Embodiment Construction

[0071] figure 1 A flowchart of an embodiment of a method for determining a two-dimensional mammography data set G_x, G_x' is shown. The optional steps of the method are shown here with dashed lines.

[0072] In addition, Table A shows the relevant pseudo code of this embodiment.

[0073]

[0074] The first step of the illustrated embodiment is to receive the three-dimensional mammography data set x of the REC examination area by means of the interface DS.1. This step corresponds to code line A.1. The three-dimensional mammography data set x here is a digital breast tomosynthesis. The three-dimensional mammography data set x includes voxels arranged in a three-dimensional grid, wherein the extension of the three-dimensional mammography data set x in the first direction corresponds to L 1 Voxel, the extension in the second direction corresponds to L 2 Voxel, where the second direction is orthogonal to the first direction, and the extension in the third direction corresponds to L 3 ...

Abstract

The invention relates to a method for determining a two-dimensional mammography data set. The method includes receiving a three-dimensional mammography data record of the examination region by means of an interface. The method further comprises first determining the two-dimensional mammography dataset of the examination region by means of the computing unit by applying a trained generator function to the three-dimensional mammography dataset, wherein the trained generator function is based on the trained GA network. The inventors have realized that by means of this method it is possible to efficiently generate two-dimensional mammography data sets which are visually similar to real two-dimensional mammography data sets and which can therefore be diagnosed using standardized methods.

Description

Technical field [0001] The invention relates to a method for determining a two-dimensional mammography data set and a determination system. Background technique [0002] Digital breast tomosynthesis (DBT) is a promising development of two-dimensional mammography as the current diagnostic standard method. DBT provides three-dimensional information about the anatomical structure of the breast, which reduces the number of false positives of two-dimensional mammography due to the superimposition of fibroid tissue. But on the other hand, diagnosis based on digital breast tomosynthesis increases the workload of the doctor who makes the diagnosis because multiple layers of records must be checked. [0003] In order to perform diagnosis more efficiently, especially the search for lesions, it is advantageous to provide two-dimensional mammography in addition to digital breast tomography. Although two-dimensional mammography can be provided by separate imaging with ionizing radiation, this...
