Passivation for capacitive sensor circuits, which overlies the capacitive sensor electrodes and is normally conformal to the electrodes and the underlying interlevel dielectric, is planarized by forming a layer of flowable oxide over the electrodes before forming the passivation. The system comprises a displaying unit, inputting unit, approximating unit, and locating unit. After recorded radiation image information is read from the stimulable phosphor panel by the reading unit, the stimulable phosphor panel is fed to the erasing unit, which erases remaining radiation image information from the stimulable phosphor panel. A raw magnetic resonance imaging data is calculated based on statistic property of each point and a magnetic resonance imaging sequence to be applied.
