Millions of people living in developing countries and in rural areas of developed countries tend to be distant from modern medical centers, and therefore cannot receive proper medical treatment. According to the World Health Organization, some three-quarters of the world’s population have no access to ultrasounds, X-rays, magnetic resonance images, and other medical imaging technology used for a wide range of applications, from detecting tumors to confirming signs of active tuberculosis infections. Professor Boris Rubinsky from the Hebrew University of Jerusalem has developed a new system that might replace the traditional medical imaging methods, solving these problems and offering faster and easier diagnosis in the field.
The researchers chose Electrical Impedance Tomography (EIT), which demonstrates the feasibility of using cell phones in medical imaging. EIT is based on the principle that diseased tissue transmits electrical currents differently from healthy tissue. The difference in resistance from electrical currents is translated into an image, which can be transmitted via cell phone technology.
