IMAGE TECHNOLOGY & ERGONOMICS

Compound Pulse Wave Generator (CPWG+)

The most advanced broadband beam-forming technology combined with high speed image processing that allows for higher deﬁnition ultrasound imaging than ever before.

Symphonic Technology

Provides high quality imaging using an expanded range of harmonic signals. This technology results in excellent image resolution and sensitivity and improved penetration.

HI REZ

Clearly displays differences in tissues, reducing speckle noise while maintaining the frame rate. It can also display outlines more clearly by selectively emphasizing boundaries.

Compound Imaging

The ultrasound beam is transmitted and received in real time and in the multiple directions resulting in a reduction of speckle noise, suppression of artifacts, and improvement of contrast resolution allowing lesions to be clearly observed.

Image Optimizer

At the touch of a button the B-mode image is instantly optimized to the user’s preference. This technology continually monitors the user’s typical settings to optimally adjust the image when pressed resulting in less manual adjustments and more efﬁcient examinations.

Single Crystal Probes

A single crystal is used to provide the piezoelectric elements of the probe. Single crystal technology achieves higher sensitivity and wider bandwidths over standard piezoceramics.

FEATURES

ARIETTA 70 Features

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: LV inﬂow and PV ﬂow - for pseudonormalisation assessment

PW/TDI: E-wave, A-wave and e'- E/e', as a way of evaluating diastolic dysfunction

TDI/TDI: septal wall TDI and lateral TDI - evaluation of cardiac resynchronisation therapy

2D Tissue Tracking (2DTT) utilizing speckle technology

It is very simple to set the contours of the myocardium with the 2DTT in order to ﬁt the endo and epicardium and easily assess the parametric data and images. The 2DTT provides precise quantitative measurements and information such as:

Global Longitudinal Strain/Strain Rate and Radial Strain/Strain Rate Twist angle, displacement, wall thickening and various other parameters to visualize, quantify and analyze the myocardial mechanics.

Free Angular M-mode (FAM)

Three M-mode lines can be set at any position and angle simultaneously, thus eliminating the complications involved with usual ultrasound systems in getting accurate measurements when the conventional view cannot be acquired. Additionally,

wall motion at different positions can be compared simultaneously, making it possible to accurately measure an eventual delay.

Strain/Strain Rate

Conventional cardiac function analysis is focused on diagnosis of global heart movement. By opposition, Strain quantiﬁcations aim is to analyse cardiac function more locally and sensitively by focusing attention on myocardium areas themselves.

Strain analysis is used to examine the cardiac function by measuring the elongation and shrinkage of the regional myocardium between two designated points. Strain analysis is attracting attention because it is less affected by translation and tethering for correct evaluation of myocardial motion.

You can carry on analysis while making sure that ROI position and Strain length are adequately set (therefore tracking of the “objective part” ) and working by checking the ROI that automatically follows by velocity tracking and the SR marks.

Hitachi Aloka’s Velocity Tracking Algorithm to calculate STRAIN, based on the state of the art technology, makes it possible to automatically and easily track regional myocardium motion (Strain) while taking in consideration “twist” & “tethering” effects of the global heart movement.

Using line data (RAW), the TDI analysis software enables high frame rate for accurate analysis results.
