Abstract

Objective

We aim to simulate the uterine electrical activity at the myometrium level and at the skin level where it can be recorded non-invasively.

Material and methods

We use 2D models both at the myometrium scale and for the volume conductor. The multi-scale model has been implemented in Python, as a complete package including the needed tools. To speedup the slowest step, we integrated parallel execution.

Results

We obtain realistic simulations of EHG signals as recorded by an electrode array placed on the woman abdomen.

Conclusion

These simulations are still generic, the next problem to address will be the identification of the model’s parameters to obtain patient-specific simulations.
