A comparative study of C-RAD’s GEMiniTM detector system to existing systems.

Press release 2009-03-05

A comparative study of C-RAD's GEMiniTM  detector system to existing systems.


C-RAD AB with its three fully owned subsidiaries develops new and innovative
solutions for the use in advanced radiation therapy.  The subsidiary C-RAD
Imaging has with a very tight time schedule developed the first detector
system, based on the unique GEM technology, for use in radiation therapy. A
first comparative study in cooperation with the Karolinska Institutet in Solna
Sweden is showing better or similar results than with existing detector
systems. The design will be further optimized for use in radiation therapy and
industrial applications. 

The GEMiniTM family of image detector panels is primarily designed for use in
radiation therapy but the panels can also be used in industrial radiography
systems. The market potential for C-RAD Imaging's GEM technology is at least
150 MUSD per year. GEMiniTM products represent world class performance and
comprise state of the art technology including new unique patented inventions.
These new inventions enable superior image quality and real time detection
combined with lower cost of ownership. 

In cooperation with the Karolinska Institutet in Solna a comparative study has
been performed with the detector system used by two of the largest vendors in
radiation therapy, Varian and Elekta. For the study a standard so called QC3
phantom were used. Positioning of the phantom, the energy and the dose were the
same to compare the three detector systems. The C-RAD GEMini ED is showing
better or similar contrast and resolution than the detector systems of Varian
and Elekta. The tests have been running at the University Hospital in Lund and
at RayClinic outside of Uppsala. For information about comparative data see 

In parallel tests were accomplished with HITEC, a company working with
industrial applications. The test objects were placed behind 12 cm of steel.
Requirements were fulfilled. Integration work and tests with end customers will
start in Q2 2009. 


Erik Hedlund, CEO, C-RAD AB:

” The C-RAD Imaging group located outside of Östersund has presented
outstanding results with the GEMini technology. Presented results are highly
competitive. The design will during coming months be optimized for use in
different applications. The commercialization of the GEMini detector will be
intensified. The approval by HITEC is encouraging for all C-RAD employees. “
