Solutions for Safety & Innovation

Diagnostics & Imaging

Ultrasonic Imaging is a key technology in many aspects of the healthcare industry. Real-time, moving images are now commonplace, providing clinicians with invaluable knowledge of internal anatomy. PZFlex has played a significant role in this progress having found widespread use globally with companies such as GE, Philips, Siemens, Hitachi and many more. The power of PZFlex allows engineers to accelerate design cycles via the accuracy and speed of its prediction, while reducing dependency on expensive fabrication of test devices.

Custom Analysis Tools

Extract important metrics quickly and effectively from simulations. Electrical Impedance, Admittance, Conductance, Beam Profiles, Efficiency and other common outputs are available from standard toolsets.

CMUTs

Fully simulate the nonlinear, coupled behaviour of CMUTs with electrostatic solver options. Contact and non-contact modes are supported, along with arbitrary drive conditions. Powerful solvers allow analysis of 3D array configurations coupled to electrical components.

Image
Phased Arrays

Simulate complete linear and 2D matrix probes. Analyse electrical and mechanical crosstalk, directivity, electrical impedance, beamforming and more. Advanced solvers enable large transducer models to be solved in hours rather than days.

Sub-wavelength Structures

Include microstructure detail, thin layers such as electrodes, and sub-wavelength targets in the simulation with ease. Mesh refinement allows for features smaller than the required mesh to be placed arbitrarily in the model.

Image
Electrical Circuits

Capture the full system by coupling electrical components into the FEA simulation. Model both transmit and receive electronics in the same simulation. Extract voltage, charge and current at any component in the circuit.

Piezo Material Characterization

Simulation results are only as accurate as the material properties used. Through advanced algorithms and ultra-fast numerical simulations, accurate material properties can be backed out from the measured electrical impedance of a sample.

HIFU and Therapeutics

In therapeutic applications, tissue ablation via HIFU promises a non-invasive surgical technique to help in the fight against cancer. PZFlex has supported developments in HIFU for 20 years by providing tools to simulate HIFU performance in realistic anatomical geometrics. Acoustic and thermal solvers allow designers and clinicians to analyse thermal deposition from acoustic pressure maps, providing better control over focal regions, exact tumour targeting and necessary exposure times to boost patient safety margins.

Image
Nonlinear Propagation

With transient solvers the nonlinear component of wave-propagation falls out naturally. Study the harmonics generated by shock-wave formation, and how this behaviour effects performance of the system, including thermal effects.

Import Tissue Maps

Importation from CT and MRI allows users to simulate their devices under realistic operating conditions. Beam divergence, reflections and pulse width can be quantified quickly. See where acoustic power is being deposited.

Image
Thermal Analysis

Ensure safe treatment planning by accurately simulating the thermal deposition and temperature rise from the ultrasound system. Include the effects of perfusion (blood flow) in the model to evaluate the optimal input configuration.

Frequency Dependent Damping

With frequency-depending damping models for acoustic and elastic materials, including viscoelastic behaviour, broadband performance is accurately captured. Capturing the crucial effects of damping ensure are more accurate thermal model can be achieved.

Image
Shear Wave Imaging

Investigate the performance of Remote Elastography systems in response to arbitrary drives, tissue maps, tissue properties and more. Perform the Acoustic Radiation Force simulations to extract accurate stresses and the resultant forces in the elastic tissue.

We use PZFlex from proof of concept to final design of complex ultrasonic transducers for the NDT of nuclear reactor components. PZFlex is a very precious tool for debugging spurious echoes occurring inside the transducer, and for making our design right first time.
  • Jean-Francios Saillant, Areva
Cutting edge research requires high-quality data, produced with rapid iteration. In work where time and accuracy are paramount, PZFlex delivers. Moreover, the support staff from PZFlex were outstanding in their willingness to help and work with us to produce exactly what we needed. Finally, all of this powerful software is relatively easy to learn and use, making PZFlex a clear leader for us. We could not recommend the product highly enough.
  • Sheridan Gho, UCSF
PZFlex offers insight into complex coupled electrical-mechanical-acoustic problems, which reduces the research and development timeframe for piezoelectric based devices.
  • Jay Bennett, Director of Transducer Technology at Ultreo Inc
We have found PZFlex to be an invaluable tool to aid efficient development of complex inspections scenarios. It has many flexible features that the user can tailor to their needs and the PZFlex team always offer great support.
  • Ailidh McGilp, Senior Project Engineer at Doosan Babcock
PZFlex helps gain insight into complex multi-modal ultrasonic transducers and helps reduce cost by virtual prototyping of design. As a consequence, the overall time to market and cost of development is reduced without sacrifice on performance of ultrasonic devices.
  • Mo Zarkan, Ultrasonic Engineer at Emerson
PZFlex ultrasonic simulation software has proven to be a valuable R&D tool as we continue to develop and enhance newer touchscreen technologies. PZFlex staff have continually provided direct, prompt and helpful support.
  • Dr. Joel Kent, Scientist at Elo Touch Solutions, Inc.
PZFlex is an essential tool in our modelling of ultrasonic transducers and in their application. It allows us to better understand how the design parameters and materials affect the performance of our new transducer designs before we proceed with expensive and time consuming manufacture. By simulating applications of our ultrasound systems this allows us to tailor bespoke solutions and accelerate the delivery of our research projects.”
  • Prof. Anthony J. Mulholland, BSc, MSc, PhD, FIMA, CMath, Head of Department Department of Mathematics and Statistics, University of Strathclyde
Modeling is essential in supporting common engineering practices in the design and development of high-quality transducers. PZFlex is an easy-to-use, reliable FEM software tool that allows our design engineers to expand beyond common practices, allowing for design iteration and complete FEM verification. I would recommend PZFlex to any transducer design engineer, not only for the quality of software, but also for the exceptional technical support and customer service.
  • Kyle Morrison, President, Sonic Concepts
The PZFlex software allows us to design and analyse complex transducers for our underwater navigation and communications products in a very short time. If needed, we can easily adapt designs in PZFlex to optimise performance for different operating conditions and environments; an ability that significantly reduces our design cycle time and ensures our clients have confidence in the solutions we provide them with. The professionals at PZFlex are integral to our work, providing both troubleshooting solutions and technical advice that have made it possible to effectively use the design tool in our applications.
  • Erman Uzgur Ph.D., Senior Transducer Design and Acoustic Engineer at Sonardyne
As a small start-up company, we are very conscious of development time. During the proof of concept of our technology, PZFlex has enabled us to rapidly produce, validate and optimise the many iterations of our designs that wouldn’t otherwise be feasible with the other products available on the market. We really hit the ground running with support of the brilliant staff at PZFlex, who have continued to prove their professional and technical quality time and again. If you at all care about getting accurate results at incredible speeds, I couldn’t recommend PZFlex more!
  • Michael Weaver, Cenofex
PZFlex has given us the ability to move beyond the One Dimensional approximations traditionally used to design Tonpilz elements. It gives fantastic insight into the element design and allows optimisation of the elements and housing structures that was previously done by an experimental approach. It gives us confidence in a design much earlier in the design cycle and the transducers designed so far with PZFlex have performed very well, significantly exceeding bandwidth and power handling requirements.
  • Neil Dearing, Technical Director at Neptune Sonar Ltd
I was thrilled about the time PZFlex using to solve my ultrasonic modeling problem. It was beyond my expectation in terms of the speed and the cost-saving of the virtual prototype. What I appreciate most is the great technical support from PZFlex group. That saved me a lot of time and helped me to solve more complex problems.

  • Channa Nageswaran, R&D Team Manager at The Welding Institute
PZFlex has dramatically reduced our prototype design cycles, due to the orders of magnitude reduction in calculation time compared to the competing product we were using previously. In addition, the team at PZFlex have been extremely responsive, creating new calculation add-ons specifically tailored to our requirements, allowing us to model scenarios which were previously not possible. As a result, PZFlex is now a key tool in our design process and will remain so in the future, due to its continually evolving capabilities.
