We propose a new method to compensate for distribution of receiving sensitivity in a body coil. It corrects a shading artifact that remains after compensation based on sensitivity ratio of surface and body coils. The method utilizes body coil sensitivity taken in advance with an uniform phantom. The body coil sensitivity is transformed by referring the ratio of intensity between channels. The method is intrinsically insensitive to tissue contrast because it is cancelled by taking ratio. The method is useful when the reference image has strong tissue contrast. The effect of proposed method is examined by phantom and volunteer study.
