摘要: The invention relates to characterisation of plague. A method is for the characterization plaques (LP, FP, CP) in a region interest inside an examination subject (10) by way plurality image data sets (BDLE, BDHE). sets(BDLE, BDHE) have been reconstructed from projection sets, which acquired via CT device using different X-ray energy spectra. includes: acquiring BDHE), include pixels. Spectral parameter values (SP1, SP2) are on pixel basis at least two Character (CP) then characterize spectral SP2). An analysis unit (25) and computed tomography system (1) also disclosed.
