Achieve unparalleled penetration without compromise with the ACUSON Sequoia ultrasound system

An ultrasound system created with users and patients in mind

Example of the DAX improving diagnostic accuracy in the high BMI patient when conventional ultrasound is limited. ACUSON Sequoia with DAX enabled a quality evaluation of this patient's liver and identified multiple mobile gallstones not identified on the conventional ultrasound technology.

Nearly half of all U.S. adults are obese.1 Radiology departments are challenged by this prevalence of obesity since the amount of tissue on a patient's body can negatively affect the quality of the image coming from the scanner.2 As a result, obese patients are 1.65x more likely than others to have significant undiagnosed medical conditions.3

But what if you could improve diagnostic accuracy in a patient population often limited by traditional ultrasound technology? And acquire those images ergonomically?

The ACUSON Sequoia ultrasound system powers the patented and industry-exclusive DAX (Deep Abdominal Transducer), enabling unprecedented imaging throughout 40 cm depth through an advanced form of Multi-D beam formation.

The ACUSON Sequoia, alongside the DAX, will finally enable clinicians to image high BMI patients with confidence.
