文摘
- •
Coherent hemodynamics spectroscopy (CHS) quantifies hemodynamic oscillations.
- •
Near-infrared spectroscopy can measure CHS spectra in a variety of tissues.
- •
A linear hemodynamic model yields biological meaning of CHS spectra.
- •
A nonlinear model is presented here to treat cases beyond the linear approximation.
- •
Cerebral autoregulation and blood flow are among the processes assessed by CHS.
