| description | The X-ray fluorescence (XRF) spectrum of specific elements
can be utilized in energy calibration, energy resolution
measurement, and analysis of energy response functions for
photon-counting detectors (PCDs). The applications can be beneficial
for PCD threshold accuracy, performance verification, and optimizing
image quality. In previous literature, the experimental
configuration for the XRF spectrum typically employed a vertical
configuration to avoid the influence of the primary X-ray
beam. However, such an experimental configuration is constrained by
the fixed position of the X-ray source and detector in the computed
tomography (CT) system. Hence, the purpose of this study is to
investigate a horizontal configuration for XRF measurements and
compare the differences in XRF spectrum with vertical
configuration. The results indicate that the spectral
characteristics of the horizontal and vertical configurations are
similar, suggesting that the horizontal configuration could be
applied for energy calibration and spectral analysis in PCD-CT
systems. |
