From: Ultrafast Volumetric Optoacoustic Imaging of Whole Isolated Beating Mouse Heart

Cross-sectional images of the whole Langendorff-perfused heart. Single plane views were extracted along the x (A–C), y (D–F), and z (G–I) dimension. Features indicated in the side-by-side sketches include the left (LA) and right atria (RA), left (LV) and right ventricles (RV), and interventricular septum.
