The subject device consists of a mobile console with keyboard. specialized controls, a color video LCD display with electronicarray transducers. It has the same general appearance, dimensions and weight as the unmodified device, it is a Track 3 generalpurpose imaging and analysis system providing real-time digital acquisition, processing and display capability intended for general radiology imaging and evaluation with some cardiology and vascular applications. The device is a general-purpose ultrasound system.

The GE Healthcare Voluson S6, Voluson S8 Ultrasound System did not require a clinical study to support its substantial equivalence. The device was evaluated for acoustic output, biocompatibility, cleaning and disinfection effectiveness, as well as thermal, electrical, electromagnetic, and mechanical safety, and found to conform to applicable medical device safety standards. The manufacturer asserts that its performance is substantially equivalent to predicate devices.
