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:

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:

RAW_tracks.mat 
Track_r1_illustration.mat
Track_r2_illustration.mat
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.
