Breast cancer is a multiple disease that endangers the lives of women. The standardized death rate in Europe and the United States has reached 100 thousand in 100000, and China has reached 3 out of 100000. The incidence rate has an increasing trend. Early diagnosis and early treatment are effective, with a survival rate of up to 97%. Early detection of breast cancer can be performed using soft X-ray photography. It has been widely used in clinics abroad. This article deals with the technical special sound of soft X-gland cameras and the necessity of research and production.
