How can I plot the saggital image on xz refence plane when I used isonormals to plot an 3D recontruction?
set ( handles.axes2, 'NextPlot', 'Replace')
imagesc ( imagen_rotada_a_graficar)
axis image
colormap gray
Ds = smooth3(mascaracontorno3D2);
fv = isosurface(Ds,0);
hiso = patch(fv, 'FaceColor', [0.6350 0.0780 0.1840], 'Edgecolor', 'none');
isonormals(Ds, hiso)
Ds1 = smooth3(mascaracontorno3D);
axis tight
camlight
camlight(-80,-10)
lighting gouraud
view(3)
daspect([1,1,1])

Hi José,
You can plot this by utlizing the volume data you used for creating the 3D plot. Extract the sagittal slice from your volume data. The sagittal slice is typically taken along the Y-axis, meaning you will fix the Y value and vary X and Z. You can then use the 'imagesc' or 'imshow' functions to plot this slice in the XZ plane. Please refer the following documentation for more information:
Hope this helps!
