General information This simulation data belongs to the article: Retrieving pulsatility in ultrasound localization microscopy DOI: 10.1109/OJUFFC.2022.3221354 This information is also available in README.txt, included in this repository. Code availability The scripts that should be used to process this data can be found at: https://github.com/qnano/ulm-pulsatility 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.
