Data acquisition system for radiographic imaging

Claim 1

A continuous data acquisition system for radiographic imaging, without interrupting acquisition activity the acquisition system comprising: at least two memory means for storing radiographic data from a radiation detector wherein each of the memory means having a plurality of addressable memory locations and each of the memory means are such that said locations of the memory means correspond to spatial locations in the radiation detector; logic control means for sensing radiographic data transmitted by the radiation detector, for selecting one of said memory means for storage of said data, for transferring data to the selected memory means, and for switching from one memory means to another memory means according to a predefined schedule and according to memory capacity level, said logic control means further comprising a logic device which receives data and increments the contents of locations in a memory means in response to such data; and interface control means for reading data from one or the other memory means when such memory means is not actively acquiring data such that data can be acquired continuously by the system.
