Pure Symphonic Architecture

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 OLED monitor: all technologies working together to realize the highest level of premium class performance.

Transducers/Frontend

4G CMUT

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.

C23RV/C23

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.

C23RV/C23

Variable Beamformer

eFocusing

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.

Focused at all depths

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.

Carving Imaging

OLED Monitor

image

The ARIETTA 850 has adopted the latest technology, 22 inch wide OLED Monitor for an optimum image display. Without requiring backlighting to function, the OLED Monitor displays true black so a previously unattainable contrast resolution can be achieved. It is the ideal monitor choice for diagnostic ultrasound, producing the highest quality grayscale display.

The ergonomic design of the ARIETTA 850 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.

Flexible Monitor Arm

image

The monitor arm mechanism supports a smooth back-and-forth movement of the screen during the examination without any change to the up, down, right or left position.

Protocol Assistant

image

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

image

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 850 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)*

image

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

image

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 850.

3D Sim-Navigator*

image

Provides simulation of single or multiple needle paths during navigation to a target with Real-time Virtual Sonography (RVS). The positional relationship between the marked target and needle paths can be assessed in real time using the 3D body mark, reconstructed from the virtual CT volume data, with additional C-plane display orthogonal to the needle path.

E-field Simulator*

image

A color map superimposed on the CT image simulates the distribution of the electric field (E-field) from the given location of multiple electrodes during RFA treatment.
The simulation can be made with different positions of the multiple electrodes to determine the optimal arrangement. This flexibility in planning the needle path can bring significant improvement to the treatment technique.

Elastography

Real-time Tissue Elastography (RTE)*

image

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 the breast, thyroid gland and urinary structures.
Using the abdominal convex transducer, it can also provide an estimation of fibrosis staging in patients with hepatitis C (LF Index).

Shear Wave Measurement (SWM)*

image

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)*

Shear Wave Elastography

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.

Combi-Elasto*

image

By integrating the two non-invasive methods for evaluation of liver tissue stiffness, namely RTE and SWM, it is possible to assess the chronological progression of liver inflammation and fibrosis with greater accuracy.
A combined simultaneous estimation of the degree of steatosis (ATT index) makes Combi-Elasto a comprehensive tool for the differential diagnosis of liver disease .

Fetal 3D/4D*

image

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.

Auto FHR+*

image

The fetal heart rate can be automatically calculated using a tracking ROI placed over the fetal heart on the B mode image in real time. This offers a safer and more objective measurement compared to conventional Doppler or M-mode methods. Furthermore, as this function is also available on the transvaginal transducer, assessment can be made from early gestation onwards.

Dual Gate Doppler

image

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.
