Radiation-treatment equipment maker Accuray Inc. said Chief Financial Officer Derek Bertocci has resigned, effective Monday.
Bertocci had been Accuray's CFO since January 2009. The company did not say why he resigned, although in a statement Bertocci said he was "taking a break in my career and taking time to spend with my family." He will continue to consult with the company.
Accuray said its new CFO is Gregory Lichtwardt. Lichtwardt, 59, previously worked for nine years at Conceptus Inc., where he was CFO.
Conceptus was acquired by Bayer AG in June.
