ROI coding of volumetric medical images with application to visualisation [PDF]
, 2003 This paper presents region of interest (ROI) coding of volumetric medical images with the region itself being three dimensional. An extension to 3D-SPIHT which allows 3D ROI coding is proposed.

Volumetric Computed Tomography Reconstruction, Rapid Prototyping and 3D Printing of Opossum Head ( Didelphis albiventris ) [PDF]
International Journal of Morphology, 2019 SUMMARY: Natural anatomical pieces of wild animals are rare and teachers seek alternatives in satisfactory quantity and quality to inform their students. This article aims to describe the use of multiplanar reconstructions and 3D volume rendering computed tomography (CT) images, rapid prototyping and 3D printing of opossum head to create a biomodel to ...
