Visual stimulation at high fields is challenging due to the long magnet bores. In this work an LCD system for fMRI at 7T is presented which can be placed close to magnet iso-center. MR-compatible LCD illumination is achieved with 100 white LEDs. RF Noise measurements did not show RF-induced artifacts. Visual stimulation fMRI studies could be performed with the new presentation tool.
