Claim 12:
13. A method of perihematomal edema (PHE) analysis comprising
receiving, via a network communication interface of a computing device, from a computerized tomography (CT) imaging device, a CT image of a patient exhibiting PHE in at least a portion of tissue surrounding and external to an intracerebral hematoma (ICH);
separating the CT image into CT image slices;
applying Hounsfield Unit (HU) windowing to each CT image slice to differentiate the ICH from the PHE;
converting, via a processor of the computing device, each CT image slice into a feature vector;
passing the feature vectors to a convolutional neural network (CNN) model as input;
executing the CNN model to obtain an estimate of change in PHE volumetry distinct from the ICH using at least one secondary performance parameter including a Hausdorff distance; and
based on the estimate of change in PHE volumetry, determining a change in a medical status of a PHE volume of the patient according to whether the PHE volume is expanding or shrinking.
