Compensation for surface coil sensitivity variation in magnetic resonance imaging.

P A Narayana1, W W Brey, M V Kulkarni, C L Sievenpiper.   

Abstract

A procedure which incorporates the aspects of both correction matrix and digital filtering to compensate for sensitivity fall-off of the surface coil has been applied to clinical imaging. In this method the surface coil profile is determined using the surface coil image and a crude body coil image. Our results indicate that the corrected surface coil image exhibits the homogeneity of the body coil image while essentially preserving the sensitivity of the surface coil image.
