This information makes the treatment planning for heavy-ion radiotherapy more precise. We have started a feasibility study on the dual-energy x-ray CT by using synchrotron radiation. We developed a linear scanning CT system(1D-CT) in order to evaluate what precision in the measurement was achieved. Comparison fo measured electron densities with the theoretical values proved that these values were in afreement in 0.9 % on average. We haave developed a 2D-CT system with a two-dimensional scintillator array to take images in a short time. At present, it has been proved that the electron density is measured in the precision of about 1 %.\n  Effectove atomic numbers are obtained as well from the dual-energy x-ray CT. They present a different feature of an object, and the contrasts in the images differ from that in a conventional CT image. The feature of the images may help distinguish more clearly tissues or organs with aid of difference contrast from the conventional CT images.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"International Symposium on
