摘要: 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.

摘要: 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.

摘要: A method for scanning a stream of objects includes conveying the stream of objects through a scanning system using a conveyor, marking a leading edge position of an object within the stream of objects with respect to a first known distance between a sensor and a start of a scan range, and recording data associated with the object when the leading edge position reaches the start of the scan range. The method also includes marking a trailing edge position of the object with respect to a second known distance between the sensor and an end of the scan range, halting recording of the data when the trailing edge reaches the end of the scan range, and generating a three-dimensional image of the object based on the recorded data.
