How to extract data from dicom image which shows a echocardiogram?

I'm working on a echocardiogram image. The file type is DICOM with 505 frames, I can view the image using code below, also can view it as a montage:

In = dicominfo('myimagefilename');

[X, map] = dicomread(In);

RW = In.Rows;

Col = In.Columns;

nF = In.NumberOfFrames;

HR = In.HeartRate;

SPP = In.SamplesPerPixel;

Fip = In.FrameIncrementPointer;

for Y = 1:505

 imagesc(X(:,:,:,Y));

 axis off; colormap default  

 hold on;

 pause(0.1)

end

figure (2);

montage (X(:,:,3,1:nF),[]);

This lets me view the image as a it would show up from a heart echo scan (echocardiogram) , How do i extract the heart rate line data also How do I plot the data from each frame showing just the heart rate line?, As the project i'm working on is to analyse the image, I want calculate the beats per minute (even though its given) and to get the max velocity.

Thanks

Have a read here and here. It will greatly improve your chances of getting an answer.

Without a sample of how the images look like, it is impossible to give you sensible hints. Have look at some image processing tutorials, try something yourself and if you are still stuck you're welcome to ask again here.

Good luck, have fun :)
