Mathematical Insights for Medical Imaging


A team of mathematicians and engineers at Rensselaer Polytechnic Institute(RPI) has been working on a new techology for medical imaging. Thistechnology, still under development, is called Electrical Impedance Imaging.

It works by applying tiny electrical currents through electrodes placed on theskin, measuring the corresponding voltage response, and using the results toprovide an image of the body's tissues and fluids. (This works as differentbody parts have different electrical properties.)

This figure shows the impedance image of a simulated heart and lungs.

For more information, see the article Mathematical Insights for MedicalImaging by Barry Cipra, which appeared in Volume 2 ofWhat's Happening in theMathematical Sciences.
