G-force test gantry
Philips Medical Systems, Hamburg
A dedicated test gantry has been developed for testing and verification of X-Ray modules used in CT Scanners. The gantry applies centrifugal forces for overload testing and accelerated lifetime testing of modules.
At Philips Medical Systems in Hamburg, X-ray components for CT Scanners are developed and produced. The next generation CT Scanners will rotate at a higher speed that will expose its internal components to higher centrifugal forces. Regulations state that before application in a medical environment all components need to be tested with a factor 4 mechanical overload. In order for Philips to continue selling certified medical systems in the future, MI-Partners has developed a test device. This G-force test gantry is capable of applying these extremely high centrifugal forces in a safe way. MI-Partners carried out a turn-key project starting with the specifications up to installation and validation testing of the device on site. See the Video.
