The noise of a digital charge coupled device (CCD) detector increases with the readout speed, causing problems in a number of important applications, such as x‐ray fluoroscopy and micro‐CT. In this paper, we present an approach for the design of a dual‐CCD configuration to improve the average signal‐to‐noise ratio, and hence provide an inexpensive solution within the constraint of the current technology.
