Spiral Scanning Technique

Ultra-fast scanning technique with continuous table feed. Up to 80 mm/s volume coverage for minimized examination times for live animals. Data acquisition of an entire anatomical volume up to 157 cm without pause. Maximum Table Load 200 kg / 450 lbs. Maximum Gantry Aperture 70 cm. Maximum Specimen Diameter (with table in gantry) 60 cm. Slice Thickness/Collimation 0.5 mm - 10 mm. Slice Increments 0.1 mm - 10 mm. (increment is the distance between the center of adjacent images.) Table Pitch 1 - 8. (pitch is the ratio of table feed per rotation to collimation of a single slice.) Topogram Data: Min/Max Length: 128/1024 mm. Min/Max Time: 1.6/10.6 sec. Views: Anterior to Posterior (AP), Posterior to Anterior (PA), Lateral (LAT).

Sequence Scanning Technique

• Ultra fast acquisition with or without table feed.
• Automatic clustering of scans.
