A user interface using a wireless accelerometer-based controller (WiiTM, Nintendo, Kyoto, Japan) system was developed for navigation of the MR-endoscope system. The software enables the MR volume data to rotate by rolling the controller. The angles of roll and pitch of the controller acquired by acceleration sensors were sent to the image processing work station via Bluetooth. After evaluating the noise in the Bluetooth communications with phantom examinations, the usefulness of the controlling device was validated with the porcine gastric wall MR images. The resultant image process control indicates an acceleration censor can make the image manipulation more smooth and intuitive in an interventional MR suite.
