1. A method for measuring morphological parameters of an intracranial aneurysm image, comprising:
segmenting an intracranial parent artery image from three-dimensional Digital Imaging and Communications in Medicine (DICOM) data of Digital Subtraction Angiography (DSA);
segmenting the intracranial aneurysm image on the intracranial parent artery image, wherein the segmenting the intracranial aneurysm image on the intracranial parent artery image comprises computing the centerline and radius of the parent artery on the intracranial parent artery image to segment the intracranial aneurysm image;
generating an aneurysm neck using the segmented intracranial aneurysm image, wherein the geometric center of the aneurysm neck is considered as the center of the aneurysm neck; and
measuring morphological parameters of the intracranial aneurysm image based on the center of the aneurysm neck.
