Objective To test a digital X-ray imaging device that captures X-ray photons directly on the basis of a pixel detector, which can read electrons in conjunction with photon counting. Method The chip consists of a matrix of 256 × 256 pixels and a 55μm pixel spacing. A one-piece image of 11.2 cm x 7 cm was obtained by a continuous displacement method. With new
