A common type of motion present in clinical magnetic resonance imaging examinations is rotational motion, such as that due to voluntary motion during head examinations. The correction scheme presented in this work offers a method for eliminating the effects of rotations within the imaging plane. Integral to the implementation of this technique is the concept and design of spatial-frequency-tuned markers, which are used to track the rotational motion. These studies showed that it is possible to… CONTINUE READING
