Abstract
Objective To study the method of selecting appropriate exposure parameter of AOP mode and reducing the radiation dose effective with the control of image quality .Methods The unique mammary phantom was mammography in three different AOP mode(DOSE mode ,STD mode and CNT mode) and compared the radiation dose .150 sample was selected randomly .50 sample each mode ,and recorded the radiation dose .All image reach the diagnostic standard .The mean dose of the each mode were computed and compared with others .Results whatever the phantom mammography and the sample mammography ,the mean dose in DOSE mode was lowest ,higher in STD mode ,and highest in CNT mode .The number of fiber cords ,mass and calcification fit the standard of quality control .The image of sample aslo fit the diagnostic standard .Conclusion In daily work ,we can lower the dose choosing appropriate mode according to the thickness and density of mammary .DOSE mode prior ,STD mode advocate limit to CNT mode .关键词
