Hitachi Highlights Arietta 850 Premium Ultrasound System at RSNA 2017

December 5, 2017 — Hitachi Healthcare exhibited their latest premium ultrasound system, the Arietta 850, at the 2017 Radiological Society of North America (RSNA) Annual Meeting, Nov. 26-Dec. 1 in Chicago. The system, which received U.S. Food and Drug Administration (FDA) 510(k) clearance in November, offers a collection of features designed to improve image quality, speed workflow and extend the utility of ultrasound in radiology departments. Arietta 850 also supports what Hitachi calls the world’s first widely-available probe that uses capacitive micro-machined ultrasound transducers (CMUT) rather than piezoelectric crystals to transmit and receive the ultrasound signal.

The new system builds upon the advanced capabilities of Hitachi’s Arietta family of ultrasound scanners, adding features like eFocusing, which removes the need for focal zone adjustments by dynamically focusing from the near to far-field of the image. It also expands interventional capabilities through a collection of features that work in conjunction with Hitachi’s Real-time Virtual Sonography fusion software to automatically perform fusion registration, compensate for needle flexion during biopsy procedures, and deliver real-time visual maps of estimated radiofrequency (RF) ablation zones.

The new CMUT probe, the SML44 linear array, was introduced at the European Congress of Radiology and has received FDA 510(k) clearance. The design enables an ultra-wide bandwidth of 2-22MHz, allowing a single probe to address multiple clinical needs and to adapt to a wide variety of body habitus.
