 note = {医用画像診断装置で撮影される画像において画質評価は重要な課題の1つである。医用画像の視覚特性の影響も考慮した心理評価手法の一つにC-Dダイアグラムがあるが，全ての撮影装置に対して評価用のBurgerファントムが準備されているわけではない。本論文ではすへての撮影装置を対象として，画像評価の物理特性であるMTFとウィナースペクトルのデータを元に仮想Burgerファントムを作成し，実際にX線診断装置にて撮影した画像データと比較してその妥当性を確認した。この仮想BurgerファントムがX線診断装置以外の画像診断装置に適用できるかどうかの評価は今後の重要な研究課題である。, Providing good image quality is considered to be one of the most important requirements for diagnostic imaging systems.
Methods for quantitatively evaluating image quality can be classified into physical methods and psychological methods. Although physical methods are generally well established, psychological methods （in which the influence of the visual characteristics of diagnostic images is also taken into consideration） often suffer from difficulties in quantification.
One psychological evaluation method involves the use of a C-D diagram with a Burger phantom. However, this method is not applicable to modalities other than X-ray systems and parameter setting is difficult.
In the present study, a virtual Burger phantom was constructed on a PC based on the MTF and Wiener spectrum data of the imaging system which is the physical characteristic of image evaluation.
The validity of this method was confirmed by comparing phantom image data against actually acquired image data using X-ray systems.
Further research will be needed to confirm that this virtual Burger phantom should be applicable to other modalities than X-ray system.},
