SYSTEMS AND METHODS FOR MEASUREMENT ANALYSIS OF ANEURYSMS
Systems and methods for classifying and measuring a cerebral aneurysm of a parent vessel. The method includes identifying a potential aneurysm and determining whether the potential aneurysm is a saccular aneurysm type or a fusiform aneurysm type. If the potential aneurysm is the saccular aneurysm type then determining a neck-plane and a neck width of the neck-plane. If the potential aneurysm is the fusiform aneurysm type then determining a distal plane and a proximal plane.
