Siemens introduced its new Acuson Antares ultrasound system and upgrades to its Acuson Sequoia ultrasound platform, both designed to deliver improved breast imaging, at the Radiological Society of North America meeting in Chicago this week.
The new Antares system offers an elasticity imaging technology package, which is designed to allow physicians to accurately distinguish characteristics of breast lesions, more clearly demonstrating relative tissue stiffness or hardness, infiltration and cystic regions. This new technology is intended to reduce reliance on invasive breast biopsy procedures. The Antares system is also equipped with tissue stabilization for improved detail and contrast resolution, and the new Fetal Assessment Application technology provides broad 3D/4D acquisition, rendering and post-processing functionality.
The new high-performance imaging release for the Sequoia ultrasound system includes the Advanced SieClear Spatial Compounding technology with Dynamic TCE capabilities. In addition, two new transducers will be available for the Sequoia, including the 17L5 HD transducer — a high-density ergonomic probe that delivers detailed imaging of small parts, breast and subtle pathologies — and the 9L4 transducer, a one-transducer solution that addresses cerebrovascular, peripheral arterial and deep venous imaging.
Antares receved FDA clearance last week, and both Antares and Sequoia will be commercially available early next year.
