Bonjour à tous j'ai en entrée 25 images IRM(dicom).
je metsen un point fixe (x,y) et je garde l'emplacement de ce pixel pour les autres images.
je veux tracer la courbe de progression de ce pixel. comment programmer ça?
Hello everyone, I have 25 MRI images (dicom) as input. I put a fixed point (x, y) and I keep the location of this pixel for the other images. I want to plot the progression curve of this pixel. how to program that?

You can either use imshow (use the axes object handle), or you can set the CData property of an image object (which is the output of the imshow function).

%load an example image
S=load('mri');
I=squeeze(S.D);
x=randi(size(I,1));y=randi(size(I,2));
intensity=squeeze(I(x,y,:));
plot(intensity)

You should put in your own image and coordinates. It can happen that an x-y-combination is 0 for all z values. This will happen around the edge. Unfortunately, this example image is about half edge, so if you want to use random coordinates, you will get this line about half the time.
