Talk:Electrical impedance tomography

New Picture
Andy Adler has made a new picture with calculated rather than guessed current streamlines. on the EIDORS web site. He has licensed it under CC so I am going to replace my old hand drawn version.Billlion (talk) 19:46, 2 November 2010 (UTC)

Regarding the caption
The caption says that the lines are red, but they seem to be blue? Mvsmith (talk) 22:57, 15 November 2010 (UTC)



Lines must be wrong
Current lines and equipotential lines MUST be orthogonal, and the ones displayed are not ... so something is wrong. —Preceding unsigned comment added by Alipaparu (talk • contribs) 16:32, 19 November 2010 (UTC)
 * You are right unless the tissue is highly anisotropic!Billlion (talk) 21:10, 6 June 2011 (UTC)
 * It is the caption that is wrongBilllion (talk) 05:35, 7 June 2011 (UTC)
 * The old version had stream lines and equipotentials from different drives. The new version has the same drive.Billlion (talk) 21:30, 10 June 2013 (UTC)

Improvement drive
We are here at the EIDORS code-a-thon and we are planning to improve the article especially on respiratory monitoring. We have uploaded this picture of a neonate with electrodes to replace the Brookes image. We are planning to include a reconstruction from the tutorial when we have updated the tutorial.Billlion (talk) 10:16, 3 July 2012 (UTC)

Improvement Drive II
At the meeting of the International Steering Committee on Biomedical Applications of Electrical Impedance Tomography in May 2015, the body that runs the annual conference on that topic, it was agreed we would try to have an improvement drive again. Members of the committee agreed to help translate or contribute to Wikipedia articles in their own languages taking EN as the main source where appropriate. This committee consists of leaders of the main research groups working on EIT around the world. Note however most are not experienced Wikipedians so please don't bite the newbie.

 * What do we think about the non-standard f-EIT a-EIT etc nomenclature?Billlion (talk) 09:58, 9 June 2015 (UTC)

Technical
Although I found the first few paragraphs readable, it goes into too much depth for an introduction and could be written in a more concise, less technical manner. $$|$$ ozhu  (talk·contribs) 17:45, 2 July 2015 (UTC)

Properties - suggested improvement / error correction
The first sentence of this section states:

"In contrast to most other tomographic imaging techniques, EIT does not apply any kind of ionizing radiation."

Whereas the Wikipedia article on tomography lists various tomographic techniques and significantly fewer than half appear to use ionizing radiation. However the vast majority are non contact techniques, so this is the most significant difference to most other tomographic imaging techniques.

I would suggest this sentence should be changed or removed or changed, e.g.

"In contrast to most other tomographic imaging techniques which are contactless and use various forms of radiation and magnetism, EIT requires multiple electrical contacts to the object being imaged."

I am not sure that properties is the appropriate title for this section either. As stated in a previous comment, the introduction is unnecessarily complex and the whole article could be significantly improved for readability. I would suggest more sections with titles to help describe the technique with better readability. Lkingscott (talk) 07:32, 11 July 2022 (UTC)

Article Moving/Renaming/Restructuring
The name Electrical Impedance Tomography is technically not a medical application, however, this article is purely about medical imaging. Electrical impedance technologies have been used in industrial processes, such as fluidized beds, pipelines, and other mediums where information about the phases present and the volume/size of these phases exists.

Either the current information on the article should be all part of a section on medical applications, or the article should simply be renamed, and another article on electrical impedance tomography should be created. The second option is likely better as this article is already quite long.

A based on a 2 minute search, a few articles and books discussing other applications of electrical impedance tomography can be found here:
