2. Pre-Lab Quiz

  • Quiz Date: xxxxxx 05.12.2024

  • The quiz will cover the principles of ultrasound technology, imaging modes, and Doppler flow measurement.

  • Review Time-of-Flight measurement, ultrasound transducer functionality, and the basics of Color Doppler and Power Doppler imaging.

...

5. Post-Lab Report

  • Due Date: xxxxxx 11.12.2024

  • Submit a report analyzing:

    • Using the shared ultrasound (US) signals Experiment #7 - Data, calculate the Time-of-Flight (TOF) values for the common carotid artery (CCA) walls and determine the artery diameter for both systolic and diastolic phases.

    • Compare the artery diameter for systolic and diastolic phases in terms of artery diameter.

    • The working freqeuncy frequency of the transducer is 2.25 MHz. So, bandpass filter the signal with suitable cutoff frequencies.

    • While calculating the TOF values, envelope to signal to evaluate the amplitudes.

    • By adjusting the parameters of the peak detection function, isolate the echoes scattered from the anterior and posterior walls.

    • Plot step-by-step the signal processing algorithm:

      • Raw US signals for frames #x, y, z.

      • Filtered US signals for frames #x, y, z.

      • Enveloped US signals for frames #x, y, z.

      • Peak detected US signals for frames #x, y, z.

      • Adjusting Find the anterior and posterior walls after adjusting the peak detection function for frames #x, y, z.

      • TOF calculation for detected anterior and posterior walls.

      • Artery diameter calculation for detected anterior and posterior walls.

      • Show the artery diameter change and describe which frame could be systolic and diastolic phases

      • Describe the used parameters for filter frequencies and peak detecion.

      • Explain the signal processing algorithm.

There is no limitation for the use of number of frames but use at least two frames to show the artery diameter changes.
