Previously tested harnesses

Quality Controls for medical imaging systems enable us to check the operating condition of imaging devices over time, to guarantee optimum performance and reliable patient and worker radiation protection.

BIOMEDIQA is positioned as a service provider for internal quality controls of your medical imaging devices, governed by the ANSM.

The BIOMEDIQA team has all the expertise and skills needed to work on Interventional Radiology, Conventional Radiology and Scanography equipment.

Don't lose control

BIOMEDIQA ‘s missions are based on methods inspired by project management. In this way, you retain full control over your quality controls, with complete transparency.
