【正文】 agic resonance better In the paper, a mathematical method called the singular value deposition (SVD) is used to depose the signals so as to identify neural stem cells Stem cells of the adult human nervous system What is magic resonance spectroscopy ? (MRS 磁振頻譜 ) ? Magic resonance spectroscopy is an important technique of magic resonance. ? In brief, chemicals containing protons have different spinning frequencies. MRS depicts the intensities of the chemicals at each frequencies (in the unit of ppm) Limitations of conventional methods NAA Cr Cho Fourier transform has limited capacities in resolving signal ponents. By contrast, singular value deposition (SVD) permits improved detection at low signaltonoise ratios and allows better resolution of signal ponents (modes) that are close to one another in a given frequency domain. ppm can not be resolved by FFT but can be by SVD SVD does this…… NAA Cr Cho ? hippocampus Before SVD After SVD signal processing 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
