The ability of a conventional high-field MR scanner to function as a dynamic, flexible real-time interventional imaging tool is appealing as closed-bore systems become more open and accessible. Currently available fast imaging techniques can acquire images with a rapid frame rate, but real-time modification of the image plane requires an active or passive navigational sensor. We have developed a system to enable real-time interactive MRI on closed-bore scanner using a passive magnetic field sensor (PMFS).
