GE Healthcare, the health care arm of General Electric Co. (NYSE: GE), is buying CHCA Computer Systems Inc. for an undisclosed amount.

CHCA, headquartered in Montreal, provides operating room management and analytics. The company develops the Opera software, which is used in operating rooms to provide real-time data during surgery.

The deal comes as GE Healthcare actively tries to increase its software footprint. The transaction follows the company's acquisition of API Healthcare, a software developer for the health care sector, in January. 

Barrington, Ill.-based GE Healthcare provides medical technologies and services, including medical imaging, software, information technology, patient monitoring, drug discovery and biopharmaceutical manufacturing technology.
