US 11,885,861 B2 · 3-dimensional representations of post-contrast enhanced brain lesions

Abstract

3D MRI images of the brain may be created and acquired. After administration of contrast, brain lesions and other abnormalities may be identified and isolated from the 3D MRI images, with each lesion serving as a region of interest (ROI). 3D region of contrast enhancement images may be created from segmented 3D MRI images and different regions of contrast enhancement of the brain lesion may be depicted. Saved regions of contrast enhancement may be converted into stereolithography format, maximum intensity projection (MIP) images, and/or orthographic projection images. Data corresponding to these resulting 3D region of contrast enhancement images may be used to create 3D printed models of the isolated region of contrast enhancement. Analysis of the 3D brain region of contrast enhancement images and the 3D printed region of contrast enhancement models may enable a more efficient and accurate way of determining brain lesion risk factors and effective treatment regimens.

Dependent claims

A system for creating 3-dimensional (3D) representations of post-contrast enhanced brain lesions, the system comprising:

a computer system comprising at least one processor configured to:
receive one or more 3D images of a brain;
enable an identification of one or more regions of contrast enhancement in the one or more 3D images of the brain;
enable a segmentation of the one or more 3D images, the segmentation enabling an isolation of the one or more regions of contrast enhancement;
enable a creation of one or more 3D region of contrast enhancement images based on the segmentation, the one or more 3D region of contrast enhancement images comprising one or more region of contrast enhancement characteristics;
enable a comparison of the one or more region of contrast enhancement characteristics of the one or more 3D region of contrast enhancement images with one or more predetermined region of contrast enhancement characteristics;
and
enable a determination of a category of the one or more regions of contrast enhancement based on a match between the one or more region of contrast enhancement characteristics of the one or more 3D region of contrast enhancement images and the one or more predetermined region of contrast enhancement characteristics.
