一、產(chǎn)品概述
英國(guó)UCL大學(xué)生物醫(yī)學(xué)光學(xué)研究實(shí)驗(yàn)室研制開發(fā)的NTS近紅外光學(xué)腦成像系統(tǒng)是一種可以提供256個(gè)fNIRS多通道功能、高規(guī)格的功能性近紅外光譜成像(fNIRS)設(shè)備。NTS系統(tǒng)用途廣泛,幾乎可以以任何配置輕松應(yīng)用于成人、兒童或嬰兒。系統(tǒng)靈活且適應(yīng)性強(qiáng),硬件、信號(hào)檢測(cè)方法和帽子的設(shè)計(jì)旨在讓用戶以任何可以想象的配置來(lái)布置光源和探測(cè)器光纖,從而可以在任何被試上進(jìn)行任何大腦皮層區(qū)域的研究。NTS可以獲得高質(zhì)量的數(shù)據(jù),其光源-探測(cè)器的間距范圍從12mm到40mm以上,可對(duì)大腦淺層組織和較深的大腦區(qū)域進(jìn)行采樣。系統(tǒng)與各種神經(jīng)監(jiān)測(cè)、神經(jīng)成像和神經(jīng)刺激設(shè)備*兼容,高質(zhì)量的玻璃光纖,確保系統(tǒng)的技術(shù)與EEG、tDCS和TMS設(shè)備之間的干擾為零,可實(shí)現(xiàn)多模態(tài)腦功能測(cè)試和團(tuán)體超掃描測(cè)試。
功能近紅外光譜成像技術(shù)(fNIRS)使用光來(lái)監(jiān)測(cè)人腦功能。該技術(shù)通過將近紅外光傳輸?shù)筋^皮,然后在幾厘米遠(yuǎn)的地方檢測(cè)散射回頭皮的光,可以測(cè)量大腦中氧合和脫氧血紅蛋白濃度的變化。由于腦活動(dòng)和局部血流之間存在密切的關(guān)系,血紅蛋白濃度的這些變化提供了腦功能的可靠度量。NTS fNIRS系統(tǒng)處于這一技術(shù)增長(zhǎng)的前沿,以易于使用和便攜的方式安全地研究人腦功能。
相比其他腦功能成像技術(shù),近紅外腦功能成像技術(shù)具有良好的空間分辨率、較高的采樣率、更多的測(cè)量指標(biāo)、良好的舒適性和較低的成本等優(yōu)點(diǎn),在認(rèn)知神經(jīng)科學(xué)和臨床研究中有著較為廣泛的應(yīng)用;同時(shí)由于其抗運(yùn)動(dòng)干擾性強(qiáng)、便攜可穿戴等特點(diǎn),系統(tǒng)在運(yùn)動(dòng)科學(xué)、腦機(jī)接口等領(lǐng)域的價(jià)值也逐漸被研究者所認(rèn)識(shí)。具體應(yīng)用案例包括駕駛員的認(rèn)知負(fù)荷研究、多模態(tài)腦機(jī)接口研究、操作人的情緒狀態(tài)研究等。
二、產(chǎn)品特點(diǎn)
NTS系統(tǒng)的核心優(yōu)勢(shì):靈活的系統(tǒng)配置與高質(zhì)量的數(shù)據(jù)。
●內(nèi)置的靈活性:NTS從第一天開始就盡可能被設(shè)計(jì)得靈活且適應(yīng)性強(qiáng)。系統(tǒng)的硬件、信號(hào)檢測(cè)方法和帽子旨在讓用戶以任何可以想象的配置來(lái)布置NTS光源和探測(cè)器光纖,從而可以在任何被試上進(jìn)行幾乎任何皮層區(qū)域的研究。
●高質(zhì)量的數(shù)據(jù):大量研究表明,短距離fNIRS通道可用于顯著提高fNIRS測(cè)量的可靠性和特異性。這是因?yàn)?/span>fNIRS測(cè)量對(duì)頭皮血管中血容量的變化敏感。短距離fNIRS測(cè)量?jī)H對(duì)這些表面信號(hào)敏感,因此可以用來(lái)改善fNIRS的大腦特異性測(cè)量。NTS成像系統(tǒng)的靈活性使用戶能夠輕松將多個(gè)短距離測(cè)量結(jié)果納入其陣列設(shè)計(jì),而無(wú)需光纖或單獨(dú)的探測(cè)器。系統(tǒng)的光源-探測(cè)器的間距范圍從12mm(對(duì)淺層組織進(jìn)行采樣)到40mm以上(對(duì)皮層和較深的大腦區(qū)域進(jìn)行采樣)。
●多模態(tài)腦功能測(cè)試:NTS系統(tǒng)與各種神經(jīng)監(jiān)測(cè)、神經(jīng)成像和神經(jīng)刺激設(shè)備*兼容。系統(tǒng)使用高質(zhì)量的玻璃光纖,確保我們的技術(shù)與EEG、tDCS和TMS設(shè)備之間的干擾為零。NTS系統(tǒng)還旨在促進(jìn)fNIRS和EEG的同時(shí)使用:系統(tǒng)的帽子允許EEG電極直接集成在NTS光纖上,NTS系統(tǒng)可以輕松地與幾乎所有EEG設(shè)備同步。

三、功能應(yīng)用
1、fNIRS Hyperscanning腦功能超掃描系統(tǒng):NTS提供了fNIRS Hyperscanning腦功能超掃描解決方案,fNIRS超掃描系統(tǒng)的模塊化設(shè)計(jì)可以提供2人以上實(shí)時(shí)同步進(jìn)行腦功能超掃描測(cè)試使用并支持*的數(shù)據(jù)同步。fNIRS超掃描技術(shù)提供了比fMRI超掃描技術(shù)更為真實(shí)的實(shí)驗(yàn)環(huán)境、比EEG超掃描技術(shù)更好的空間精度,正成為認(rèn)知與行為研究中的重要研究工具。
2、EEG-fNIRS多模態(tài)腦功能測(cè)試系統(tǒng): UCL高密度近紅外腦功能成像系統(tǒng)可以和NeurOne高精度腦電測(cè)量系統(tǒng)搭配使用,將EEG和fNIRS進(jìn)行整合發(fā)揮二者的優(yōu)勢(shì),EEG的時(shí)間分辨率高,但是空間分辨率低;fNIRS的時(shí)間分辨率低,實(shí)時(shí)性較差,但是空間分辨率高。為了準(zhǔn)確、全面、實(shí)時(shí)的測(cè)量大腦在認(rèn)知過程中的活動(dòng),實(shí)現(xiàn)全面、實(shí)時(shí)的腦成像方式無(wú)疑是一種更好的策略。結(jié)合EEG與fNIRS的多模態(tài)腦成像技術(shù)在認(rèn)知神經(jīng)科學(xué)研究中有著很好的應(yīng)用前景,同時(shí)還可搭建多模態(tài)腦-機(jī)接口系統(tǒng)。
