Quantitative Brain Tissue Oximetry, Phase Spectroscopy and Imaging the Range of Homeostasis in Pigletissue hemoglobin oxygen saturation was unclear and where the CW instruments were unsuitable for proper quantitative measurements [1, 2]. The development of the IQ Phase Meter has greatly simplified and made reliable the difficult determination of precise phase and amplitude signals from brain. This

Arterial Pulsations are Present in One Third of the Human Cranial Vascular Volume Penetrated by Nearear infrared spectroscopy (NIRS, 10 Hz sampling frequency, 769 nm). The NIR absorption is decomposed in pulsatile and non-pulsatile components by digital filtering. The time course of absorption changes of these components after sudden intravenous injection of indocyanine-green (ICG) is used to esti

Absolute Frequency-Domain Pulse Oximetry of the Brain: Methodology and Measurementsscopy is described. This method is based on the quantitative measurement of the tissue absorption spectrum, which is used to determine global SO.. From the amplitude of absorption changes caused by arterial pulsation oscillations, in the range of 633-841 nm, the fdSaO. can be calculated. During deox

The Influence of a Clear Layer on Near Infrared Spectrophotometry: Comparison of Measurements in a L At the head, the clear cerebrospinal fluid (CSF) layer may violate this assumption. The aim was to estimate the error in the TOI values caused by the CSF layer in vitro and to confirm the results .. The liquid phantom mimicking the neonatal head, consisted of a spherical shell of silicone filled wi

Brain Tissue and Sagittal Sinus pO2 Measurements Using the Lifetimes of Oxygen-Quenched Luminescenceinescence of ruthenium compounds immobilized at the tip of fiber-optic optodes (Oxylite system). The system was used to measure the pO. in brain tissue (thalamus and hypothalamus) and in the sagittal sinus of isoflurane anesthetized rats at different FiO.’s. The pO. recorded in the hypothalamus (HPt
