Abstract
A method of assessing rupture risk of an aneurysm from time-resolved images includes injecting a contrast enhancing agent into a patient with an aneurysm, using an electrocardiogram (ECG) signal to trigger an image acquisition run, wherein a sequence of 2D X-ray fluoroscopic images is acquired along with a corresponding ECG signal value, rotating a C-arm attaching the X-ray fluoroscopic imaging apparatus during said image acquisition run, wherein the images in said X-ray fluoroscopic image sequence are acquired from a rotating viewpoint, sorting the images in said X-ray fluoroscopic image sequence into time windows of the cardiac cycle based on the ECG signal, and constructing one or more 3-dimensional (3D) angiography image volumes of said aneurysm from said 2D fluoroscopic image sequence.
