Abstract

Pixelated Cadmium Zinc Telluride (CdZnTe) detectors were computationally modelled using a comprehensive framework that integrates Monte Carlo and Finite Element numerical methods. Realistic and accurate models were constructed for various detector thickness and pixel sizes. The detection efficiency was assessed after photon irradiation within a range of energies used in medical x-ray imaging applications such as mammography and computed tomography. The outcome of the computational experiments will assist in the determination of an optimum pixelated detector geometry for medical imaging applications.
