ROI coding of volumetric medical images with application to visualisation [PDF]

open access: yes, 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.

Persistent homology for 3D reconstruction evaluation [PDF]

open access: yes, 2012
Space or voxel carving is a non-invasive technique that is used to produce a 3D volume and can be used in particular for the reconstruction of a 3D human model from images captured from a set of cameras placed around the subject.

Approximate Bayesian framework for 3D reconstruction in a volumetric PIV/PTV measurement

open access: yes14th International Symposium on Particle Image Velocimetry, 2021
Non-invasive flow velocity measurement techniques like volumetric Particle Image Velocimetry (PIV) (Elsinga et al., 2006; Adrian and Westerweel, 2011) and Particle Tracking Velocimetry (PTV) (Maas, Gruen and Papantoniou, 1993) use multi-camera ...

Creating high-resolution 3D cranial implant geometry using deep learning techniques

open access: yesFrontiers in Bioengineering and Biotechnology, 2023
Creating a personalized implant for cranioplasty can be costly and aesthetically challenging, particularly for comminuted fractures that affect a wide area. Despite significant advances in deep learning techniques for 2D image completion, generating a 3D

Volumetric Computed Tomography Reconstruction, Rapid Prototyping and 3D Printing of Opossum Head ( Didelphis albiventris ) [PDF]

open access: yesInternational 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 ...

Assessment of imaging models for volumetric tomography of fluid flows [PDF]

open access: yes, 2022
Volumetric tomography is a powerful tool that employs 2D projections to reconstruct unknown physical quantities in 3D fluid flows. A mathematical model of the imaging process is required to recover the desired volumetric fields.
