Articulated Planar Reformation for Change Visualization in Small Animal Imaging

The analysis of multi-timepoint whole-body small animal CT data is greatly complicated by the varying posture of the subject at different timepoints. Due to these variations, correctly relating and comparing corresponding regions of interest is challenging. In addition, occlusion may prevent effective visualization of these regions of interest....

Articulated Whole-Body Atlases for Small Animal Image Analysis: Construction and Applications

Purpose Using three publicly available small-animal atlases (Sprague–Dawley rat, MOBY, and Digimouse), we built three articulated atlases and present several applications in the scope of molecular imaging. Procedures Major bones/bone groups were manually segmented for each atlas skeleton. Then, a kinematic model for each atlas was built: each...

Atlas-driven scan planning for high-resolution Micro-SPECT data acquisition based on multi-view photographs: A pilot study

Highly focused Micro-SPECT scanners enable the acquisition of functional small animal data with very high-resolution. To acquire a maximum of emitted photons from a specific structure of interest and at the same time minimize the required acquisition time, typically only a small subvolume of the animal is scanned that contains the organs of...
