Title:
画像アーチファクトを減少させる方法およびシステム
Document Type and Number:
Japanese Patent JP4542227
Kind Code:
B2
Abstract:
The present invention, in one form, includes a digital x-ray imaging system which, in one embodiment, collects projection data from a plurality of views and reduces artifacts caused by detector residual signals. More specifically and in one embodiment, volumetric images are generated by collecting projection data for a plurality of views. During inactive periods between the collection of projection data for adjacent views, the x-ray emission is stopped and each detector pixel is simultaneously energized to reduce a residual signal of each pixel. As a result, projection data for a subsequent view is not biased by the residual signal from a previous view.
