Analysis of intracranial blood vessels

A system comprising:

• at least one hardware processor,
• a non-transitory computer-readable medium storing instructions that, when executed by the at least one hardware processor, cause the at least one hardware processor to perform operations comprising:
• obtaining an image of a brain of an individual;
• identifying, using the image, a blood vessel located in the brain of an individual based on a template that indicates locations of a number of blood vessels located in a human brain, the template including a composite image generated based on a number of reference images with the number of reference images being obtained from a number of individuals and including brains and other features associated with the brains of the number of individuals;
• determining a starting point with respect to the blood vessel, the starting point indicating a first voxel of the image that is included in a path of the blood vessel within the brain of the individual;
• determining a path along the blood vessel based on density values corresponding to the blood vessel, the density values indicating an amount of contrast between portions of the image related to the blood vessel and background portions of the image;
• determining an endpoint of the blood vessel based at least partly on the template;
• determining that the blood vessel terminates before the endpoint;
• and
• determining, based on the blood vessel terminating before the endpoint, a probability that an abnormality is present with respect to the blood vessel.
