X-RAY CT APPARATUS

摘要

An X-ray CT apparatus comprising: a scanner unit for rotating one or more X-ray sources for applying X-ray beams having different energy spectra to a subject and detectors opposed to the X-ray sources and adapted for detecting transmitted X-ray data on the subject around the subject while applying X-rays, re-constructing means for reconstructing a tomogram of the subject by acquiring transmitted X-ray data on the subject including the two or more different energy spectra by using the scanner, and display means for displaying the re-constructed tomogram; the X-ray CT apparatus further comprising input means for inputting information on an identification tissue of the subject to be identified and a separate tissue to be separated from the identification tissue from the tomogram and imaging condition determining means for determining the imaging condition for identifying the identification tissue from the tomogram. With this, an optimum imaging condition of a multi-energy X-ray CT apparatus can be determined.
