Experiment details:
Introduction
This experiment involves the use of the Verasonics Vantage 32LE, a sophisticated ultrasound research system, to explore various aspects of ultrasound imaging and data acquisition. Participants will gain hands-on experience with different ultrasound imaging modes, including A-Mode, B-Mode, Colour Doppler, and Power Doppler, while understanding the applications of linear array, curvilinear/convex, and phased array transducers. The experiment will also cover real-time data acquisition using the Verasonics system, focusing on measuring Time-of-Flight values for echoes and analyzing the power spectrum of ultrasound signals in Doppler mode. This comprehensive approach will provide a deeper understanding of both the technical and practical aspects of ultrasound technology.

Set up the Verasonics system for Colour Doppler imaging of the CCA.
Acquire Colour Doppler images, ensuring that the flow is visualized across the vessel.
Use Spectral Doppler to obtain a waveform of the blood flow velocity.
Measure key parameters from the Doppler waveform, such as peak systolic velocity (PSV) and end-diastolic velocity (EDV).
Analyze the flow patterns, and discuss potential clinical implications, such as identifying stenosis or other vascular conditions.
