    Abstract: In an image processing method and an image processing apparatus, projection and back-projection methods are provided. The projection and back-projection methods include the steps of: projecting the center of a detector cell included in a detection unit on a common axis; mapping a boundary of pixels of a pixel grid with the common axis; projecting the center of the detector cell included in the detection unit on a preset common axis; and determining a pixel value based on the step of mapping the boundary of the pixel on the preset common axis.

    Abstract translation: 在图像处理方法和图像处理装置中,提供投影和反投影方法。 投影和反投影方法包括以下步骤:将包括在检测单元中的检测器单元的中心投影在公共轴上; 将像素网格的像素的边界与公共轴映射; 将包括在检测单元中的检测器单元的中心投影在预设公共轴上; 以及基于在所述预设公共轴上映射所述像素的边界的步骤来确定像素值。
