Rapid kV Switching 法による CT Dual Energy Scan の検討(1) : Monoenergetic Image の基礎的評価

概要

論文の詳細を見る
As for Dual Energy Scan by the Rapid kV Switching method (RKS method), there is no influence of movement in comparison with the conventional 2-scan method. Also, various processing of the high reliability that was not obtained when the post-reconstruction method is used, because it is using the pre-reconstruction method when dual processing is produced. There is a Monoenergetic Image (MEI) as one of those processings. It is one of the simulated images that is made by using a single X-ray spectrum. To improve the accuracy of the CT-value by the thing that it decreases beam-hardening effect can. Also, it consists of one means clarifying the constitution substance of a photographic subject. Thereupon, we carried out a basic evalution, by using a phantom.
