Submit a report analyzing:
Comparison of the real-time ultrasound data with expected imaging outcomes and clinical applications.
Using the acquired raw RF echo Using the shared ultrasound (US) signals, 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.
Plot and analyze the raw RF echo signals from three different channels, discussing the differences between the acquired echo signals.
Using the B-Mode images, calculate the artery diameter and compare the TOF values of the CCA walls with the results obtained from the raw RF echo signals.
From the acquired B-Mode images, identify frames representing possible systolic and diastolic phases. Calculate the change in artery diameter and discuss the subject's cardiovascular health, referencing relevant literatureCompare the artery diameter for systolic and diastolic phases in terms of artery diameter.
The working freqeuncy 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 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.
There is no limitation for the use of number of frames but use at least two frames to show the artery diameter changes.
