Siemens Healthcare agreed to buy the assets of Penrith Corp., a Plymouth Meeting manufacturer of ultrasound imaging systems, with an emphasis on smaller systems that can used in emergency departments, mobile hospitals used in the military, or triage centers used for natural disasters.

      The price was not disclosed, but Siemens said that all of Penrith’s roughly 20 employees would be offered jobs at Siemens. Penrith was founded in 2005.

      The company has raised $4.63 million in equity and debt since 2007, according to FormsD.com, an investment-tracking site.    – Harold Brubaker
