Area of Science:

  • Neuroscience
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Cerebral cortex activity monitoring is crucial for understanding brain function and disease.
  • Existing methods for measuring brain activity can be invasive or restrictive.
  • Near-infrared spectroscopy (NIRS) offers a non-invasive approach to assess hemodynamic changes.

Purpose of the Study:

  • To introduce the Optical Topography System "ETG-100" developed by Hitachi Medical Corporation.
  • To highlight the system's capability in measuring cerebral hemoglobin volume changes.
  • To showcase the system's potential applications in neuroscience research and clinical diagnostics.

Main Methods:

  • The ETG-100 utilizes near-infrared light, similar to spectroscopy.
  • It non-invasively measures changes in oxyhemoglobin, deoxyhemoglobin, and total hemoglobin in the cerebral cortex.
  • The system displays these hemoglobin changes in 2D images.

Main Results:

  • The ETG-100 provides a non-invasive, compact, and cost-effective method for monitoring cerebral hemodynamics.
  • It allows for real-time visualization of hemoglobin changes in the brain.
  • The system demonstrates features like reduced patient restraint.

Conclusions:

  • The Optical Topography System ETG-100 is a novel modality for researching higher-order brain functions, such as language processing.
  • Potential applications include studying brain function diseases in newborns and detecting cerebral blood flow infarction.
  • The system offers a promising tool for advancing neuroscience and clinical brain imaging.
