VenusX Sizing
Available for research evaluationAI segmentation of the thoracic aorta, user-reviewed centerline and diameters, regional lengths and volumes, structured PDF report.
Science & Evidence
The science behind our models.
LivGemini comes from the H2020 MeDiTATe project on digital twins for aneurysm treatment. Here we separate three things: the methods we published, how the software is verified, and what clinical studies still need to show.
1 · Methods
Published by the team
9 peer-reviewed papers on cardiovascular shape, segmentation, flow modelling and wall biomechanics. They support the approach, not every feature of the current software.
2 · Software verification
Tested against requirements
Each VenusX release is verified under the IEC 62304 life cycle: automated unit, integration and system tests traced to the software requirements.
3 · Clinical studies
In preparation
Studies on the accuracy and clinical usefulness of VenusX are being set up with our research partners. Until results are published, benefits for patients remain research objectives.
