Response functions of Si(Li), SDD and CdTe detectors for mammographic x-ray spectroscopy
چکیده انگلیسی

In this work, the energy response functions of Si(Li), SDD and CdTe detectors were studied in the mammographic energy range through Monte Carlo simulation. The code was modified to take into account carrier transport effects and the finite detector energy resolution. The results obtained show that all detectors exhibit good energy response at low energies. The most important corrections for each detector were discussed, and the corrected mammographic x-ray spectra obtained with each one were compared. Results showed that all detectors provided similar corrected spectra, and, therefore, they could be used to accurate mammographic x-ray spectroscopy. Nevertheless, the SDD is particularly suitable for clinic mammographic x-ray spectroscopy due to the easier correction procedure and portability.


► The Si(Li), SDD and CdTe detectors were applied for mammographic x-ray spectroscopy.
► The detector response functions were studied using Monte Carlo simulation.
► The efficiency is the most important correction for the Si(Li) and SDD.
► The escape of fluorescents x-rays is a relevant correction for the CdTe.
► The use of SDD is advantageous for clinic mammographic x-ray spectroscopy.
