The paper presents approaches to the survey and use of such unique natural formations as lunar lava tunnels. The most important applied technology pro-posed for use at the stages of design, construction and operation of lunar bases is laser scanning. The capabilities of existing lidar systems allow obtaining spa-tial data on objects and formations on the surface of other planets with high accuracy and efficiency. The issues of practical application of mobile and sta-tionary scanning laser studies of lunar lava tunnels are considered.

Abstract The hippocampus plays an important role in learning and memory, requiring high-neuronal oxygenation. Understanding the relationship between blood flow and vascular structure – and how it changes with ageing – is physiologically and anatomically relevant. Ultrafast Doppler (µDoppler) and Scanning Laser Confocal Microscopy (SLCM) are powerful imaging modalities that can measure in-vivo Cerebral Blood Volume (CBV) and ex-vivo vascular structure, respectively. Here, we apply both imaging modalities to a cross-sectional and longitudinal study of hippocampi vasculature in wild-type mice brains. We introduce a segmentation of CBV distribution obtained from µDoppler and show that this mice-independent and mesoscopic measurement is correlated with the number of vessels and Vessel Volume Fraction (VVF) distributions obtained from SLCM – e.g., high CBV relates to fewer number of vessels but with large VVF. Moreover, we find significant changes in CBV distribution and vasculature due to ageing (5 vs. 21 month-old mice), highlighting the sensitivity of our approach. Overall, we are able to associate CBV with vascular structure – and track its longitudinal changes – at the artery-vein, venules, arteriole, and capillary levels. We believe that this correlative approach can be a powerful tool for studying other acute (e.g., brain injuries), progressive (e.g., neurodegeneration) or induced pathological changes.
