Abstract
Systems and methods of are disclosed for providing visual feedback to a subject during magnetic resonance imaging, where the visual feedback is associated with input provided by the subject to a magnetic resonance compatible touch panel. A video camera is employed to record video images of the interaction between the subject and the touch panel, and the video images are processed to generate a real-time video signal including a rendering of the input provided to the touch panel and the interaction between the subject's hands and the touch panel. The real-time video signal is provided to the subject as visual feedback, and is displayed within a time duration that is sufficiently fast to avoid the detection of the visual feedback as an error signal with the subject's brain in relation to the sense of proprioception. A measurement of the force applied to the touch panel by the subject may be recorded and employed when rendering the real-time video. The systems and methods may be employed for a wide range of diagnostic and therapeutic procedures involving magnetic resonance imaging.
