MATLAB GUI (GRAPHICAL USER INTERFACE) TASK -

Arterial resistivity index (ARI) is a measure of pulsatile blood flow that indicates the resistance to blood flow through an artery. ARI is calculated with the following formula.

ARI = (v_systole - v_diastole)/v_systole

v_systole is the velocity during contraction and v_diastoleis the velocity during relaxation. The velocity is measured using Doppler ultrasound and one data point is recorded every 3 ms. A Doppler recording is saved in the excel file PatientDoppler.xlsx.

Write a script that does the following:

1. Plot Velocity (cm/s) 'vs' time (ms) with appropriate plot title, x-label, and y-label.

2. Calculate ARI and display to command window. Please put a text indication of what is being displayed.

Note: v_systole is the maximum velocity in the dataset. v_diastoleis the minimum velocity in the dataset.

3. Calculate the instantaneous heart rate from Doppler data as beats per minute and display to the command window. Please put a text indication of what is being displayed.

Note: Use the peaks to calculate heartrate.

HR = 60/(T2 - T1) where T2 and T1 are the points in time where where the maximum peaks occur.

4. Write the ARI and instantaneous heart rate values to a delimited text file called DopplerResults. The delimiter for the text file is a semicolon.

The code should be robust and handle data files of various sizes. Script will be graded for this functionality.

Bonus: If Code 1 is implemented in a GUI, you will get + 10 points added to the grade. GUI must work 100%. There are no partial bonus points. The following is required for the GUI.

ARI and heart rate are displayed to text boxes.

Data is not loaded until a load button is pressed. The GUI uses the file GUIData.txt. It contains two additional columns for a patient name and ID. The name and ID are displayed to two separate text boxes.

Note: The patient first and last name are in the same text box separated by a space. Not a period as seen in the text file.

The plot of the doppler data is on the GUI and displayed as a red solid line with appropriate title and axis labels.

The type of file to output ARI and instantaneous heart rate can be selected from a drop-down menu. The file can be saved as a csv file, or the delimited text file.

The output file is not saved until a save button is pressed.

GUI must be organized in its layout.
