Functional imaging with tomographic near infrared diffuse optical spectroscopy (DOS) can quantitatively measure tissue parameters such as the concentration of deoxy-hemoglobin (Hb), oxy-hemoglobin (HbO2), percent water (%water), and scattering power (SP). The purpose of this study was to evaluate the correlation between DOS functional parameters with pathologic outcomes. Patients with locally advanced...
Functional near-infrared spectroscopy (fNIRS) is an emerging technique for monitoring the concentration changes of oxy- and deoxy-hemoglobin (oxy-Hb and deoxy-Hb) in the brain. An important consideration in fNIRS-based neuroimaging modality is to conduct group-level analysis from a set of time series measured from a group of subjects. We investigate the feasibility of multilevel statistical inference...
In the measurement of brain function by using fMRI, increasing of blood flow and decreasing of deoxy-hemoglobin concentration as a cause of this increasing (BOLD: blood oxygenation level-dependent) are measured. And brain activity is evaluated as the function of BOLD signal. In the fMRI measurement, MRI data under stimulation and resting are measured periodically, and these data are compared and analyzed...
