Why is EIT so hard, and what are we doing about it?
EIT images the impedance within a body from electrical stimulations and measurements on its surface. It shows promise for thoracic, brain, breast, abdominal and prostate imaging. Those of us working in EIT have written an introductory paragraph like the previous one, many, many times. Each time we write it, we try to compress the text, just a little more. Why? We are looking forward to the day when there is no longer a need to explain EIT; when there is no longer the need to call it a promising, 'new' technology. Instead, we would like to write, 'based on evidence of improved patient outcomes and safety, EIT devices are increasingly used ...', and provide the references to prove it. This editorial reviews how far along this road we have come.
