摘要： A method of and a system for automatic object display of volumetric CT data for fast on-screen threat resolution are disclosed, wherein the CT data includes a CT image in a single energy CT scanner, or a CT image and a Z image in a multi-energy CT scanner, and a label image defining each object as a plurality of voxels of the volumetric CT data. The method comprises generating volumetric CT image data corresponding to a scanned bag; performing automatic threat detection to generate a label image; processing the volumetric CT data and the label image to obtain visualization parameters for each object; automatically generating display images for each object using corresponding visualization parameters; and displaying the generated display images for on-screen threat resolution.

摘要： Potential threat items may be concealed inside objects, such as portable electronic devices, that are subject to imaging for example, at a security checkpoint. Data from an imaged object can be compared to pre-determined object data to determine a class for the imaged object. Further, an object can be identified inside a container (e.g., a laptop inside luggage). One-dimensional Eigen projections can be used to partition the imaged object into partitions, and feature vectors from the partitions and the object image data can be used to generate layout feature vectors. One or more layout feature vectors can be compared to training data for threat versus non-threat-containing items from the imaged object's class to determine if the imaged object contains a potential threat item.

摘要： An apparatus for detecting X-rays and converting the detected X-ray intensities into digital signals is disclosed. The apparatus places Analog to Digital Conversion (ADC) chips directly under a scintillator array along the X-ray beam direction and uses a shield that is placed between a photodiode substrate and an Analog to Digital Conversion (ADC) chip to block X-rays from directly reaching the dies of the ADC chips, which are sensitive to X-rays. Also an X-ray CT system utilizing the disclosed apparatus for detecting X-rays is provided.
