Small Specs
Dual source computed tomography system 
225 kV and 450 kV X-ray source 
2048 * 2048 pixel flat panel detector 
5 µm min. voxel size


The Dual Source computed tomograph 250E was installed at the FHOÖ Wels Campus in November 2004. The device has two X-ray sources: the microfocus X-ray source Viscom XT9225 DED is suitable for high-resolution measurements, the minifocus X-ray Comet MXR-451HP/11 for high penetration lengths. The detector implemented is an a-Si (amorphous silicon) detector type PerkinElmer XRD 1620 AN14 CTS converting X-rays via a    scintillation layer into visible light. The technical data on the device is listed below:

  • 225-kV-microfocus- and 450-kV-minifocus tube
  • 2048 * 2048 pixel 16 bit a-Si flat panel detector
  • Minimum voxel size: 5 µm (max. sample diameter / 2048)
  • Sample weight < 80 kg
  • Sample diameter < 310 mm (with scan range enlargement < 600 mm)
  • Sample length <1,8 m
  • Maximum penetration length microfocus 225 kV: polymers - max. 200 mm, aluminium - max. 120 mm, steel - max. 30 mm
  • Maximum penetration length minifocus 450 kV: polymers - max. 500 mm, aluminium - max. 250 mm, steel - max. 70 mm
  • "Region of Interest" measurement mode for flat components
  • Radioscopy mode with up to 7 fps
