A method for scanning a stream of objects includes continuously acquiring raw data of the stream of objects using an X-ray system including a detector, determining a leading edge and a trailing edge of a first object of the stream of objects from the raw data acquired by the detector using a control system, processing acquired raw data of the first object based on the determined leading edge and the determined trailing edge using the control system, and reconstructing an image of the first object using at least the processed raw data. A system configured to perform the method is also disclosed.

Method and systems for scanning a stream of objects

A method for generating an image of an object using a scanning system includes performing a first portion of a scan in a first scanning mode to acquire a first dataset, receiving a halt command for a conveyor within the scanning system, decelerating the conveyor to a halt based on the halt command using a conveyor controller, and, when the object is present within an examination region after the conveyor has halted, performing a second portion of the scan in a second scanning mode to acquire a second dataset. The second scanning mode is different than the first scanning mode. The method also includes reconstructing the first dataset using a first reconstruction algorithm and reconstructing the second dataset using a second reconstruction algorithm. The second reconstruction algorithm is different than the first reconstruction algorithm. The image is generated using the first reconstructed dataset and the second reconstructed dataset.

Method and system for performing a scan of an object

An integrated, multi-sensor, Level 1 screening device is described, which system provides a next-generation Explosives Detection System (EDS) that enables high throughput, while drastically reducing false alarms. In exemplary embodiments, the present system comprises a non-rotational, Computed Tomography (CT) system and a non-translational, X-ray diffraction (XRD) system, both in an inline configuration.

Integrated multi-sensor systems for and methods of explosives detection

A system includes a generator configured to output at least one voltage level and an x-ray source configured to generate x-rays directed toward an object. The system includes a module coupled to the output of the generator and to an input of the x-ray source and configured to switch or assist in switching an output to the x-ray source between a first voltage level and a second voltage level.

System and method of fast switching for spectral imaging

An apparatus and method for scanning an object with a helical CT scanner, the method comprising: acquiring an amount of data corresponding to the object that is scanned by the CT scanner, wherein the amount of data is generated by an x-ray source that projects a fan beam of x-rays toward a detector array on an opposite side of a gantry of the CT scanner, the fan beam being generated at multiple x-ray source positions as the x-ray source is rotated about the object as the object passes through an opening in the gantry disposed about a conveyor for moving the object through the opening; monitoring a position of the conveyor as the object passes through the opening in the gantry; determining if the conveyor has been stationary for more than one rotation of the gantry and discarding redundant data after one rotation, optionally turning off the x-ray tube if the conveyor has been stationary for more than one gantry rotation, and if so preventing the conveyor from moving again until the tube is turned on and is stable, inputting the position of the conveyor at each x-ray source position into a reconstruction algorithm; and presenting an image of the object.

Apparatus and method for controlling start and stop operations of a computed tomography imaging system

A CT scanner acquires CT images at different energy levels and registers those images to provide a composite image that is substantially free of beam hardening artifacts and conspicuously provides atomic information of that imaged.

Image-based material decomposition

This invention relates to an x-ray based non-intrusive inspection apparatus. An x-ray source is mounted to a gantry and provides x-rays that transmit through an object. The x-rays have an included angle between first and second shadow lines. A circle of reconstruction is formed upon rotation of the gantry having a radius from a center axis of rotation of the gantry to a closest point on the first shadow line. The second shadow line passes through the center axis so that x-rays transmit through only half of the circle of reconstruction at any given moment. The entire volume within the circle of reconstruction is scanned due to rotation of the gantry. Such an assembly allows for the x-ray source to be placed closer to the center axis of rotation of the gantry without reducing the radius of the circle of reconstruction.
