Application of the Monte Carlo codes PENELOPE and MCNP5 to unfold X-ray spectra in the diagnostic energy range

Gallardo Bermell, Sergio; Querol Vives, Andrea; Pozuelo Navarro, Fausto; Verdú Martín, Gumersindo Jesús; Ródenas Diago, José (Elsevier, 2014-02)

Obtaining primary X-ray spectra is a complex task mainly due to the high fluence of X-rays. In order to avoid the pile up effect in the detector, an indirect method based on the Compton scattering interactions in a low ...
Application of the MTSVD and Tikhonov unfolding methods for reconstruction of primary X-ray spectra of mammography equipments with silicon detector

Querol Vives, Andrea; Gallardo Bermell, Sergio; Ródenas Diago, José; Verdú Martín, Gumersindo Jesús (American Nuclear Society, 2011)

[EN] Quality control of mammography units is necessary to reduce the dose imparted to women as much as possible. Accurate characterization of the primary X-ray spectra is very useful for this purpose. Obtaining primary ...
Parametric study of the X-ray primary spectra obtained with the MTSVD unfolding method

Querol Vives, Andrea; Gallardo Bermell, Sergio; Ródenas Diago, José; Verdú Martín, Gumersindo Jesús (Elsevier, 2011-08)

The Modified Truncated Singular Value Decomposition (MTSVD) unfolding method is applied to obtain primary spectra for X-ray tubes in radiodiagnostic. Three parameters - voltage, anode angle and filter thickness- of the ...
