From: Trabecular architecture in the sciuromorph femoral head: allometry and functional adaptation
Workflow for the selection of the cubic volume of interest (VOI) in the femoral head. Selection of the VOI is shown with a specimen of Tamias rufus (SNMNH, 564127). a Micro-CT coronal slice, 16-bit grayscale image. b Selection of the cubic VOI in the center of the femoral head. The horizontal orange line indicates the central slice which divides the femoral head and the VOI into a proximal and a distal half. The VOI was expanded in three dimensions as much as possible without including cortical bone. c 3D view of the final selection after cropping the image stack. Analysis of trabecular architecture was executed on this substack. Note that these pictures serve as a demonstration for the VOI selection but do not conform with the proper analysis done on this specimen. Scale bars: 1 mm
