Abstract
A system and a method for mapping lesions or damage instances of a brain. The method includes receiving a lesion segmentation mask for the brain and receiving a tractography atlas. A connectivity damage brain map is constructed from (i) superimposing the lesion segmentation mask and a tractography atlas-based image, and (ii) combining information from the lesion segmentation mask with information from the tractography atlas-based image. The tractography atlas-based image is an image obtained from the tractography atlas, and the tractography atlas-based image and the lesion segmentation mask are registered to a common space.
Claims6
A computer-implemented method for mapping connectivity damage of a brain, the method comprising:
- receiving a lesion segmentation mask for the brain;
- receiving a tractography atlas;
- constructing a connectivity damage brain map by
- (i) superimposing the lesion segmentation mask and a tractography atlas-based image;
- and
- (ii) combining information from the lesion segmentation mask with information from the tractography atlas-based image;
- wherein the tractography atlas-based image is an image obtained from the tractography atlas, and wherein the tractography atlas-based image and the lesion segmentation mask are registered to a common space.
A system for mapping connectivity damage of a brain, said system comprising:
- a first interface for receiving or acquiring a lesion segmentation mask for the brain;
- a memory for storing the lesion segmentation mask;
- a second interface configured for acquiring or receiving a tractography atlas;
- a control unit having a processor, said control unit being configured for spatially registering the lesion segmentation mask and a tractography atlas-based image to a common space, said control unit being further configured for automatically constructing a connectivity damage brain map from superimposing the lesion segmentation mask and the tractography atlas-based image, and from combining information from the lesion segmentation mask with information from the tractography atlas-based image, wherein the tractography atlas-based image is an image obtained from the tractography atlas;
- and
- a display connected to said control unit and configured for displaying the connectivity damage brain map construed by said control unit.
