PURPOSE : Tumor grading plays an essential role in the optimal selection of solid tumor treatment. Noninvasive methods are needed for clinical grading of tumors. This study aimed to extract parameters of resting state blood oxygenation level-dependent functional magnetic resonance imaging (RS-fMRI) in the region of glioma and use the extracted features for(More)
At present, an effective detecting method for brain function impairment for the patients with the glioma is urgently needed in clinic, because it may help us understand its pathogenesis. This paper proposes a method of combining diffusion tensor tracing technology and 'small world' network. It utilizes the degree of brain function network to study complex(More)
PURPOSE Brain tumor patients are usually accompanied by impairments in cognitive functions, and these dysfunctions arise from the altered diffusion tensor of water molecules and disrupted neuronal conduction in white matter. Diffusion tensor imaging (DTI) is a powerful noninvasive imaging technique that can reflect diffusion anisotropy of water and brain(More)
In order to choose a fast and efficient real-time method in beta wave information extraction, we compared the result and the efficiency of the information separation of both fast Fourier transform (FFT) and wavelet transform of EEG beta band in the present paper. Our work provides the basis for the EEG data come from the real-time health assessment of 3DTV.(More)
At present, navigation path deviation caused by brain shift is the main factor that affects the accuracy of neurosurgical navigation. A new method of near infrared spectroscopy (NIRS) based neurosurgical navigation is presented in the paper. The correlation between NIRS optical parameters and medical image is used and the gray information of navigation path(More)
