NADH-d evaluation. Example of full thickness (entire kidney) tissue section stained with NADH-d (top). Treatment location was from the left (Red arrow). Non-treated parenchyma stains purple/blue (bottom left); lesion is identified by non-staining (black arrow and bottom right). This tissue was treated at a duty cycle of 50% at a fixed derated spatial peak pulse averaged intensity of 9,320 W/cm2.
