PROBLEM TO BE SOLVED: To correct luminance nonuniformity of images based on sensitivity distribution nonuniformity of an RF coil for part imaging without unnaturally raising the pixel value of a background noise area.SOLUTION: When correcting the luminance nonuniformity based on the nonuniform sensitivity distribution of the RF coil for part imaging in images obtained using the RF coil for part imaging, the sensitivity distribution of the RF coil for part imaging is acquired, a correction value for correcting the luminance nonuniformity is determined on the basis of the sensitivity distribution, and the processing of preventing the rise of the background noise of the images is performed when correcting the luminance uniformity of the images using the correction value.COPYRIGHT: (C)2012,JPO&INPIT【課題】 背景ノイズ領域の画素値が不自然に持ち上げられることなく、部位撮像用RFコイルの感度分布不均一に基づく画像の輝度不均一を補正する。【解決手段】 部位撮像用RFコイルを用いて得られた画像における、該部位撮像用RFコイルの不均一な感度分布に基づく輝度不均一を補正する際に、部位撮像用RFコイルの感度分布を取得し、その感度分布に基づいて輝度不均一を補正するための補正値を求め、補正値を用いた前記画像の輝度不均一の補正の際に、該画像の背景ノイズの持ち上がりを防止する処理を行う。【選択図】 図7
