I want to do an image processing project on Echocardiography and use MATLAB to semi-automatically diagnose cardiomyopathy, I’d be very grateful if you suggest a technique or any papers on this matter.
The first question to answer is which type of cardiomyopathy are you screening for (i.e. hypertrophic, dialated, restrictive).
Cardiomyopathy is largely a clinical diagnosis that is supported by imaging and other testing. (http://bestpractice.bmj.com/best-practice/monograph/371/diagnosis/step-by-step.html)
Echo measurements can help distinguish between the types of cardiomyopathy and sometimes these measurements provide predictive value of future outcomes. Ejection fraction, ventricular volume, and muscle wall thickness are a few of the measurements taken.
Hopefully some of that information is helpful. I have also linked to a few articles that might be beneficial as well:
