Title: Mech. Gantry System For Nondestructive Testing Of Huge Objects / Lieferung Drehbares Portalsystystem description: Delivery Of A Portal Rotatable Gantry-type System Prepared For The Integration Of A 9 Mev Linear Accelerator And A 4 M Long X-ray Detector For Computed Tomography Of Large Objects (e.g. Complete Cars) In The Field Of Non-destructive Testing. This Gantry Is Intended To Scan Objects With Outer Dimensions Of A 20-foot Sea Freight Container (1teu). The Mechnical Design And The Corresponding System Controls Must Support Two Distinct Ct Scan Procedures. The Sfb Scan Procedure Is Designed Such That The Object Is Moved In X-direction Through The Gantry Continuously At A Constant Velocity While The Gantry Remains Stationary At A Fixed Rotation Angle. After The Object Has Successfully Passed Through, The Gantry Is Rotated By One Angular Step, And The Object Is Moved Through The Gantry Again In Reversed Direction. The Sinogram Scan Mode Involves The Continous Rotation At A Constant Angular Velocity Of The Gantry While The Object Remains Stationary.
