The Next Evolution in Ultrasound, designed for high expectations

ARIETTA 850 ultrasound platform responds to high expectations to answer the ever increasing demands of medical professionals.

ARIETTA 850’s fundamental performance has been refined with the goal of creating an ultimate ultrasound platform, based on its newly-developed, Pure Symphonic Architecture.

The ultrasound platform features:

  • Pure Imaging evolved to fit your sight offering unprecedented image quality, optimized to user preferences
  • Seamless workflow evolved to fit your touch providing excellent ergonomics, easy-of-use, precision and efficiency for a comfortable examination experience
  • Advanced applications to fit your process such as Fusion imaging (RVS) in support of RFA, Elastography, Fetal 3D and many other technologies which help you to increase your diagnostic confidence

Linear 4G CMUT (Capacitive Micro machined Ultrasound Transducer)

Hitachi was the first company to put the MATRIX CMUT (Capacitive Micro machined Ultrasound Transducer) into practical use, using the next generation silicon wafer technology.
This innovative MATRIX linear transducer 4G CMUT (Capacitive Micro machined Ultrasound Transducer) offers a one-probe solution for whole body imaging, supporting not only scanning of superficial structures, but also deep-seated organs and blood vessels.

Real-time Virtual Sonography (RVS)

The novel advanced imaging mode, Real-time Virtual Sonography (RVS), positions Hitachi in the multidisciplinary diagnostic and interventional fields of urology, radiology, internal medicine, gastroenterology, oncology and surgery.
The Real-time Virtual Sonography (RVS) displays the real-time ultrasound image simultaneously with the corresponding CT or MRI virtual multi-planar rendered view reconstructed from a stored volume data set.

2D Tissue Tracking (2DTT)

The 2D Tissue Tracking (2DTT) is an advanced tool which allows users to track the displacement of the cardiac tissue by using a novel and accurate algorithm of “Speckle Tracking”. Doppler based methods such as Tissue Doppler Imaging are limited in evaluating the displacement velocity of the tissue due to angle dependency. This new software allows the detection of velocity components perpendicular to the beam which is impossible with conventional Doppler techniques. By tracking, image to image, the natural patterns of the cardiac tissue on B-Mode images, the 2DTT permits the user to quantitatively evaluate the movement and the thickening of the myocardium.

Real-time Tissue Elastography (RTE)

RTE is an emerging diagnostic tool for the assessment and real-time colour display of tissue elasticity. This 2nd generation ultrasound modality has proven applications in breast, prostate, thyroid and pancreatic disease and where diagnostic biopsy is indicated, RTE allows more accurate localization and targeting of lesions.

Shear Wave Measurement (SWM)

SWM can be classified as a Point Shear Wave Speed Measurement according to the guideline of the World Federation for Ultrasound in Medicine and Biology (WFUMB), and measures Shear Wave Propagation Velocity (Vs).
SWM features the display of a reliability indicator (VsN) for the Shear Wave Propagation Velocity measurement (Vs) and automatically makes multiple Vs measurements within a Region of Interest (ROI) with a single button press. The percentage of correctly detected measurements is displayed quantitatively as the efficacy rate (VsN).
In summary, reproducibility and reliability are the key issues for shear wave measurement.


eFLOW is a high-definition blood flow imaging mode with drastically improved spatial and temporal resolution. In eFLOW it is possible to display blood flow information with higher sensitivity and resolution than with conventional methods. This enables detailed observation of fine blood vessels such as those inside a tumor, which were difficult to display separately in conventional methods. eFLOW has a resolving power that can separately display the hepatic artery running alongside the portal vein.

Dual Gate Doppler

The Dual Gate Doppler generates a full FFT analysis and display from two separate sample gates allowing measurements from two different locations, during the same cardiac cycle.

For example: PW/PW, PW/TDI or TDI/TDI
