GRUPPO INTEGRATO DI STIMOLAZIONE AUDIO-VISIVA E REGISTRAZIONE MOVIMENTI OCULARI PER RISONANZA MAGNETICA

摘要

The object of the present invention is an integrated unit for audio-visual stimulation and eye movement recording for magnetic resonance imaging which comprises two parts: a stereoscopic 3D projection part, far from the magnet and a compact part integral with the coil, which includes: a screen for stereoscopic vision, piezoelectric loudspeakers for a five channel listening, a video camera-IR illuminator assembly for bright pupil tracking at 40 cm from the subject. The system allows to use the entire width of the tracking field and thus to present stimuli with a wide visual field. The system is compatible with the high magnetic field environment of MR tomographs and with the use of coils having a particularly narrow radio frequency.
