摘要：

The possibility that a highly portable, fast, safe and affordable imaging system could obtain interpretable images of brain function in full- and pre-term neonates in a few seconds, has been explored in this paper. We have used a uniquely sensitive optical tomography system, termed phased array, which has revealed significant functional responses, particularly to parietal stimulation in normal and pathological states of neonate brain. This two-wavelength, frequency encoded phased array system can indicate the blood concentration and oxygenation change during the parietal brain activation in neonates. The preliminary clinical results are presented in this paper.
