Aliasing artifacts occur in the phase encoding direction when the dimensions of the imaged object exceeds the field of view. Signal generated from outside the field of view appears as a superimposed object at the opposite edge of the image. Increasing the field of view, changing the gradient axes relative to the patient, or use of surface coils can reduce aliasing and are parameters which are controlled by the radiologist/technologist. The manufacturer may provide software packages which… CONTINUE READING
