1. A system for automated identification of volumes of interest in brain image data, the system comprising:
one or more processors; and
computer memory storing instructions that, when executed by the processors, cause the processors to perform operations comprising:
receiving image data of a brain having header data and voxel values, wherein the voxel values represent an interruption in blood supply of the brain when imaged;
extracting the header data from the image data;
populating an array of cells with the voxel values;
applying a segmenting analysis to the array to generate a segmented array;
applying a morphological neighborhood analysis to the segmented array to generate a features relationship array, wherein the features relationship array includes features of interest in the brain indicative of stroke;
identifying three-dimensional (3D) connected volumes of interest in the features relationship array; and
generating output, for display at a user device, indicating the identified 3D volumes of interest.
