Medical Advances—Through Your iPhone?
Researchers are beginning to understand how mobile phones can cut costs, help solve rural health-care problems, and even reduce medical errors by Olga Kharif
Bioengineering professor Boris Rubinsky has what he hopes is the perfect antidote to bulky, expensive, hard-to-use medical machines: the mobile phone.

Despite all the advances in medical diagnostics, two-thirds of the world's population has no access to imaging technologies. Worse, about half of the imaging equipment sent to developing countries goes unused because local technicians aren't trained to operate it or lack spare parts, according to the World Health Organization. But thanks to the proliferation of cellular and other wireless networks, researchers are stepping up efforts to deliver crucial medical services from afar. "You go through
From Ultrasounds to Heart Monitors
Rubinsky is hardly the only medical researcher who sees this potential. Indeed, of some 30 health-care-related projects at various universities recently funded by Microsoft (MSFT) Research, 17 involve cell phones. One team, at
Cell phones may also help reduce the frequency of medical errors. Researchers at startup Gentag have developed disposable wireless Band-Aids containing radio frequency identification (RFID) chips that transmit key information to a cell phone. As a nurse is about to administer a drug, the Band-Aid may warn that the patient is allergic to it. The Band-Aids, expected to be introduced commercially in
Apple's (AAPL) hit iPhone, with its large color screen and full Web access, has been a boon for some graphics-rich medical applications. A software company called Life Record is using the iPhone to help physicians view patients' medical records, including electrocardiograms and brain scans, on the go. "Since the iPhone release, our business has quadrupled," says Michael Pike, Life Record's chief software architect. Doctors can also use Life Record to order prescriptions, an area where many medical errors occur.
With the iPhone spurring more handset makers to introduce similarly robust devices, the
Medical Record-Keeper
Consumer versions of mobile medical software may also see a boost. This June, Life Record plans to introduce an application that will allow individuals to have access to their own medical records via an iPhone for $50 a year. When visiting a new doctor or specialist, iPhone-toting patients will be able to pull up all of their medical information, including past X-rays and another physician's notes, by connecting with Life Record's servers over the Internet.
