New approach to 3D time‐resolved angiography

TRICKS is an acquisition and reconstruction method capable of generating 3D time‐resolved angiograms. Arguably, the main problem with TRICKS is the way it handles the outer regions of the k‐space matrix, leading to artifacts at the edges of blood vessels. An alternative to the data‐ processing stage of TRICKS, designed to better represent edges and small vessels, is presented here. A weakness of the new approach is an increased sensitivity to motion compared to TRICKS. Since this method can use the same data as TRICKS, a hybrid reconstruction method could conceivably be developed where the advantages of both approaches are combined.
