Summary:The invention provides a mammary X-ray photography method, comprising the following steps: shooting a mammary X-ray image under the conditions of 25-27kV and 8-11 MAS and recording the image on an IP plate; sending an image signal into a computer; fixing a tuning curve into a constant and setting a rotation center within 0.3-2.6, preferably 1.0-1.4 so as to clearly display an induction zone on a screen; adjusting rotation quantity so as to regulate the contrast ratio of the image into -4-4, and increasing and decreasing the quantity with 0.1 unit as a base number so as to form gradually intensive black-and-white contrast of the image; and adjusting the amount of movement so as to regulate the density of the whole image into -1.44-1.44, and increasing and decreasing the amount with 0.01 unit as a base number to obtain density and brightness optimization of the whole image. In the method, X-ray photography dosage is only about 25% of the conventional dosage, thus reducing the damage of X-ray on patients; and th
