A billion people have difficulty getting access to an x-ray, and that says nothing about access to MRIs or CAT scans. Over the past few years, [Jean Rintoul] has been working on a low-cost way to image the inside of a human body using nothing more than a few electrodes. It can be done cheaply and easily, and it\u2019s one of the most innovative ways of bringing medical imaging to the masses. <a href=\"https:\/\/www.crowdsupply.com\/mindseye-biomedical\/spectra\" target=\"_blank\" rel=\"noopener noreferrer\">Now, this is a crowdfunding project<\/a>, aiming to provide safe, accessible medical imaging to everyone.<\/p>\n<p><a class=\\'blog-photo\\' href=\"https:\/\/hackadaycom.files.wordpress.com\/2019\/04\/spectrabiomed.png\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" data-attachment-id=\"352872\" data-permalink=\"https:\/\/hackaday.com\/2019\/04\/06\/tomography-through-an-infinite-grid-of-resistors\/spectrabiomed\/\" data-orig-file=\"https:\/\/hackadaycom.files.wordpress.com\/2019\/04\/spectrabiomed.png\" data-orig-size=\"600,600\" data-comments-opened=\"1\" data-image-meta=\"{\u201caperture\u201d:\u201d0\u201d,\u201d credit\u201d:\u201d\u201c,\u201d camera\u201d:\u201d\u201c,\u201d caption\u201d:\u201d\u201c,\u201d created_timestamp\u201d:\u201d0\u201d,\u201d copyright\u201d:\u201d\u201c,\u201d focal_length\u201d:\u201d0\u201d,\u201d iso\u201d:\u201d0\u201d,\u201d shutter_speed\u201d:\u201d0\u201d,\u201d title\u201d:\u201d\u201c,\u201d orientation\u201d:\u201d0\u201d}\" data-image-title=\"spectrabiomed\" data-image-description=\"\" data-medium-file=\"https:\/\/lifeboat.com\/blog.images\/tomography-through-an-infinite-grid-of-resistors2.jpg\" data-large-file=\"https:\/\/hackadaycom.files.wordpress.com\/2019\/04\/spectrabiomed.png?w=600\" class=\"alignright\" src=\"https:\/\/lifeboat.com\/blog.images\/tomography-through-an-infinite-grid-of-resistors2.jpg\" alt=\"\" width=\"400\" height=\"400\" srcset=\"https:\/\/lifeboat.com\/blog.images\/tomography-through-an-infinite-grid-of-resistors2.jpg 400w, https:\/\/hackadaycom.files.wordpress.com\/2019\/04\/spectrabiomed.png?w=250&h=250 250w, https:\/\/hackadaycom.files.wordpress.com\/2019\/04\/spectrabiomed.png 600w\" sizes=\"auto, (max-width: 400px)  100vw, 400px\" \/><\/a><br \/> It\u2019s called Spectra, and uses electrical impedance tomography to image the inside of a chest cavity, the dielectric spectrum of a bone, or the interior of a strawberry. Spectra does this by wrapping an electrode around a part of the body and sending out small AC currents. These small currents are reconstructed using tomographic techniques, imaging a cross-section of a body.<\/p>\n<p>[Jean] gave a talk about Spectra <a href=\"https:\/\/hackaday.com\/2019\/01\/07\/towards-low-cost-biomedical-imaging\/\">at last year\u2019s Hackaday Superconference<\/a>, and if you want to look at the forefront of affordable medical technology, you needn\u2019t look any further. Simply by sending an AC wave of around 10kHz through a body, software can reconstruct the internals. Everything from lung volume to muscle and fat mass to cancers can be detected with this equipment. You still need a tech or MD to interpret the data, but this is a great way to bring medical imaging technology to the people who need it.<\/p>\n<p><a href=\"https:\/\/hackaday.com\/2019\/04\/06\/tomography-through-an-infinite-grid-of-resistors\/\" target=\"_blank\" rel=\"noopener noreferrer\"><\/p>\n<div style=\"clear:both;\">Read more<\/div>\n<p><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>One of the vast untapped potentials of medicine is the access to imaging equipment.
