【Abstract】 Radiation of the point radioactive source and non-point radioactive source are discussed in this paper. For simplicity, quadratic γ-ray will be researched elsewhere. Wediscuss radiation of the point radioactive source, the line- radioactive source and the bar-radioactive source. We wish to help the designing of CT and to make optimization of CT system.更多还原
