Summary

The purpose of this study is to determine if Electrical Impedance Tomography (EIT) can produce reproducible and accurate images in people with stroke or head injury compared to existing standards such as MRI, CT.

Electrical Impedance Tomography is a relatively new medical imaging method, which has the potential to provide novel images of brain function. It is fast, portable, safe and inexpensive, but currently has a relatively poor spatial resolution. It produces images of the internal electrical impedance of a subject with stroke or head injury using rings of ECG like electrodes on the skin. EIT recording will take place as early as possible, usually within 24 hours of admission. Following completion of the recording, the EIT images will subsequently be analysed and compared to other imaging data for accuracy.

Conditions

  • Stroke
  • Craniocerebral Injuries

Interventions

DEVICE

Electrical Impedance Tomography

EIT comprises of a box of electronics similar in size to a video recorder, laptop computer and leads which link typically to 16 or 32 external ECG-like electrodes placed around the subject. Images are generated by applying tiny electrical signals through some electrodes and recording the resulting signals at others. The signals applied are completely safe, within established British and EU safety limits and cannot be felt.
