A method includes acquiring a first dataset of projection measurements at a first energy spectrum and a second dataset of projection measurements at a second energy spectrum different from the first energy spectrum by switching between acquiring the first dataset for a set number of consecutive views at different projection angles at the first energy spectrum and acquiring the second dataset for the set number of consecutive views at different projection angles at the second energy spectrum. The set number of consecutive views is greater than one. The method includes supplementing both the first dataset with estimated projection measurements at the first energy spectrum and the second dataset with estimated projection measurements at the second energy spectrum to provide missing projection measurements at different projection angles not acquired during the imaging scan for the first dataset and the second dataset.

System and method for utilizing dual energy imaging in a computed tomography imaging system

An aperture comprises blocking members and for blocking X-rays. The blocking member has: an edge formed on an arc Alying on a circumference CFof a circle with radius raround a focal spot f in an XY-plane; an edge connected to one endpoint of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc Acontiguous to the arc A; and an edge connected to the other endpoint of the edge, the edge being formed to lie on the side of the X-ray detector with respect to an arc Acontiguous to the arc A.

Aperture, collimator, and X-ray tomographic imaging apparatus

The present invention provides a detector which suppress the crosstalk between detector cells while improving the acquisition efficiency of X-ray radiation. The detector includes a plurality of detector cells, arranged along a detection plane of X-ray, in which each detector cell has a scintillator unit made of a scintillator, and a photodiode for transduce the light incoming from the scintillator unit into electric signals. The scintillator units are partitioned each from another by the border, which has a groove extending in the channel and row directions. A scintillator is provided in some part of the border in the incident X-ray direction.
