Evaluation of a YAG:Ce scintillation crystal based CCD X-ray imaging detector with the Medipix2 detector

Original language description

Over the last decades the traditional photographic films used in radiology are being replaced by digital X-ray imaging sensors in many applications. The main advantages of these systems are their detection efficiency of image acquisition and the abilityto directly digitally transfer and enhance obtained images. In this paper we characterize and evaluate the X-ray imaging performance of a YAG:Ce single crystal scintillator. The scintillator converts X-rays into visible light that is collected by an optical camera. The camera uses a CCD sensor with the size of 36x24 mm2 and with 4050 x 2630 pixels of 9x9 ?m2 pitch, and is equipped with a macro objective. The semiconductor pixel detector Medipix2 was used for the evaluation of the imaging capabilities ofthis imaging system. The imaging capability is evaluated in terms of several basic characteristics: spatial resolution, edge response function, signal to noise ratio and contrast to noise ratio. A microfocus X-ray tube was used for high
