The work reported in this paper aimed at developing and testing an automated method to calculate the biodistribution of a specific PET tracer in mouse brain PET/CT images using an MRI-based 3D digital atlas. Surface-based registration strategy and affine transformation estimation were considered. Such an approach allowed overcoming the lack of anatomical information in the inner regions of PET/CT...
Potential Well Space Embedding (PWSE) has been shown to be an effective global method to recognize segmented objects in range data. Here Local PWSE is proposed as an extension of PWSE. LPWSE features are generated by iterating ICP to the local minima of a multiscale registration model at each point. The locations of the local minima are then used to generate feature vectors, which can be matched against...
