SPECTRA – OPEN SOURCE BIOMEDICAL IMAGING

Spectra brings open source biomedical imaging into the open with a development kit that is both safe and easy to use. It allows hackers and scientists to experiment with one of the technologies used in medical imaging — electrical impedance tomography (EIT). For the first time, anyone who wants to explore the fascinating world of medical physics can do so from their own home, without a multimillion-dollar CATSCAN.

SPECTRA – OPEN SOURCE BIOMEDICAL IMAGING

Electrical Impedance Tomography (EIT) can localize dielectric changes in the body such as lung changes or by used for gestural control. The Spectra device is wrapped around the thorax to map changes in the lungs. It can track lung volume, expansion and contraction in real-time of each lung individually alongside impedance cardiography of blood flow through heart valves.

Spectra can image lungs, monitor heart activity, and detect changes on materials like bones, tumors and strawberries. Since it can get a cross-section of whatever it’s wrapped around it’s also ideal for gestural recognition and could be used to help those with prosthetic limbs.
