We describe a phantom which enables EEG and near-infrared optical tomography to be performed simultaneously over the same volume. The phantom provides a surface electrical contact impedance comparable to that of the human scalp, whilst also possessing an optical scattering coefficient and electrical conductivity equivalent to that of brain tissue. The construction of the phantom is described, as is the resulting simultaneous EEG and near infrared optical tomography experiment, which, to our knowledge, is the first performed on a scale comparable to that of the infant human brain. This imaging experiment successfully shows the suitability of this phantom construction for the assessment of simultaneous EEG and near infrared optical tomography systems.
我们描述了一种体模，它能够在同一区域同时进行脑电图（EEG）和近红外光学断层扫描。该体模提供的表面电接触阻抗与人类头皮相当，同时还具有与脑组织相当的光学散射系数和电导率。本文描述了该体模的构建方法，以及由此进行的同步脑电图和近红外光学断层扫描实验，据我们所知，这是首次在与婴儿人类大脑规模相当的情况下进行的此类实验。该成像实验成功地表明了这种体模构建对于评估同步脑电图和近红外光学断层扫描系统的适用性。
