Mounting of a left porcine lung for imaging. Left: The right main bronchus is sealed off by a clamp (green) and fixed to the lid of the vacuum chamber with zip ties. The tube is securely fixed into the trachea and connected to the inlet in the lid. Middle: The left porcine lung inflated inside the vacuum chamber at −30 mbar. Right: Point of view from \(\hbox {G}_2\) of the symmetric TLGI into the vacuum chamber. (A) Lateral basal segment of the inflated left porcine lung. (B) A piece of non-inflated porcine lung tissue. (C), (D), (E) Eppendorf tubes containing PMMA spheres of 425–500 \(\upmu \hbox {m}\), 180–212 \(\upmu \hbox {m}\) and 20–27 \(\upmu \hbox {m}\) diameter, respectively. (F) A M4 steel screw (\({4}\,\hbox {mm}\) in diameter) as reference marker.
