Reproducing the Article Figures

This pages provides details of how to reproduce the figures in the article describing the pulse wave database.

Requirements

It is assumed that the previous steps outlined in Reproducing the Pulse Wave Database have been carried out, and that figures have been generated by running the following scripts:

calculate_pwdb_input_parameters.m (as described here)
analyse_pwdb.m
ppamp_case_study.m, asi_case_study.m and co_case_study.m (as described here)

Figures

Instructions are now provided on how to reproduce each individual figure. EPS figures were used in the article.

Figure 1: The 1D model of pulse wave propagation and simulated pulse waves

This figure contains the following plots, which are produced by analyse_pwdb.m and stored in the .../pwdb_#/analysis/figures/ directory:

Aortic inflow: waves_Q_AorticRoot_baseline
Simulated waves at carotid artery: waves_Q_Carotid_baseline, waves_A_Carotid_baseline, waves_U_Carotid_baseline, waves_P_Carotid_baseline, waves_PPG_Neck_baseline.

Figure 2: A summary of the literature review findings

This figure contains plots produced by calculate_pwdb_input_parameters.m, which are stored in the directory specified by up.savefolder within the setup_up function. The following plots were used:

Changes in parameters with age: the changes_w_age_... plots were used to create the sub-plots of Heart Rate to Diastolic Blood Pressure.
PWV vs Diameter: Wave_speeds (note that to generate this plot the database configuration specified in the setup_up function of calculate_pwdb_input_parameters.m should be set to 'baseline_subjects_at_each_age').

Figure 3: PWs for the 25-year old subject at the carotid artery and the radial artery

This figure contains two plots which are generated by analyse_pwdb.m and stored in the .../pwdb_#/analysis/figures/ directory:

waves_initial_variations_Neck - carotid artery
waves_initial_variations_Wrist - radial artery

Note that these figures were generated from a mini-database obtained using the 'initial_simulations' database configuration specified in calculate_pwdb_input_parameters.m.

Figure 4: Pulse wave (PW) analysis, illustrated for a radial pressure PW

The following figures were used, generated by analyse_pwdb.m and stored in the .../pwdb_#/analysis/figures/ directory:

demo_P_Radial_fid_pts
demo_P_Radial_cv_inds

Figure 5: The pressure, flow velocity, luminal area and photoplethysmogram pulse waves at common measurements sites

The following figures were used, generated by analyse_pwdb.m and stored in the .../pwdb_#/analysis/figures/ directory:

baseline_waves_fig_a
baseline_waves_fig_b

Figure 6:

Tables

Table 1: The haemodynamic characteristics of the PW database for all virtual subjects

The data used in this table is generated by analyse_pwdb.m and stored in the characteristics_table_csv file in the .../pwdb_#/analysis/tables/ directory.
