Data description

The simulation data in this repository, is contained in several .zip files:

• DataSetFig3.zip: This dataset contains the simulation data needed to reproduce Fig. 3 of the article.
• DataSetR1.zip: This dataset contains the simulation data corresponding to the lateral vessel location R1. It is needed to reproduce Fig 4 and Fig. 6b. 
• DataSetR2.zip: This dataset contains the simulation data corresponding to the lateral vessel location R2. It is needed to reproduce Fig 4 and Fig. 6b. 
• DataSetR3.zip: This dataset contains the simulation data corresponding to the lateral vessel location R3. It is needed to reproduce Fig 4 and Fig. 6b. 

The .zip folders contain the following:

• LOTUS_INPUT: This folder contains the input simulated ultrasound images, of which the file names are parametrized as:

1. chunk***.mat:     Data set containing IQ variable of size 180x240x1000, containing 1000 B-mode images of dimension 9mmx12mm

• ULM_results: This folder is initially empty. Results of running the scripts will be stored in this folder.
• PAR.mat: Parameters with which the ultrasound images are simulated. See scripts for further details.
• TOTAL_MB.mat: Contains the variable MB_loc_conc that describes the simulated (ground truth) location of the MBs at each frame (z, x) [mm].
• Saved MB tracks used for visualization. One of the following options:

1. RAW_tracks.mat 
2. Track_r1_illustration.mat
3. Track_r2_illustration.mat
4. Track_r3_illustration.mat

• GT_theta.mat: Ground truth orientation of the simulated vessels
• velAv.mat: Average velocity in the simulated vessels during the simulation.
