Our solutions

Thousands of Virtual Patients

Select your virtual patient population from our extensive database of humans and animals based on real CT scans. Choose based on disease, age, sex, ethnicity, ejection fraction, and your anatomical parameters. Perform virtual implant fitting, interactive measurements, and collision detection.

3D measurements ensure high accuracy in contrast to measuring on 2D CT scan slices. Our expertise allows for complex measurements, including cardiovascular strain and loading conditions analysis.

Main features:

  • Virtual patient cohort tailored for you
  • Advanced 3D visualization and interactive implantation
  • Accurate & reproducable 3D measurements and extensive statistics

Advanced Statistical Shape Models

Select your chosen patient group and create the average patient anatomy automatically. Investigate different age groups, ethnicities, and only female or male patients. Combine the anatomical variations and investigate their influence on your design.

Identify worst-case anatomies and improve your device coverage. Extend the indications of use to treat the maximum number of patients resulting in major financial benefits.

Main features:

  • Worst and edge-case anatomies
  • Average patient anatomy
  • Extensive statistics of demographics & measurements

Advanced Anatomical Simulations

Simulate your implant or product family in the entire virtual target population to investigate how these body variations may affect the performance and safety of your device. In addition, identify the potential for design optimization and material selection by conducting parameter analyses.

We offer a device and use case tailored customized simulation environment based on your use case and product phase.  Get access to an easy to use, intuitive solution where no expert simulation knowledge is needed.

Main features:

  • Validated ISO benchtop test simulations
  • Validated in-human implant simulations
  • You control the simulations, we take care of all difficulties

Regulatory Services & Consultation

Compared to conventional in vivo and in vitro testing, in silico trials of implants are more time and cost efficient. We provide digital evidence of your anatomy, statistical and simulation results to support your technical documentation with FDA-compliant reporting (FDA 1807 & ASME V&V40).​

Ask our regulatory experts to establish your virtual testing plan connected to your physical testing. Learn about the new FDA guidance documents and ASME standards for Computational Modeling and Simulation. Our experts will highlight how you can apply them and streamline your regulatory process.

Main features:

  • Regulatory path with a virtual testing plan
  • Compliance with all regulatory bodies
  • Validated virtual evidence report


We develop our digital twins from real imaging data.

You can access our database of thousands of human and animal 3D models segmented from real CT and MRI scans. Whole heart and full thorax models are available including every organ.

Physiological data brings the patients “alive” and enable anatomical simulations. Tissue material models (elasticity parameters), blood flow properties (pressure & velocity) and electrocardiogram (ECG) data expand our anatomical database.

Choose different parameters to select your digital twin:


  • Heart failure
  • Tricuspid valve insufficiency
  • Aortic stenosis
  • Mitral valve insufficiency
  • and more…

Location or ethnicity:

  • Europe
  • North America
  • Asia
  • and more…

Age group:

  • Pediatric patients
  • Adult patients
  • Geriatric patients

Animal breeds:

  • Sheep (Milksheep, Île-de-France, Swifter)
  • Pig (Domestic, LeWe-Minipig)
  • Calf (Jersey)
  • and more…

The data and the analysis that Virtonomy has provided during our partnership are key tools for strengthening and expanding our knowledge basis of the anatomical boundary conditions.
