Technological Pillars of mQuadro:


Hardware Foundation

High speed, high capacity hardware components enable rapid processing of large amounts of acoustic data and enable the other three technological pillars that underpin mQuadro technology. With state-of–the art central processing, expansive memory capabilities and a solid state drive, mQuadro technology allows imaging, color, and Doppler to be taken to the next level producing outstanding results that benefit patient outcomes.


Fundamental Image Processing

Patented, intelligent processes that direct unique and innovative approaches to digital signal processing expand the possibilities for ultrasound image creation and optimization. Traditional post-acquisition image optimization is based on simple image analysis of both B-mode and color Doppler data sets. With mQuadro, optimization is based on image segmentation analysis and comparison to an anatomical structure database that minimize inherent artifacts, which can improve image quality.


Advanced Parallel Processing Technology

mQuadro’s powerful parallel processing is a technique that can interpret millions of instructions per second. This architecture captures an enormous amount of acoustic data from each transmit operation and performs digital beam reconstruction along with optimized focal processing to create real-time images with exceptional resolution and uniformity. In traditional serial processing of a received acoustic data set, the results were slow and inefficient signal processing. Parallel processing powered by mQuadro results in faster and more accurate and effective data signal processing which may assist in diagnosis.


Front End Signal Processing

AFRT is a method of exercising precise software control over both transmitted acoustic beam and efficient, fast receive data processing. Traditional transmit/receive methods result in increased clutter, lower signal to noise ratio, and slower acquisition times. The integration of AFRT into the front end of mQuadro platforms results in less clutter, improved signal to noise ratio and significantly faster data acquisition times which translates into:

Single Crystal Technology

Single crystal technology provides better acoustic/electrical (piezoelectric) energy conversion which results in better penetration and higher sensitivity. This yields a wider acoustic bandwidth which results in better penetration, improved spatial resolution, and more versatile applications.

Imaging results include:

  • Better signal-to-noise ratio (SNR)
  • Use of higher frequencies to image deeper structures
  • Easier and faster acquisition of images across all body types
  • Better image clarity across all body types

ZONE Sonography Technology (ZST)

Software-based, next-generation technology and the source of Living Technology.

ZONE Sonography Technology (ZST) is a revolutionary, software-driven approach to acoustic data acquisition and image formation that breaks the barriers of conventional ultrasound imaging. Using a variable number of large imaging “ZONES”, ZST is capable of utilizing up to 90% more ultrasound data than conventional ultrasound imaging platforms and at speeds 10 times faster. This expanded acoustic data set is retained and processed by patented high-speed digital processing techniques and software algorithms that are radically different from slow and cumbersome hardware-based imaging methods.

Living Technology

ZONE Sonography Technology is a constantly evolving, software-based technology, or a “Living Technology”. Living Technology is the ZST approach to providing customers with easily upgradable ultrasound enhancements based on its unique and proprietary ZONE Sonography Technology. These upgrades secure product investment protection by ensuring that ZST based platform remain at the cutting edge of imaging performance excellence throughout the system’s entire life cycle.

Key Advantages of ZONE Sonography Technology

Advanced Acoustic Acquisition

Acquisition and software processing of large ZONES of acoustic data creates individual ultrasound image frames 10 times faster than conventional line-by-line beam forming methods. This results in crystal clear, real-time imaging with an extremely fast and accurate temporal display of both anatomical motion and hemodynamic states. Advanced Acoustic Acquisition also reduces tissue motion artifacts and ensures consistent stellar image quality while in simultaneous triplex mode. This unique technological capability delivers superior image quality for all types of patients and across all ultrasound modes, increasing diagnostic confidence in every clinical application.

Dynamic Pixel Focusing

Radically different from conventional imaging, Dynamic Pixel Focusing provides exquisite spatial resolution and image uniformity from skin line to the deepest depths. Using advanced software algorithms, individual frames are created pixel-by-pixel focusing each point, on both transmit and receive, rendering an ultrasound image that is optimally focused in every frame, at every depth and every time. Dynamic Pixel Focusing assures a faster and more precise diagnostic process across all clinical applications by eliminating the need for operator-selected focal zone placement.

Sound Speed Compensation

Another unique and patented engineering breakthrough that differentiates ZST from traditional hardware-based beam forming platforms is automated digital Sound Speed Compensation (SSC). Historically, ultrasound imaging systems have been calibrated to the inaccurate assumption that ultrasound propagates through all human soft tissue at a velocity of 1,540 meters per second. In fact, many factors affect the actual speed of sound in a particular tissue and failure to compensate for these differences diminishes and limits spatial and contrast resolution in conventional ultrasound systems. At the touch of a button, SSC automatically samples the tissue being examined and recalibrates the software to reflect its specific speed of sound. The resulting enhancements in image quality provide another powerful clinical tool that increases diagnostic confidence, especially when examining diseased organs and structures at deeper depths.

Total Recall Imaging

As ZST captures and stores the complete acoustic raw data set, Total Recall Imaging (TRI) allows the user to retrospectively modify numerous imaging parameters and optimize clinical information. It eliminates the need for repeat scanning and improves patient throughput. TRI also permits off-boarding of in-phase quadrature (IQ) data for processing and analysis in advanced imaging and tissue characterization research applications; the vanguard of "virtual histology".
