Both are faculty members of the Diagnostic Image Analysis Group of the Radboud University Medical Center, Nijmegen, the Netherlands and Bram van Ginneken is a scientist at Fraunhofer MEVIS, Bremen, Germany. Thirona develops products that use state-of-the-art image processing techniques such as deep learning. We are ISO 13485 certified and all of our products are CE certified. Furthermore, LungQ has received 510(k) clearance.

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.
