Claim 0:
1. A computing device for perihematomal edema (PHE) analysis comprising:
a processor;
a network communication interface;
a memory in communication with the processor and having stored thereon, processor-executable instructions for causing the processor to perform operations comprising:
receiving, from a computerized tomography (CT) imaging device, a three-dimensional CT image of a patient exhibiting PHE in at least a portion of tissue surrounding and external to an intracerebral hematoma (ICH);
converting the three-dimensional CT image into two-dimensional CT image slices;
applying Hounsfield Unit (HU) windowing to each two-dimensional CT image slice to differentiate the ICH from the PHE;
converting each two-dimensional CT image slice into a feature vector;
passing the feature vectors to a convolutional neural network (CNN) model as input;
executing the CNN model using the feature vectors of the two-dimensional CT image slices 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.
