| 摘要 |
FIELD: physics.SUBSTANCE: invention relates to molecular imaging. The imaging system comprises a radiation source which crosses the investigated region, a detector for detecting radiation and generating a signal which characterises energy of the detected radiation, a data selector which performs signal discrimination according to energy based on energy spectrum-related settings which correspond to the first and second spectral characteristics of a contrast substance administered to a subject, and a unit for signal reconstruction based on the first and second spectral characteristics and generation of three-dimensional image data characterising a target. The contrast substance has a first spectral attenuation characteristic when bonded to a target and a second different spectral characteristic in a state without bonding to the target.EFFECT: use of the invention increases the amount of the obtained information on the composition of the tissue of a subject.10 cl, 14 dwg |
