On the Amenability of Ghost Imaging to Large Parallel Acceleration Factors

Ioannis Koktzoglou¹, Robert R. Edelman¹

Ghost imaging is a newly proposed methodology for angiography that does not use image subtraction and depends on the presence of arterial ghost artifacts outside of the body. Presumably due to the sparsity of these ghost artifacts and the absence of background signal, the method is found to better support the use of higher parallel acceleration factors than does conventional subtraction-based MRA.
