Big medical data

With the recent launch of MIT's Institute for Medical Engineering and Science, MIT News examines research with the potential to reshape medicine and health care through new scientific knowledge, novel treatments and products, better management of medical data, and improvements in health-care delivery. At the end of 2012, the National Public Radio show "Fresh Air" featured a segment in which its linguistics commentator argued that "big data" should be the word of the year. The term refers not only to the deluge of data produced by the proliferation of Internet-connected, sensor-studded portable devices but also to innovative techniques for analyzing that data; and big data has received a good deal of credit for Barack Obama's victory in the last presidential election. Certainly, the term was in heavy use around MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), which in 2012 launched a new big-data initiative called bigdata@CSAIL. Several of the researchers affiliated with bigdata@CSAIL are developing new techniques for processing medical data, to make it more accessible to both physicians and patients and to find correlations that could improve diagnosis or choice of therapies.
