    目鏡式功能磁共振刺激系統


    Visuastim digital由世界知名的功能磁共振配套產品供應商Resonance Technology公司研發,其被廣泛應用于任務態fMRI實驗及給予被試提供放松的掃描環境,雙眼裸眼3D立體呈現,每個微顯示屏在0.25平方英寸的面積上集成了1,440,000個像素,給予被試極佳的視覺體驗,即使最小的文本信息也可清晰的顯示。雙向立體聲聽覺系統,超薄設計的耳機兼容大部分線圈,并提供被試麥克風方便與主試溝通或用于聽覺或語言學研究。整個系統最高兼容3T-7T場強的磁場環境。產品全線取得美國FDA及歐洲CE認證。

    視覺目鏡:

    • 裸眼3D顯示功能,可方便進行視覺及虛擬現實研究;

    • 85HZ超高刷新率,給予被試流暢視覺體驗;

    • 30度廣角視野,沉浸式視覺體驗,完全消除被試幽閉恐懼;

    • 可選配眼動追蹤,用于后期更多行為學數據需要;

    • MR激光連接技術,確保圖像清晰,明亮及還原度高。
                                                  


    聽覺系統:

    • 雙路立體聲,高保真還原聽覺刺激;

    • 可有效降噪30db;

    • 內置主動降噪麥克風,適合語音、語言學研究;

    • 500-10K高頻率響應范圍。
