R = 2:2:10 ;
th = linspace(0,2*pi) ;
figure
hold on
for i = 1:length(R)
x = R(i)*cos(th) ;
y = R(i)*sin(th) ;

I have no idea what you want to do. All professional programmers put comments into their code. Where are yours? Explain every section or line of your code up until the plotting part.

You cannot reliably recreate the roi given just the subimage and comparing it to 0, as interior pixels could be 0.
You could, it is true, take the subimage and fit a circle to it to recreate the roi.
But if you are going to need the roi later, just record the mask variables as well, it saves a lot of trouble.
