ARIETTA 850 SE ultrasound platform responds to high expectations to answer the ever increasing demands of medical professionals.ARIETTA 850 SE’s fundamental performance has been refined with the goal of creating an ultimate ultrasound platform, based on its newly-developed, Pure Symphonic Architecture.

Product Features

Technologies fostered by HITACHI to hone the high quality “sound” have evolved further giving life to Pure Symphonic Architecture.

The combination of transducer/frontend, variable beamformer, active backend, and monitor: all technologies working together to realize the highest level of premium class performance.



The evolution of CMUT (Capacitive Micro-machined Ultrasound Transducers), using next-generation silicon wafer technology has brought the full complement of ultrasound examination modes into practical use.
With super wide frequency bandwidth and high sensitivity the enhanced resolution is maintained in the far field.
CMUT can deliver a one-probe solution for a wide range of ultrasound examinations.


Micro convex transducer (single crystal) delivering high image quality and easy application in routine examinations. The transducer shape, as well as the performance of the piezoelectric element and heat dissipation structure, have been optimized to achieve both image quality equivalent to a conventional convex transducer, and low-stress operability.
In addition, it seamlessly supports examinations in various scenes, used in tandem with functions such as Wide Scanning, which enables a wider scanning angle, Contrast Harmonic Imaging, and a built-in(C23RV only) RVS magnetic sensor

Variable Beamformer


The eFocusing, newly developed transmission and reception technology, improves S/N and reduces focal dependency significantly.
Outstanding clarity of imaging from near to far field with less patient dependency is achieved.

Active Backend Plus

Active Backend, the system’s powerful image processing engine, has evolved to Active Backend Plus.

Carving Imaging

Carving Imaging is an image processing parameter that enhances tissue structure visibility. It helps to achieve clearer images with less noise, and contributes to ease diagnosis.


With a high contrast ratio and wide viewing angle, the LCD monitor gives a rich representation of the displayed image.

The ergonomic design of the ARIETTA 850SE minimizes operator fatigue. Supporting seamless workflow, the many easy-to-use functions shorten examination time and provide a more comfortable examination environment. As a result, the patient experience is also improved.

Protocol Assistant

Prior registration of routine protocols significantly reduces the operation steps necessary during the examination. Prompts for image store, alerts of mistaken image store repeats, all contribute to increased examination efficiency, accuracy and throughput.

Automated Measurement

Combined Setting of AFS/ASR

Auto Frame Selection (AFS) picks out the appropriate frame for measurement in Real-time Tissue Elastography. Assist Strain Ratio (ASR) automatically locates the measurement ROI. Complex, repetitive measurement steps can now be completed using a single button.

ARIETTA 850SE performs an extensive variety of advanced applications that offer support across a broad clinical range. With efficient support for rapid/accurate diagnosis, treatment guidance, and research opportunities, Hitachi creates new clinical value.

Detective Flow Imaging (DFI)*

The new imaging technology for visualization of low velocity blood flow below the previous detection threshold. The unique algorithm displays fine blood flow with greater resolution and sensitivity .

Evolving RVS* Features

Since its release in 2003, Hitachi’s Real-time Virtual Sonography (RVS) has continued to evolve to meet clinical needs. Significant further developments have been introduced with the ARIETTA 850SE.


Real-time Tissue Elastography (RTE)*

RTE assesses tissue strain in real time and displays the measured differences in tissue stiffness as a color map. Its application has been validated in a wide variety of clinical fields: for breast, thyroid gland and urinary structures.

Shear Wave Measurement (SWM)*

Shear waves are generated using a ‘push pulse’ to excite the tissues. SWM provides an assessment of tissue stiffness by calculating Vs, the propagation velocity of the shear waves. Hitachi’s SWM provides an additional reliability indicator, VsN, as an objective evaluation of the Vs measurement.

Shear Wave Elastography (SWE)*

SWE color-codes tissue stiffness based on the propagation velocity of shear waves. Further, it enables quantitative evaluation by quantifying the stiffness of any area falling within the ROI. SWE can be used to evaluate liver stiffness visually and non-invasively.

Fetal 3D/4D*

Three- and four-dimensional imaging can play a role as a prenatal communication tool connecting parents with their fetus. AutoClipper automatically defines the optimal cut plane removing placental or other unwanted tissue signals in front of the fetus, offering a clear surface-rendered fetal image.

Dual Gate Doppler

Enables observation of Doppler waveforms from two different locations during the same heart cycle. A combination of blood flow and Tissue Doppler waveforms enable measurements such as the LV diastolic performance indicator, E/e’ ratio, avoiding beat-to-beat variation. Simple measurements from two different waveforms can also be useful in the diagnosis of fetal arrhythmia.
