Conclusion

This experiment demonstrates that there is evident relationship between PA projection and breast dose. Equivalent dose (H_T) to the breast can be reduced by 93% by performing PA full spine protocol acquisition having the lowest dose without loss of image quality.

In conclusion, it is evident that, this study has shown that the use of the PA projection with gonad covers and manual setting of exhibition parameters, allows to reduce radiation dose to the breast, while allowing a good diagnostic image. Use of lead cover, in combination AEC, produces an increase in total DAP. More research, into use the AEC and cover gonads is still necessary before obtaining a definitive answer to effect on the DAP and related non-stochastic effects.
