  Modern MRI scanners utilize one or more arrays of small receive-only coils to
collect k-space data. The sensitivity maps of the coils, when estimated using
traditional methods, differ from the true sensitivity maps, which are generally
unknown. Consequently, the reconstructed MR images exhibit undesired spatial
variation in intensity. These intensity variations can be at least partially
corrected using pre-scan data. In this work, we propose an intensity correction
method that utilizes pre-scan data. For demonstration, we apply our method to a
digital phantom, as well as to cardiac MRI data collected on a commercial
scanner by Siemens Healthineers. The code is available at
