Radiation protection

Radiation protection CT MRI

Strong protection in CT radiation exposure

The eye lens belongs to the most radiosensitive organs of the human body. In a CT scan, the Commission on Radiological Protection therefore recommends sufficient protection for this organ, in particular in a CT scan of the skull. 



  • Lens protector for CT scanning
  • Substantial reduction in radiation exposure*
  • Low artefact formation due to comfortable spacers
  • Spacers consisting of 5 mm polyurethane foam
  • Material made from Antimony and Bismuth
  • Lead and latex-free
  • Non-irritating holding strips for secure hold

Reduction of radiation dose in CT up to 67%*

  • CT-Eye-ProteX 67% 67%
  • Reference product 33% 33%

In a study of the Department of Diagnostic and Interventional Radiology and Neuroradiology of the University Hospital Essen*, the potential for dose reduction of different lens protectors for patients undergoing cranial computed tomography was investigated. The SOMATEX eye protector CT-Eye-ProteX showed a higher dose reduction potential than the competitor product – while maintaining the same image quality.


  • For the CT-Eye-ProteX, an average dose reduction of 2/3 (about 67%) in CT examinations was achieved when the lens is exposed to the direct beam.
  • By comparison, the competitor product achieved an average reduction of the eye lens dose in CT examinations by 1/3 (about 33%).
  • Depending on the CT protocol, even dose reductions of 4/5 (about 80%) are achieved with the SOMATEX CT-Eye-Protex compared to the non-shielded state.
