Surface coil intensity correction (SCIC) using proton density-weighted images (PD-SCIC; A-C) and SSFP images (SSFP-SCIC; D-F). B1-field inhomogeneity was approximated using a third-order surface fit to myocardial and body signal intensities on PD (A) or SSFP (D) images in order to generate an intensity bias field (B and E), which was subsequently applied to the perfusion image series. The corrected PD and SSFP images are displayed in C and F respectively.
