Abstract:
1. A system comprising: a first x-ray source configured to generate x-rays having energies in a first range; a first imaging x-ray detector configured to detect the x-rays in the first range and to generate resulting first projection image data of a target; a second x-ray source configured to generate x-rays having energies in a second range; a second imaging x-ray detector configured to detect the x-rays in the second range and to generate resulting second projection image data of the target, the target disposed at an intersection of a first axis between the first x-ray source and the first imaging x-ray detector and a second axis between the second x-ray source and the second imaging x-ray detector; a first logic configured to convert the first projection image data to a scale compatible with the second projection image data; and a second logic configured to generate a computerized tomography image using the converted first projection image data and the second projection image data.
