Combination of contrast medium and mammography CT system with a prespecified energy range and method for generating tomographic mammography CT images by this combination
Combination of contrast medium and mammography CT system with a prespecified energy range and method for generating tomographic mammography CT images by this combination
A mammography CT system is disclosed which includes an X-ray generator; and a first radiator-detector system. A contrast medium, including an opacifying element including an absorption peak in a first energy range, is useable for tomographic imaging of a female breast of a patient. After filtering, the X-rays with a prespecified tube voltage that form at an anode, are configured to emit an X-ray spectrum having a second energy range, wherein the radiator-detector system is configured to acquire a plurality of circumferential projections around the breast. The first energy range is a part of the second energy range and the second energy range includes an upper limit of less than 70 keV and a lower limit of greater than 20 keV. A corresponding method for generating tomographic mammography CT images is also disclosed.
