VAN-GAN (Vessel Segmentation Generative Adversarial Network) Sweeney, P.W. et al. (2024)

''' Synthetic Paired Dataset ''' The raw data for physic-driven photoacoustic (PA) simulations and the synthetic vascular segmentation masks are to be placed in 'raw_data/PA_Simulations' and 'raw_data/Synthetic_Segmentations', respectively.

PA Simulations are split across 5 zip files 'PA_Simulations_*'. Synthetic segmentations are in a single zip. Each dataset consist of 459 tiff stacks.

Raw image size: 512 x 512 x 140 (X x Y x Z) with isotropic voxels with 20 um width/height/depth (for all images in datasets).

''' Preprocessing ''' Preprocessing steps are available in the VAN-GAN code. If the option is selected to saved filtered data, tiff stacks will be saved into their train/test/val subfolder in 'filtered'.

Data for VAN-GAN is stored as numpy files in train/test/val folders in the main directory.

A or B indicates whether the files belong to the PA simulation or segmentation mask dataset.

Example outputs are provide in 'Example_Outputs'. Here, data was saved following training of the 200th epoch. The provided tiff stacks are either a predicted segmentation mask or a fake PA simulation.
