A, A phantom aneurysm model constructed of silicone elastomer tubing used to test the MAR algorithm prototype. Platinum coils were deployed in the aneurysm, and a small piece of polyurethane was placed inside a stent deployed across the aneurysm neck to model a clot. B and C, Uncorrected FDCT images acquired of the model constructed with stent, coils, and the simulated clot show streak artifacts created by the metal alloys of the stent and coils. D and E, Corresponding MAR-corrected FDCT images show reduced artifacts.
