The probe is the rst and main component o the long chain thata signal has to pass through, it represents the ultrasound beamtransmitter and the backscattered echo receiver. Esaote iQProbetechnology is o main importance to obtain a high signal to noiseratio, a sharp signal ull o inormation regarding spatial, contrastand temporal resolution. In addition it targets the optimization oergonomics and usability with the unique appleprobe design.

Based on iQProbe concept, eHD Technology introduces ur-ther improvements in terms o array material and acoustic lens.Thanks to the single crystal piezoelectric elements, the transducer

bandwidth is enhanced providing a better signal sensitivity. Whilea complete new design o precisely engineered matching layers isintroduced, the latter increases the number o layers and enhanc-es the quality acoustic lens. It is now available an extraordinaryimpedance optimization, which is one o the undamental objec-tive in order to obtain top signal sensitivity, imaging & Dopplerquality and new gel agents resistance.

“Diagnostic value enhancement and system usability optimization are the main key factors taken intoconsideration in the development of the eHD Technology. It focuses the whole ultrasound chain, fromthe transducer to the display, passing through signal processing and strategic features.”

eHD Pulser

Esaote fagship eHD Pulser is the core o the system’s ront endtechnology. It creates any kind o ultrasound beam waveorm.It is the powerul tool to drive any probe at the right signalwaveorm, thus enabling:• optimized and uniormed acoustic eld along the complete

line o sight to achieve image homogeneity;• optimized acoustical energy distribution within the whole eld

o view with no rame rate reduction;• uniorm energy distribution both in near and ar eld.

eHD Processing

eHD Technology introduces new perormance to XView real-timealgorithm, provides a urther signicant reduction in speckle, andenhances the visibility o the structures inside the human bodywithout changing the overall image appearance. eHD Technol-

ogy powered XView increases contrast resolution by increasingthe signal to noise ratio. The combined use, at the same time, oXView and MView Spatial Compound Imaging gives to the usera superior ultrasound imaging quality that extremely increasesdiagnostic condence and image readability.

tion generated by dedicatedalgorithm or optimized vesselborder detection. OptimizedCFM parameterization alongthe whole line o sight withan increased sensitivity also indepth.

eHD XFlow is a high resolution,high denition Doppler tech-nology which maximize spatialresolution and Doppler signalpenetration capabilities.

Work in Progress QDP (QualityDoppler Proles) Technology isa new Multigate Spectral Dop-pler technology that processesthe echo signals backscatteredrom multiple depths alongthe US beam, producing anddisplaying in real-time the so-called spectral prole.This is a matrix o power spec-tral densities corresponding

to the simultaneously inves-tigated depths. QDP technology investigates the “third dimen-sion o Doppler” in a graphical orm, where spatial distributionis on the vertical axis and velocity distribution on the horizontalone, while the brightness o any pixel describes the power o thecorresponding spectral density. In this way, QDP enables the si-multaneous analysis o dierent vessels and dierent blood fowcomponents within the same vessel in real time without ramerate loss.

eHD Technology ImagingeHD Technology Imaging rep-resents the window throughwhich the user is able to getthe diagnostic inormation he islooking or. Esaote has alwaysimplemented the latest visu-alization tools and technologiesin order to ensure clear images

ull o inormation.

ErgonomicsThe Esaote ultrasound systems are designed with a simple userinterace and personalized automation tools, intuitive and imme-diate menu. Ultrasound probes light and appleprobe ergonomicsreduce at the minimum any physical stress also in situations oelevated workload and patient trough-put. High system mobil-ity in terms o transportation handling and adaptability to thediverse physical characteristics and necessities o the operator.
