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 tube are tested. Unfolded spectra are compared with theoretical extracted from IPEM-78 catalogue. A 2 ¿ error criterion is applied to assess the minimum variations in tested parameters that permits distinguishing between close spectra. © 2010 Elsevier Ltd.
