We have designed a computational tool for generating X-ray photon spectra for a range ofapplications both in diagnostic radiology and mammography. As a library, we have adapted thespectral data based on the interpolating polynomials methods by Boone et al [5,6] as well as thecomputer data files given by Cranley et al [8]. The attenuated spectra for element or compoundmaterials can be calculated based on the mass-attenuation coefficients from NIST (National Instituteof Science and Technology), which were also incorporated as a database. Furthermore, a function thata user can generate any filter material by editing the NIST data has been implemented. Parametersrelated to the beam quality, such as mean photon energy, fluence, exposure, half-value layer (HVL),etc., are considered as important outputs. All of functions and database are integrated in a form ofgraphical user interface (GUI) by using Microsoft Visual C++TM. This self-developedspectrum-generating code can be usefully served to design X-ray sensors. In this study, we haveapplied the code to estimate quantum efficiency and charge collection efficiency in various detectormaterials
