Abstract:
The results of the tests of multybeam X-ray tube for 3D digital mammography are presented. Mammography is currently the only way to diagnose breast cancer in its early stages. In mammography, there are restrictions on patients with dense structure of the mammary glands and diagnosed with «fibrocystic breast disease» associated with the complexity of the interpretation of mammographic images by physicians as overlapping tissue (including outside the study area) creates significant visual disturbances. In this case, the using of com-puter tomography allows significantly improve the quality of diagnosis. Digital breast tomosynthesis enables obtaining three-dimensional images of the breast as separate sections on which no image of the objects from the upper or lower layers that complicate diagnosis in conventional X-ray mammography. Phantom of the breast with inclusions of microcalcinates specsfications, the nylon fibers and simula-tors of cancer was selected as the scan object. 15 images of it were obtained by scanning in the intersecting directions, then tomosyn-thesis was provided with the 2D object cuts. The apparent sizes in the image cut were 0.165 mm for microcalcinates, 0.53 mm for nylon fibers and 0.9 mm for simulators of cancer. It is shown that the sharpness of the image with fixed X-ray sources may be better than for the X-ray source moving around the scan object.
