Siemens adds AI Abdomen as part of Acuson Sequoia 3.5

Siemens Healthineers has introduced Acuson Sequoia 3.5, a major software and hardware update to the Acuson Sequoia ultrasound system that leverages AI-powered features for improved workflow and efficiency. Acuson Sequoia 3.5 features AI Abdomen with improved ergonomics and new solutions for breast and MSK imaging.

AI Abdomen reduces sonographer hand motion by up to 89 per cent compared with manual examinations, says Siemens, and up to 44 per cent compared with protocol examinations. The improved ergonomics of AI Abdomen benefit ultrasound users who have reported pain during scanning, related to pressure applied to the transducer, abduction of the arm and twisting of the neck and trunk.

AI Abdomen is said to improve both examination and reading workflow through view identification and protocol standardisation, with an algorithm that automatically recognises and labels 17 anatomical views and calculates 12 key measurements.

Acuson Sequoia 3.5 also delivers a combination of exclusive technologies for breast imaging enabled by proprietary algorithms and the new HLX transducer, which is the company’s highest frequency linear transducer. The proprietary next generation 2D Shear Wave technology adapts to better identify and display stiff lesions in the breast, while the HLX transducer provides penetration and resolution, providing clinicians with the necessary diagnostic information to see and reduce false negatives.

“I am impressed by the advancements in the Acuson Sequoia 3.5,” said professor of radiology at Imperial College London Professor Adrian Lim. “The anatomy recognition and measurement of AI Abdomen could significantly simplify the abdominal examination, and I was equally impressed by the image resolution, penetration and ergonomics of the new HLX transducer.”

The transducer also addresses the MSK clinician’s need to visualise large in-motion tissues and small, superficial structures for conditions such as tendon tears and inflammatory arthritis. The lightweight transducer, designed with an ergonomic grip and narrow shape, allows for constant light pressure and tight access, and reduces strain and pressure during scans.
