Publication Overview with our NIRS devices in 2022 – Brain
We are proud that several papers using our (f)NIRS devices to measure brain activation from different cortical areas and in various application fields were published in 2022. Read this blogpost to get an overview of application areas (f)NIRS can be used in, and which devices can be applied. Also, find highlighted publications per category that were performed with our devices in 2022.
The use of Inertial Measurement Unit (IMU) to detect motion artifacts
Due to its portability, NIRS and fNIRS devices are often used to measure brain and muscle activity during studies that involve movement. To detect motion artifacts that might occur during these experiments, some of our devices, for instance, Brite and PortaLite MKII, incorporate an inertial measurement unit (IMU). Read this blog post, to learn more about the technology behind IMU and how it is used to detect motion artifacts.
Tissue Saturation Index (TSI) - Absolute oxygenation measure in local tissues
Tissue Saturation Index (TSI) is an absolute measure for the local tissue oxygenation in tissue beneath the sensor. To obtain TSI, a technique called Spatial Resolved Spectroscopy (SRS) is used. TSI can be measured in both brain and muscle. Some of our devices provide the possibility to acquire absolute TSI, next to relative concentration changes in oxy- and deoxygenated hemoglobin. Learn more about the TSI and how to correctly use it in this blogpost.
Measuring brain and muscle oxygenation simultaneously using only one device
Interest and importance of simultaneously measuring brain and muscle oxygenation is increasing in various research fields. Our new device, the PortaLite MKII assessment of oxygenation of different tissues and locations by using only one device. Read more about the PortaLite MKII, application possibilities, and features in this blog post.
The PROHEALTH Project – Investigating orthostatic hypotension in elderly by performing continuous NIRS measurements in a home-based setting
Orthostatic hypotension is a form of low blood pressure that is characterized by drops in blood pressure when standing up from a lying or sitting position and frequently occurs in elderly subjects. The PROHEALTH project aims to implement home-based and continuous Near-Infrared-Spectroscopy (NIRS) measurements to detect orthostatic hypotension using the PortaLite (MKII). Read this blog post more about the PROHEALTH project and which targets are followed to reach the goal.
