ETG 100

Near-infrared light is used to measure relative hemoglobin levels in the cerebral cortex.

What's new is its measuring principle

Located at a depth of some 20mm from the scalp, the cerebral cortex controls high-level brain functions, such as muscular movements, recognition, language and thinking. Totally different from the conventional technology, Hitachi's Optical topography system provides a completely new means of assessing the activity status of the cerebral cortex.

As using the absorption characteristic of hemoglobin, the system provides simultaneous multi-channel measurements, and can display time-course changes in hemoglobin concentration in the from of a two-dimensional topographic motion image, making it easier to monitor the activity status of the cerebral cortex being examined.

Features

• A two-dimensional motion display of time-lapse changes in cerebrocortical blood volume.
• A non-invasive procedure with less patient restraint.
• A compact unit that can be wheeled anywhere, reducing environmental requirements.
• Can be used simultaneously with an MRI device or other modalities.
• Various probes for measurement target.
• Optional 3D measurement system to make activated areas clear in the brain.
