ACUSON Sequoia Diagnostic Ultrasound System
Overview
The ACUSON Sequoia Diagnostic Ultrasound System, developed by Siemens Healthineers, is a premium ultrasound platform engineered to address the challenges of imaging diverse patient populations with consistency and clarity. It leverages innovative BioAcoustic imaging technology, which adapts to individual patient characteristics like tissue density and stiffness, to deliver high-resolution images across varying body types, including those with high BMI.
Key to its performance are InFocus imaging, which provides fully focused images throughout the field of view without manual focal zone adjustments, and InTune transducer technology, designed for optimal acoustics across various clinical use cases.
The system integrates AI-powered tools for enhanced workflow efficiency, automating tasks such as measurements and image labeling, and offering features like AI Abdomen for standardized exams. It supports a comprehensive suite of advanced applications, including Contrast Enhanced Ultrasound (CEUS), Shear Wave Elastography (SWE), and Ultrasound Derived Fat Fraction (UDFF), enabling precise tissue characterization and quantification.
Designed with user-centric ergonomics, the ACUSON Sequoia aims to improve diagnostic confidence, reduce variability, and streamline clinical procedures across a wide range of medical specialties.
