Abstract
In an MR system employing a phased array surface coil, a method is provided for reducing artifacts in an MR image acquired from a region of an object lying within a specified field of view, wherein the field of view has a dimension extending between first and second boundary limits. The method includes the step of positioning the phased array surface coil, which comprises a linear array of coil elements, in selected spatial relationship with the object region. The method further comprises selecting a particular coil element for use in acquiring MR data only if the coil element lies at least partially in a range which extends along the phased array and has a length equal to the field of view dimension, the range lying between positions respectively corresponding to the first and second boundary limits. Each of the selected coil elements is operated to acquire MR data from respectively corresponding subregions of the object region, and the MR image is constructed only from MR data acquired by respective selected coil elements.
