Innovation: Inova, the Northern Virginia hospital system, has signed a deal with Ion Beam Applications to provide proton therapy to cancer patients. Inova plans to start treating patients with protons — a form of radiation treatment — by 2020 at the Inova Schar Cancer Institute on the Inova Center for Personalized Health campus. New at the top: Virginia’s Center for Innovative Technology named a new leadership team to run its MACH37 Cyber Accelerator. Tom Weithman, who had served as chief investment officer, was appointed president, Jason Chen was tapped to be managing director for operations, and Mary Beth Borgwing was named managing director for cyber. They replace a team led by Rick Gordon. Acquisition: NCI, a publicly traded company that provides technology services to the Pentagon, the Department of Justice and others, has agreed to be bought by a private equity firm in a deal valued at $283 million. The buyer is H.I.G. Capital, a private-equity firm that specializes in leveraged buyouts of small and midsize companies.
