| Abstract: | The summarized imprecision of X ray mammography is conducted by analyzing the different factors,size of the X ray tube focus spot,dynamical imprecision and screen film imprecision which affect the sharpness of imagine in X ray mammography.In order to get the minimum value of the visually recognized summarized imprecision,the optimized geometrical zooming factor and the relationship between effective focus spot size and screen film imprecision is acquired. |
