Industrial CT (computed tomography) scanning is a process which interlaces 2D x-ray images to produce 3D representations of a component both internal and external. Since x-rays are used, a delicate and fragile part can be scanned in a free state environment without the need for fixtures. Measurement can be performed on the CT dataset.
CT scanning allows you to inspect, and measure internal components of an assembly to check feature detail or verify the piece geometry. Jesse Garant & Associates (www.jgarantmc.com) is a metrology laboratory offering services for industrial ct scanning (3D xray) a NDT.
