Patient specific models for decision support in diagnosis

Thanks to diversity of technologies, our products can be used for solving a wide variaty of medical problems.
These are few applications:

  • Coronary artery test case

dynaROM™ allows one to reproduce simulations of arterial systems.

The average velocity is imposed at the inlet of the coronary. The velocity profile in red was used to build the dynaROM™ model. The velocity profile in blue was used for validation.

One can see a good agreement between dynaROM™ predictions and the results obtained by Fluent computations.

 

 

  • General Electric incubator

Using dynaROM™ we can command and control nonlinear systems, in this case a General Electric incubator.
dynaROM™’s input is the Thermal power injected in the system and the velocity of the fan. The output is the temperature measured by 6 sensors.

Learning excitations:

Validation excitations:

Validation results: dynaROM™ Model VS reference data (last sensor):

 

  • Classification ethnicit

deepROM® is a static neural network factory, it can be used for regression or classification.
In this case, combined with a linear compression, deepROM® was used to classify the ethnicity of a set of people using their genome.

It is clear from the figure that our method gives better results. In fact, the failure rate of deepROM® is 4,348%, it is almost half the state of the art’s rate of failure.
