Meet the DAXTaking ultrasound to new depths 

Clinical Trends

dax clinical trends

Radiology departments are challenged by the prevalence of obesity and the increased utilization of bariatric surgical techniques, with ultrasound being the most highly impacted imaging modality.


Since the amount of tissue on a patient’s body can negatively impact the quality of the soundwaves and subsequent image coming from the scanner, it is estimated that obese patients are 1.65x more likely than others to have significant undiagnosed medical conditions2 and nearly 50% of all cancer patients younger than 65 were associated as overweight and obese.3

ACUSON Sequoia

Obese patients often require excessive pressure that can result in overexertion of the upper extremity.

As a result of the excessive pressure that is often required to image bariatric patients, there is a high incidence of ultrasound work-related musculoskeletal disorders (WRMSD) among sonographers. According to a recent publication, patient obesity is reported as the most significant barrier to practicing ergonomic scanning techniques.4

Meet the DAX


To help you address your bariatric patient population, Siemens Healthineers conducted extensive research to find a solution that allows clinicians to image patients varying in size with confidence and clarity. From this research, a new transducer has emerged – DAX.

The new DAX (Deep Abdominal Transducer) is a unique and patented imaging transducer that allows clinicians to image high BMI patients with confidence. Together with the ACUSON Sequoia ultrasound system, you can now deliver images at depths up to 40 cm without compromising diagnostic quality.

High element density transducers allow dynamic elevation aperture control according to one’s imaging needs. By changing the shape of the acoustic transmit signal, clinicians are able to clearly focus on smaller regions of interest than ever before while maintaining elevation slice thickness throughout the image.

The DAX employs an advanced form of Multi-D beam formation for images at depths up to 40 cm, helping clinicians to better detect focal lesions in high-BMI patients and reduce diagnostic uncertainty and potentially unnecessary patient testing.
