摘要： The present disclosure relates to detection systems and methods. One illustrative detection system may include a distributed radiation source having a plurality of radiation source focus points, which irradiate an object under detection, wherein the plurality of radiation source focus points are divided into a certain number of groups, and a primary collimator that limits rays of each of the radiation source focus points such that the rays emit into an XRD detection device. An XRD detection device may include a plurality of XRD detectors that are divided into the same number of groups as the radiation source focus points, wherein XRD detectors in a same group are arranged to be separated by XRD detectors in other groups, and rays of each of the radiation source focus points are received by XRD detectors having the same group number as the group number of the radiation source focus point.

摘要： Systems and methods for liquid detection are disclosed. An illustrative method for liquid detection herein may include implementing CT imaging and XRD imaging on one or more liquid planes of liquid contained in a container at once by rotating the container so that X-rays from a same radiation source scan a whole area of each of the one or more liquid planes, and generating a substance identification result for the liquid contained in the container based on a CT image and a XRD image, wherein the CT imaging and the XRD imaging are implemented on a same liquid plane or different liquid planes. Consistent with various aspects and features, implementations may identify substances contained in the liquid more quickly and accurately.

摘要： The present disclosure relates to multi-modality detection systems and methods. One illustrative multi-modality detection system may include a distributed radiation source configured to irradiate an object under detection, a primary collimator configured to separate rays of the distributed radiation source into two parts, wherein one part is for CT detection and the other part is for XRD detection, a CT detection device configured to perform a CT detection to acquire a CT image of the object under detection, and an XRD detection device configured to perform an XRD detection to acquire an XRD image of the object under detection, wherein the CT detection and the XRD detection are performed simultaneously.
