Book cover for PHD thesis (Artificial inteligence in Cardiology)

This is what a business in Netherlands was looking for in their book cover design

I'm looking for a cover book for my PhD thesis "Development and Validation of Machine Learning Models in Cardiology" which is, essentially, artificial intelligence applied to cardiology.
I'm looking for something relatively simple but original, elegant and with personality.
I'm not looking for a cover with a bunch of figures from image platforms (I'm expecting something made by yourself). Also, no robots or matrix (movie). It doesn't have to contain (or be) necessarily a heart (be creative).

The title of the thesis can be part of the design. The back cover doesn't have any texts (but might have illustrations or parts of it as well, if suitable).

Following some machine learning keywords:
support vector machine; decision trees, random forest; neural networks; deep learning.
