RayScan 250E
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
