摘要
A spectrum measurement and estimation method for tomographic reconstruction, beam hardening correction, dual-energy CT and system diagnosis, etc., comprises determining the spectra for combinations of source acceleration voltage, pre-filters and/or detectors and after measuring the transmission values of several pre-filters, calculating corrected spectra for the combinations of the source acceleration voltage, pre-filters and/or detectors.
