Abstract (en)

[origin: WO9919716A1] CT (120) baggage (112) inspection with a throughput on order of 700 bags (112) per hour is achieved by excluding unrelated data from reconstruction. By using a threshold, calibration "air scans" can be performed with objects such as the system conveyor (110) in the field of view. The scanner identifies object shape to better detect sheet explosives. The system compensated for dark currents and temperature dependent current offsets.
