4D RV-Function

Comprehensive evaluation of right ventricular function, the right way

The right ventricular quantification tool for clinical routine work, pulmonary hypertension
and right sided heart failure.
4D RV-FUNCTION* allows complete evaluation of the right ventricle and combines 3D and 2D
values including EDV, EDVi, ESV, ESVi, EF and SV, RVLS, TAPSE and FAC. 4D RV-FUNCTION helps to overcome the RV complexity by calculating standard values based on a 3D surface model. A detailed and easy to follow workflow allows users to adapt the proposed contour quick and easy.


Overcome the challenges of right ventricle geometry by defining 2D landmarks to construct a 3D surface model.


Automated 2D measurements with every 3D analysis

  • 3D measurement results: RV EDV, EDVi, ESV, ESVi, EF, SV
  • Guideline conform 2D measurement results: TAPSE, Distances, FAC
  • Additional strain values: RVLS free wall and septum

The two minutes tool for your right ventricle analysis

  • Only a few landmarks away from your contour proposals
  • Automatic contour proposal - no laborious contour drawing
  • Quick and reproducible results

Increase your diagnostic confidence by visualizing the complex RV shape in 3D

  • Calculating right ventricular data based on a complex 3D surface model
  • Validated model of the right ventricle
  • Display your model in combination with 2D planes for a better control

Customer Experiences


... We have already published our research showing the 3D evaluation of the RV function is very close to that using MRI. And TOMTEC is the only independent vendor offering a software solution for 3D analysis.

“Since many years, the challenging task of analyzing the RV from 3D data sets relies exclusively on TOMTEC software.

The new automatic RV-FUNCTION algorithm really makes this task easier. Working with first-time users testing both the old and the new software tools, you can feel that the new software is easier to learn and faster to use. Now, some of the latest 3D ultrasound systems come equipped with the new RV TOMTEC software on board.

Our department at the University of Padua is a referral center for many patients with suspected or known RV pathology, including pulmonary hypertension, ARVC, GUCH and athletes. After having tested its accuracy in real-life patients against CMR, we have adopted the RV-FUNCTION software as the standard tool for measuring RV volumes and ejection fraction for both patient care and research purposes.”
