BREAST DENSITY ASSESSMENT |
摘要 |
<p>The present invention relates to mammography. To provide breast density assessment with improved accuracy in the results, a method (100) is proposed for providing mammography information about an object of interest, the region of interest comprising a tissue structure, with the following steps: a) acquiring (110) first image data (112) with first image acquisition parameters (114), wherein the first image parameters are adapted to a first radiation spectrum of a dual energy mode; and wherein the first image acquisition is performed with a low X-ray dosage of a pre-scan; b) acquiring (116) second image data (118) with second image acquisition parameters (120), wherein the second image parameters are adapted to a second radiation spectrum of the dual energy mode, and wherein the second image acquisition is performed with a higher X-ray dosage than the first image acquisition, and wherein the second image acquisition is a Mammography scan; c) performing (122) a dual energy basis material decomposition (124) based on the first and second image data to generate decomposed basis material image data (126); and d) deriving (128) a density information (130) of the tissue structure of the region of interest from the decomposed basis material image data; and providing (132) the density information to a user.</p> |
