BIR 200/150 is a DeskTop Volume Computed Tomography (VCT), Digital Radiography (DR), and Fluoroscopy system

 BIR 200/150 is a DeskTop Volume Computed Tomography (VCT), Digital Radiography (DR), andFluoroscopy system consisting of the following components, subsystems, and options:

• Quad Core Intel® Xeon™ workstation and Windows based ACTIS-5 application software• Reconstruction Accelerator• Hamamatsu 150 kV micro-focus x-ray system• Varian PaxScan 2520V amorphous silicon flat panel detector with 1408 x 1888 pixels at 127 μm• Precision servo controlled mechanics• Cabling, power supplies, and motion control system• X-ray shielded enclosure• Integration, testing, training, documentation, and one year warranty• On-site installation, set-up, and training

The system is suitable for x-ray inspection of metallic, organic, composite, plastic, and mixed items over a wide range of density and materials. The system produces cross sectional volume CT images, digital radiographic images, and fluoroscopic (live) images. In addition to density mapping, VCT provides complete 3-D morphology of parts with highly accurate dimensioning capability. VCT also provides superior flaw detection capability of extremely small cracks, porosity and voids that are not visible with film radiography or RTR inspection.

The cover photo shows a BIR 200/150 configured as a "DeskTop" system with a radiation-shieldedenclosure. The enclosure covers are situated on slide rails for easy opening and access to the partmanipulator while an integral base assures precise alignment of critical system components.

CT Spatial Resolution -2.5 μm detail detection at maximum magnification (5 μm focus, 4 watts);8 μm true spatial resolution for objects up to 6 mm diameter (7 μm focus, 10 watts);10 μm true spatial resolution for objects up to 15 mm diameter (7 μm focus, 10 watts);20 μm for objects up to 30 mm diameter (20 μm focus, 30 watts);40 μm for objects up to 60 mm diameter (20 μm focus, 30 watts);At larger diameters, achievable spatial resolution will be ≤ (Field of View)/1500 (75 watts).

CT Scan Times -48 seconds (360 views);96 seconds (720 views);192 seconds (1440 views).

Manipulator Specifications -The slice plane orientation is horizontal (X,Y). The turntable rotation axis orientation is vertical.The slice positioning linear axis orientation is vertical (Z). The part manipulator is computercontrolled for CT imaging or operator controlled for optimal location of CT slice planes using theFluoroscopy mode. The 75 mm diameter turntable has four M4 tapped holes on 68 mm O forfixture mounting;Horizontal travel (X axis, magnification) 400 mm;Horizontal travel (Y axis, centering) 100 mm;Vertical travel (Z axis) 200 mm;Turntable continuous rotation in either direction;Absolute accuracy 5 degree/s;Repeatability 5 degree/s;Maximum vertical speed 2 mm/sec;Maximum rotation speed 24 degree/sec.
