Paper Abstract

This paper presents a quick and efficient way to detect and correct the linear and constant image-phase terms associated with MR images. We show that this correction provides us with the knowledge of the exact location of the DC term in k-space, which proves to be useful in the detection of x and y motion parameters. In addition, by displaying the real positive part of the image after the proposed correction, we can reduce background noise, motion artifacts and flow artifacts. Examples, analyses and results are provided to demonstrate the usefulness of the proposed detection and correction method.
