FIELD: medicine.SUBSTANCE: invention relates to mammography. Method of providing mammography information on the region of interest, wherein the region of interest has a structure of tissue, wherein the method includes the following stages: a) obtaining a first image data with the first imaging parameters; the first imaging parameters are adapted to the first double-mode radiation spectrum energy, and the first imaging is performed with low-dose x-ray radiation pre-scan; b) obtaining a second image data with the second imaging parameters; the second imaging parameters are adapted to the second double-mode radiation spectrum energy, and the second imaging is performed with a higher dose x-ray radiation than the first imaging, wherein the second Imaging represents mammography scanning, the first radiation dose is used during the first obtaining an image, and the second radiation dose-during the second production, wherein the first dose makes, at least , less than 10% of a second dose; c) carrying out based on double energy decomposition of the main material based on the first and second image data to generate image data which is the main material; d) obtaining information on the tissue structure density in the region of interest from image data of decomposed main material; and providing information on the density to the user.EFFECT: technical result is evaluation of mammary gland density with improved accuracy.11 cl, 11 dwg |
