1. An imaging system, comprising: a radiation source (110) that emits radiation that crosses the examination area； a detector (116) that detects radiation that crosses the study area and the subject located in this area and generates a signal characterizing the energy of the detected radiation ； a data selector (122) that discriminates the signal with respect to energy based on the settings related to the energy spectra corresponding to the first and second spectral characteristics ontrastnogo substance administered into a subject, wherein the contrast agent has a first attenuation spectral characteristic when attached to a target and a second different spectral characteristic in a state of non-alignment to the target； reconstruction block (134), which reconstructs the signal based on the first and second spectral characteristics and generates volumetric image data characterizing the target. 2. The imaging system according to claim 1, in which the contrast medium contains at least two materials having a K-absorption edge, and the energy spectra of the emitted and detected radiation are based on two materials having a K-absorption edge. The imaging system of claim 1, wherein the contrast agent comprises a structure with at least two materials with different spectral characteristics, and one of the at least two materials is separated from the structure when the structure is attached to the target, due to whereby the spectral characteristics of the structure change from the aforementioned first spectral characteristic to a second distinguishing1.
