In a 3D image, a mask represents the 'tumor volume.'
How can I easily find its pixel range: [Xmin, Xmax], [Ymin, Ymax], and [Zmin, Zmax]?
I know there is dumb way to do this, but I’m sure MATLAB has a smarter function to achieve this.
Could you suggest an efficient method?
Thanks for your help!

[Y,X,Z]=find(Mask);
S=X+Y+Z;
[~,i]=min(S);
[~,j]=max(S);
[Xmin,Ymin,Zmin, Xmax,Ymax,Zmax] =deal( X(i), Y(i), Z(i), X(j), Y(j), Z(j))
