Zusammenfassung:To improve image quality.SOLUTION: A reconstruction device includes correction means, selection means, and reconstruction means. The correction means obtains multiple second sinogram data on the basis of multiple first sinogram data. Selection means compares the first sinogram data and the second sinogram data, and selects the first sinogram data with high similarity to obtain third sinogram data. The reconstruction means reconstructs an image on the basis of the third sinogram data.SELECTED DRAWING: Figure 1 【課題】画質を向上させること。【解決手段】実施形態に係る再構成装置は、補正手段と、選択手段と、再構成手段とを備える。補正手段は、複数の第１のサイノグラムデータに基づいて複数の第２のサイノグラムデータを求める。選択手段は、前記第１のサイノグラムデータと前記第２のサイノグラムデータを比較し、類似性の高い前記第１のサイノグラムデータを選択することにより第３のサイノグラムデータを求める。再構成手段は、前記第３のサイノグラムデータに基づいて、画像を再構成する。【選択図】図１
