FIELD: medicine.
SUBSTANCE: invention relates to field of medicine. In method realisation mammograms at two different energies of irradiation are obtained. Standard with known distributions of density, thickness and effective atomic number is placed neat mammary gland. Coefficients of connection of atomic number with difference and ratio of logarithms of number of photons, which have passed through mammary gland without interaction at two different energies of irradiation are determined and used to visualise its distribution in mammary gland.
EFFECT: method makes it possible to increase reliability of identification of microcalcinates at early stage of their formation due to combination of dividing and subtracting mammography, ensuring suppression of density variation and isolation of only variation of effective atomic number.
