Patent number: 9888897Abstract: Methods of imaging a breast comprising acquiring a sequence of image data sets having differing exposure parameters; and combining the image data sets into a mammography image having greater dynamic range than the dynamic range of any single component image data set. Disclosed methods may further comprise determining an exposure parameter of one or more component image data sets prior to acquiring the sequence of image data sets. The step of determining an exposure parameter of one or more component image data sets may comprise determining exposure duration or an exposure irradiation level. Also disclosed are mammography apparatus and systems to obtain images according to the disclosed methods.Type: GrantFiled: December 1, 2015Date of Patent: February 13, 2018Assignee: Dexela LimitedInventors: Edward Bullard, Spencer Gunn, James Brodrick, Hamdan Amin
