ARIETTA 850

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.

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 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

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)

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)

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.

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.

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. 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.
