Abstract: Described herein is a high-energy x-ray imaging system including a stationary gantry, a conveyor assembly configured to convey an object to be imaged through the gantry, a plurality of linear accelerators, a detector array, and a control system. The linear accelerators are arranged in an array within the gantry and are configured to generate high-energy x-ray fan beams to be transmitted through the object. The detector array is positioned opposite the linear accelerators and is configured to collect the high-energy x-ray fan beams transmitted through the object. The control system is configured to energize the linear accelerators according to a predetermined control sequence to generate the high-energy x-ray fan beams, and construct a 3-D image of the object based on data received from the detector array and representative of the high-energy x-ray fan beams transmitted through the object.

Abstract: A detection device for detecting the presence of a substance of interest in a sample is described. The device can include a data store comprising executable instructions for at least one convolutional neural network, CNN, configured to process images: and a processor coupled to the data store and configured to execute the instructions to operate the at least one CNN. The detection device can be configured to: obtain spectrometry data, operate a first one of the CNNs to process the spectrometry data to obtain a first CNN output; apply a mask to the spectrometry data to obtain masked data; operate a second one of the CNNs to process the masked data to obtain a second CNN output; and determine if the substance of interest is present in the sample based on both the first CNN output and the second CNN output.
