Premarket evidence — what FDA accepted
source quote (p.5)
“The systems are full-featured Track 3 ultrasound systems, primarily for general radiology use and specialized for OB/GYN with particular features for real-time 3D/4D acquisition. They consist of a mobile console with keyboard control panel; color LCD/TFT touch panel, color video display and optional image storage and printing devices. They provide high performance ultrasound imaging and analysis and have comprehensive networking and DICOM capability. They utilize a variety of linear, curved linear, matrix phased array transducers including mechanical and electronic scanning transducers, which provide highly accurate real-time three-dimensional imaging supporting all standard acquisition modes. The proposed Voluson Expert Series 22/20/18 adds additional AI software features SonoPelvicFloor and SonoLyst/ Sonolyst Live (workflow improvement) to the system.”
