1. A method for evaluating a stroke patient's brain, the method comprising:
capturing computed tomography angiography (CTA) images of the stroke patient's brain;
analyzing the captured CTA images with a machine learning-based algorithm that has been trained to quantify a size of an ischemic core based upon similar analysis that has been performed on computed tomography perfusion (CTP) images; and
generating results based solely upon the analysis of the CTA images by the machine learning-based algorithm that provide an indication as to whether the stroke patient is eligible for endovascular stroke therapy (EST).
