Figure 2

The autoradiography image of supplementary Figure 1 with respectively masks (in black) of: (A) pancreatic tissue, (B) dilated islets and background and (C) islets. (D) is a magnification of (C) and demonstrates the projection of islet activity outside the islets, so called spill-over. (E) visualizes how dilation of the delineated islets (black mask) enables inclusion of all activity originating from the islets, as no spill-over is visible.
