Displaying system for displaying digital breast tomosynthesis data

A displaying method for displaying DBT data, the displaying method comprising:

• providing first and second DBT volume images of the left breast of a woman and first and second DBT volume images of the right breast of the woman by an image providing unit, wherein the first DBT volume images correspond to at least one of a first image generation time and a first view and the second DBT volume images correspond to at least one of a second image generation time and a second view;
• providing for each DBT volume image a respective two-dimensional navigation image by a navigation image providing unit;
• providing for each DBT volume image a set of CAD markers by a CAD marker providing unit, wherein each CAD marker is associated with a set of two-dimensional locations on the respective two-dimensional navigation image and a set of three-dimensional locations in the respective DBT volume image;
• providing correlation scores being indicative of a likelihood that CAD markers of different DBT volume images of the same breast correspond to each other by a correlation score providing unit;
• facilitating a user indicating a two-dimensional location on a navigation image displayed on a display unit by a user interface, wherein this navigation image is regarded as being an activated navigation image and the DBT volume image, for which the activated navigation image has been provided, is regarded as being an activated DBT volume image of an activated breast;
• determining a CAD marker associated with the indicated two-dimensional location by a CAD marker determination unit, wherein the determined CAD marker is regarded as being an activated CAD marker, and determining another CAD marker of the other DBT volume image of the activated breast, which corresponds to the activated CAD marker, based on the provided correlation scores;
• determining a first slice position (z) defining a position of a slice of the activated DBT volume image, which includes a three-dimensional location of the activated CAD marker, and determining a second slice position (zc) defining a position of a slice of the other DBT volume image, which includes a three-dimensional location of the other CAD marker, by a slice determining unit;
• and
• controlling the display unit to display the slice of the activated DBT volume image at the determined first slice position (z) and the slice of the other DBT volume image at the determined second slice position (zc).

A computer-readable storage medium containing instructions for controlling a computer processor to display DBT data, the instructions comprising program code logic for performing a method comprising:

• providing first and second DBT volume images of the left breast of a woman and first and second DBT volume images of the right breast of the woman by an image providing unit, wherein the first DBT volume images correspond to at least one of a first image generation time and a first view and the second DBT volume images correspond to at least one of a second image generation time and a second view;
• providing for each DBT volume image a respective two-dimensional navigation image by a navigation image providing unit;
• providing for each DBT volume image a set of CAD markers by a CAD marker providing unit, wherein each CAD marker is associated with a set of two-dimensional locations on the respective two-dimensional navigation image and a set of three-dimensional locations in the respective DBT volume image;
• providing correlation scores being indicative of a likelihood that CAD markers of different DBT volume images of the same breast correspond to each other by a correlation score providing unit;
• facilitating a user indicating a two-dimensional location on a navigation image displayed on a display unit by a user interface, wherein this navigation image is regarded as being an activated navigation image and the DBT volume image, for which the activated navigation image has been provided, is regarded as being an activated DBT volume image of an activated breast;
• determining a CAD marker associated with the indicated two-dimensional location by a CAD marker determination unit, wherein the determined CAD marker is regarded as being an activated CAD marker, and determining another CAD marker of the other DBT volume image of the activated breast, which corresponds to the activated CAD marker, based on the provided correlation scores;
• determining a first slice position (z) defining a position of a slice of the activated DBT volume image, which includes a three-dimensional location of the activated CAD marker, and determining a second slice position (zc) defining a position of a slice of the other DBT volume image, which includes a three-dimensional location of the other CAD marker, by a slice determining unit;
• and
• controlling the display unit to display the slice of the activated DBT volume image at the determined first slice position (z) and the slice of the other DBT volume image at the determined second slice position (zc).
