Abstract: Systems and methods for non-intrusive analysis and display of internal features of wooden objects are provided. In embodiments of the system, a log is passed through a CT scanner in one continuous motion. One or more x-ray sources revolve around the log generating x-ray beams that traverse contiguous cross-sections of the log. An array of x-ray detectors detects x-rays that traverse the log for variations in the attenuation of rays. The detected attenuation is converted into spiral scan data that corresponds to projections in different contiguous cross-sections traversed by the x-rays. An image processor reconstructs spiral scan data into two dimensional cross-sectional images of the log by processing and formatting scan data using a planar reconstruction technique. The system renders three-dimensional views based on two-dimensional images.

Abstract: A readily relocatable X-ray imaging system for inspecting the contents of vehicles and containers, and a method for using the same. In a preferred embodiment, the system is relatively small in size, and is used for inspecting containers and passenger vehicles, such as cars, SUVs, and small trucks, at a variety of sites. The X-ray inspection system includes a substantially rectangular frame having an X-ray imaging system disposed thereon. The frame is detachably connected to a conveyor mechanism having a minimal height, which allows drivers and passengers of vehicles to readily step off of and onto the conveyor mechanism without the aid of steps, railings, and the like. In a preferred configuration, the conveyor mechanism includes two detachable sections comprising a plurality of rollers, or other transport mechanism, having a radio-transparent plate or belt resting thereon for transporting a vehicle or container through the inspection area under the X-ray frame.
