Digital Holography and Three-Dimensional Imaging, 2011
A computational reconstruction technique with variable viewing angles is proposed, which simulates non-parallel reconstuction planes. Experimental results support the validity that the image is reconstructed only at the exact angular position.

Applied Optics, 2009
In this paper, we propose a novel computational integral-imaging reconstruction (CIIR)-based three-dimensional (3-D) image correlator system for the recognition of 3-D volumetric objects by employing a 3-D reference object. That is, a number of plane object images (POIs) computationally reconstructed from the 3-D reference object are used for the 3-D ...

A pre-recognition SART algorithm for the volumetric reconstruction of the light field PIV
Optics and Lasers in Engineering, 2021As a novel volumetric velocimetry technique, the light field particle image velocimetry (LF-PIV) based on a single light field camera benefits from its single perspective configuration and has great potential applications in the space-constraint flow ...

Volumetric reconstruction and stereotactic computer assisted resection in intracerebral lesions
Acta Neurochirurgica, 1996Since 1990 112 patients have undergone stereotactic resection of intra-axial tumoural lesions with volumetric reconstruction, using the Kelly-Goerss system. Stereotactic integration of CT, angiographic and particularly MRI information, together with three-dimensional information of the lesion, provide an innovative evaluation of the most appropriate ...

High‐Quality Volumetric Reconstruction on Optimal Lattices for Computed Tomography
Computer Graphics Forum, 2009AbstractWithin the context of emission tomography, we study volumetric reconstruction methods based on the Expectation Maximization (EM) algorithm. We show, for the first time, the equivalence of the standard implementation of the EM‐based reconstruction with an implementation based on hardware‐accelerated volume rendering for nearest‐neighbor (NN ...

Parallel computation for rapid reconstruction of volumetric ultrasonic images
IEEE 1992 Ultrasonics Symposium Proceedings, 2003A massively parallel computer, the Princeton Engine (PE), is applied to the task of volumetric ultrasound image reconstruction. Results are compared with those obtained on a conventional, sequential computer (a Sun SparcStation 1). The PE reduces reconstruction times by a factor of approximately 500 over the Sun, making possible the creation of a ...
