Premarket evidence — what FDA accepted
source quote (p.7)
“The ACUSON Sequoia, Sequoia Select, Origin and Origin ICE Diagnostic Ultrasound Systems are multi-purpose, mobile, software-controlled, diagnostic ultrasound systems with an on-screen display of thermal and mechanical indices related to potential bio-effect mechanisms.”
source quote (p.7)
“The system supports the Ultrasonically-Derived Fat Fraction (UDFF) measurement tool to report an index that can be useful as an aid to a physician managing adult and pediatric patients with hepatic steatosis.”
source quote (p.14)
“The UDFF algorithm remained unchanged and is the same for both adults and children. The algorithm for UDFF was not retrained and remained unchanged.”
