AIV MAOAC

Please find the data and codes here.

Here, we present artificial intelligence velocimetry (AIV) to quantify the velocity, pressure and stress fields of blood flow for micro-aneurysm-on-a-chip (MAOAC), by integrating the imaging data with underlying physics using physics-informed neural networks.

Directory

• ImageData/: the raw microfluidic images
• HFMdata2D/: data extracted from the images and used for AIV training
• HFMresults/: results after AIV training
• matlab_scripts/: Matlab scripts to visualize the AIV results
• AIV_training.exe: executable program that shows a demo of AIV training

Training AIV

In the command prompt (Windows OS), go to the directory and run

AIV_training.exe

The executable program will take a long time to complete the training, as this is run on CPUs. It will print the log and training loss, and create a .mat file in HFMresults folder after training.
