    • An X-ray CT apparatus has a setting unit, a generating unit, a calculation unit, and a determination unit. The setting unit sets a required width of a group of X-ray detection elements in a row direction, which is relatively insusceptible to an influence of a cone angle of a cone-beam X-ray. The generating unit generates accumulation data by accumulating first projection data, based on first X-ray detection elements within the required width included in the group, with same channel in the row direction in preference to second projection data based on second X-ray detection elements outside the required width included in the group. The calculation unit obtains a motion amount for each heartbeat phase based on the accumulation data. The determination unit determines a specific heartbeat phase based on the motion amount for the each heartbeat phase.
    • X射线CT装置具有设定部,生成部,计算部以及判定部。 设置单元设置一组X射线检测元件在行方向上的所需宽度,这对于锥形束X射线的锥角的影响是相对不易察觉的。 生成单元优先于基于第二X射线检测元件的第二投影数据,通过累积第一投影数据,基于组中包含的所需宽度内的第一X射线检测元件,在行方向上具有相同的通道, 在组中包含的所需宽度之外。 计算单元基于积累数据获得每个心跳相位的运动量。 确定单元基于每个心跳阶段的运动量确定特定的心跳相位。
