Counting digital X-ray detector and method for taking a series of X-ray images

摘要

A counting digital X-ray detector for taking X-ray images of an object penetrated by X-ray radiation may include at least one detector module having an X-ray converter for converting X-ray radiation into an electrical signal and a matrix having a large number of counting pixel elements, wherein each counting pixel element has a signal input, a conversion device for converting the electrical signal into a count signal and a first digital storage unit for storing the count signal, wherein exactly one second digital storage unit is allocated to each first storage unit, and this is designed to form a copy of the first storage unit at the moment of transfer by way of a transfer process, and wherein the X-ray detector is designed in such a way that the transfer process can be carried out simultaneously for the large number of pixel elements.
