Abstract: A computed tomography (CT) apparatus includes a reconstruction unit which reconstructs a first CT image corresponding to a field of view (FOV) by using a first sinogram acquired by a CT scan of an object; and a correction unit which acquires a second sinogram by performing forward projection on the first CT image and acquires a second CT image by using the second sinogram and a third sinogram representing a portion of the object that is not included in the FOV. Thus, the CT apparatus reduces generation of image errors to thereby provide a high-quality reconstructed CT image.

Abstract translation: 计算机断层摄影（CT）装置包括重建单元，其通过使用通过对象的CT扫描获取的第一正弦图来重建与视场对应的第一CT图像（FOV）; 以及校正单元，其通过在第一CT图像上执行向前投影来获取第二正弦图，并且通过使用第二正弦图获取第二CT图像，以及表示不包括在FOV中的对象的一部分的第三正弦图。 因此，CT装置减少图像误差的产生，从而提供高质量的重建CT图像。
