Abstract:
1. A method to display a predetermined volume segment of an examination subject by tomosynthesis, comprising the steps of: operating a tomosynthesis apparatus, comprising an x-ray source and a radiation detector, to implement a radioscopy test by generating x-rays with a defined radiation dose from said x-ray source, said x-rays traversing a predetermined volume segment of a breast of an examination subject and striking said radiation detector with an intensity that is detected by said radiation detector; in a processor, automatically calculating a first radiation dose necessary for x-rays emitted by said x-ray source to be able to produce a two-dimensional diagnostic mammogram of the examination subject, dependent on the defined radiation dose and the detected intensity; in said processor, automatically calculating a second radiation dose for x-rays generated by said x-ray source to implement a tomosynthesis procedure, dependent on said defined radiation dose and the detected intensity, said second radiation dose being substantially lower than said first radiation dose; and operating said tomosynthesis apparatus to implement said tomosynthesis procedure by irradiating said predetermined volume segment of the breast with x-rays generated by said x-ray source from a plurality of different projection directions with x-rays being generated at each of said projection directions with said second radiation dose, said x-rays generated with said second radiation dose at each of said projection directions striking said detector after traversing the predetermined volume segment.
