Correction for intensity falloff in surface coil magnetic resonance imaging.

W W Brey1, P A Narayana.   

Abstract

A method has been developed to compensate for sensitivity variation in surface coil images. An algorithm to derive the surface coil profile by acquiring a crude body coil image of the region under study is presented and tested using a homogeneous phantom. Practical application is demonstrated on images of a tomato and rabbit acquired with a 2 T 33-cm bore magnetic resonance imager/spectrometer.
