    • According to one embodiment, an apparatus includes a reconstructing unit, a first control unit, a detecting unit, a generating unit, and a second control unit. The first control unit controls the reconstructing unit to reconstruct first images based on projection data collected in first periods. The detecting unit detects second periods which belong to pulsation cycles different from one another and in which an organ to be imaged is in the substantially same form, based on the first images. The generating unit generates data for reconstruction including projection data for the required angle range by combining projection data collected in third periods close to the second periods. The second control unit controls the reconstructing unit to reconstruct a second image based the data for reconstruction.
    • 根据一个实施例,一种装置包括重建单元,第一控制单元,检测单元,生成单元和第二控制单元。 第一控制单元基于在第一周期中收集的投影数据来控制重建单元重构第一图像。 检测单元基于第一图像检测属于彼此不同的脉动周期的第二周期,并且其中要成像的器官基本相同的形式。 生成单元通过组合在接近第二周期的第三周期中收集的投影数据来生成包括所需角度范围的投影数据的重建数据。 第二控制单元基于重建数据控制重建单元重建第二图像。
