Various methods are available to compute SNR. These methods differ in how noise is measured and are a balance between robustness and acquisition duration. A new single acquisition method is demonstrated that has the desirable attributes of both single image, and two-image techniques. The single acquisition is acquired with two times larger read direction field of view and matrix size. The resultant k-space data is undersampled into the even and odd data points. The resultant magnitude reconstructed images, with normal matrix size and image FOV, are effectively created simultaneously in time, eliminating any system drift artifacts in the noise measurement.
