Functional brain imaging has tremendous applications. The existing methods for functional brain imaging include functional Magnetic Resonant Imaging (fMRI), scalp electroencephalography (EEG), implanted EEG, magnetoencephalography (MEG) and Positron Emission Tomography (PET), which have been widely and successfully applied to various brain imaging studies.(More)
A method of feature extraction based on principal component analysis (PCA) to identify drugs packed in anthropomorphic phantom was proposed. An energy dispersive X-ray diffraction spectrometer was used to acquire the spectra of drugs and the other materials. Features of spectra were extracted by PCA which excels in analyzing high-dimensional data.(More)
