, Thirona has developed three software products focusing on the analysis of thoracic CT scans (LungQ), chest X-rays (CAD4TB), and retinal images (RetCAD). Next to that, Thirona offers a certified image analysis service delivering accurate and repeatable measurements from medical images. Thirona operates under ISO 13485 certification.
