    • A tomography method for generating a computed tomography (CT) image, including generating a first tomography image based on first raw data corresponding to a received X-ray comprising acquired photons; determining second raw data by generating a second tomography image having an increased resolution in comparison with the first tomography image and performing forward projection on the second tomography image; determining third raw data based on a first parameter, the first raw data, and the second raw data; and generating a third tomography image based on the third raw data, wherein the determining of the third raw data may be based on information about a distribution of the acquired photons, the information being included in at least one from among the first raw data and the second raw data.
    • 用于生成计算机断层摄影(CT)图像的断层摄影方法,包括:基于与接收到的包括获取的光子的X射线对应的第一原始数据生成第一断层摄影图像; 通过生成与第一断层图像相比具有增加的分辨率的第二断层图像并且对第二断层图像执行前向投影来确定第二原始数据; 基于第一参数,第一原始数据和第二原始数据确定第三原始数据; 以及基于所述第三原始数据生成第三断层图像,其中所述第三原始数据的确定可以基于关于所述获取的光子的分布的信息,所述信息被包括在所述第一原始数据和所述第二原始数据中的至少一个中, 第二个原始数据。
