Simulated VFI ultrasound data for a parabolic flow profileThe RF data was obtained from simulating the flow in a straigth tube with a parabolic velocity profile by using the Field II program. The data was then beamformed as described in [1], so they are usable for vector flow imaging using the Transverse Oscillation (TO) method [1,2]. The data for the simulation are given below:
The RF data can be obtained from the zip archives (512 MBytes): Each of the files contains two variables: TO_data and axial_data. TO_data contains the transverse oscillation data used for the tranverse velocity component. It is a three-dimensional structure where the first index is depth, the second is sample number in the transverse signal, and the third index is the emission number. axial_data contains the RF data in the axial direction and is a two-dimensional matrix, where the first index is depth and the second is emission number. Each variable contains data fro 129 emissions. The file is called TO_data_seq_01.mat, where each file contains 129 emissions. There are 20 of these files of 01 to 20. The various variables used in the simulation and beamforming can be found in the file bft3_directional_flow_parameters.mat References
