DEVICE AND METHOD FOR IMAGE RECONSTRUCTION AT DIFFERENT X-RAY ENERGIES, AND DEVICE AND METHOD FOR X-RAY THREE-DIMENSIONAL MEASUREMENT

摘要

Provided are a device and method for image reconstruction at different X-ray energies, whereby image reconstruction can be accomplished with higher accuracy. This device for image reconstruction at different X-ray energies includes: an X-ray source (1) for irradiating an imaging specimen (2) with X-rays; an energy dispersive detector (4) for detecting characteristic X-rays produced from the imaging specimen (2); a signal processing means for quantifying of characteristic X-ray peaks detected by the detector (4); and an image reconstruction means for reconstructing images on the basis of signals from the signal processing means.
