Key Technologies include:

• Native TEQ™ ultrasound technology: a Siemens-exclusive image processing technology that consistently enhances image quality across all patients and clinical applications.
• High-Resolution Color Flow: applies chirpcoded excitation to color Doppler to address spatial resolution, low flow sensitivity, penetration, hemodynamics and small vessel visualization.
• Cadence™ contrast pulse sequencing technology*: the industry's most sensitive contrast agent imaging detection utilizing both non-linear fundamental and higher order harmonics to provide enhanced diagnostic confidence.
• Clarify™ vascular enhancement technology: a Siemens-exclusive real-time, adaptive enhancement technique that utilizes color Doppler energy data to enhance B-mode image quality.
• MultiHertz™ multiple frequency imaging technology: provides broad bandwidth for independent frequency selection eliminating the need to change transducers during exam.

Matched response Technology

Sequoia™ matched response technology measures and adapts to patients' individual acoustic properties for consistent, reliable exams. Matches transmit and receive functions to heighten clinical specificity, optimize diagnostic outcome and improve workflow across applications.

Native Patient Specific Imaging

Native patient specific imaging (NPSI) is the only ultrasound technology to form images based on the individual signature of each and every patient.  This revolutionary technology enables the ACUSON Sequoia ultrasound system to use a patient specific feedback loop, utilizing all available acoustic information (both phase and amplitude) to optimize to the patient's individual acoustic properties. The system detects, measures, and adapts in real-time the transmit and receive functions to offer unparalleled image quality.

Coherent Imaging Technologies

• Coherent image formation uses both phase and amplitude information to form an image resulting in:
  • Increased temporal and spatial resolution
  • Greater dynamic range and sensitivity
  • Increased frame rates
• Coherent pulse formation precisely controls the transmitted waveform for increased imaging performance
• Programmable waveform generator generates complex transmit waveforms enabling:
  • Native™ tissue harmonic imaging to eliminate body wall artifacts and acoustic noise
  • Chirp coded excitation for increased penetration at high frequencies with higher resolution imaging, and high frame rate while reducing motion artifacts
  • Dynamic Transmit Focus to dynamically focus the transmitted beam at multiple focal depths without decreasing frame rates
