Examinations of the human lung under free breathing offer an increased patient comfort over those with breath holds. This increase in comfort generally comes at the cost of an increased scan time. To minimize this extra time we propose an efficient cartesian sampling scheme that employs oversampling of the k-space center. In conjunction with parallel imaging methods, artifact free volumetric images can be obtained in less than a minute.
