Siemens Healthineers launched a new ultrasound system, ACUSON Sequoia, during the 3rd National Ultrasound Conference held in Hanoi on January 11.

A general imaging ultrasound system, ACUSON Sequoia was developed in response to one of the most prevalent challenges in ultrasound imaging today: the imaging of different sized patients with consistency and clarity.

With its new Deep Abdominal Transducer (DAX), a new high-powered architecture with innovative updates to elastography and contrast-enhanced ultrasound, the new ACUSON Sequoia produces penetration of up to 40 cm.

“With its powerful architecture and innovative features, the new ACUSON Sequoia expands precision medicine by enabling high-resolution imaging that adapts to patients’ size and personal characteristics, contributing to a more confident diagnosis,” said Mr. Fabrice Leguet, General Director of Siemens Healthineers Vietnam.

According to the World Health Organization, 1.9 billion people globally are reported as overweight, with 650 million classified as obese. In Vietnam, the number of overweight people has increased four-fold compared to ten years ago and accounted for 18.3 per cent of the population in 2016. Because ultrasound imaging relies on the sending and receiving of echo signals to produce images, the deeper an echo signal needs to penetrate the more attenuation occurs, resulting in image quality degradation.

In response, Siemens Healthineers built the entirely new ACUSON Sequoia system to adapt to the “BioAcoustic Variations” of each patient, with characteristics that include tissue density, stiffness, and absorption. The new ACUSON Sequoia provides high-resolution InFocus imaging throughout the entire field of view, from the near field to the far field, in real-time. Therefore, there is no need to adjust the focal point of the scan, resulting in faster scan times without compromising frame rates and resolution. The new ultrasound system also offers high resolution color flow, up to three times the sensitivity (compared to ACUSON S3000), and up to 20 per cent deeper penetration.

In addition to increased rates of obesity, the prevalence of liver disease is also on the rise. Clinicians utilize ultrasound elastography to determine shear wave speed, a parameter correlated with tissue stiffness in the liver that can correlate to chronic disease progression. Imaging in these patients can be challenging, particularly in larger patients where the signals are attenuated. The innovative power architecture of the new ACUSON Sequoia provides six times the energy capacity available for shear wave elastography, enabling imaging at greater depths and a reduction in image variability.
