Reconstruction of blood vessels from an insufficient number of projections obtained from venography
Autor: Satoru Ohishi, Hideaki Haneishi, Masahiro Yamaguchi, Nagaaki Ohyama, Toshio Honda
Publikováno v: Optics Communications. 102:425-431
The objective of this paper is to develop a method which reconstructs coronary arteries in three dimensions from the small number of projections obtained from venography. Because this reconstruction problem is strongly ill-conditioned, a method, whic

Visualization of 3D volume data using an optical model
Autor: Masahiro Yamaguchi, José Javier Báez-Rojas, Toshio Honda, Satoru Ohishi, Nagaaki Ohyama
Publikováno v: OPT. COMMUN.. 91(No. 1,2):34-40
In this paper we propose a general model for the visualization of the 3D volume data, called optical model (OM). We present the model in its most general form, and a particular case is used for the display of computed tomography (CT) data. The optica

Three-dimensional reconstruction from cone beam projections
Autor: Toshio Honda, Masahiro Yamaguchi, Nagaaki Ohyama, Satoru Ohishi
Publikováno v: Medical Imaging V: Image Physics.
Three-dimensional Computed Tomography (CT) with cone-beam geometry will take the place of a conventional CT because 3-D CT is superior to conventional CTs in terms of both data acquisition time and spatial resolution, particularly along the rotation

High-speed surface display through hybrid processing
Autor: Jumpei Tsujiuchi, Satoru Ohishi, Nagaaki Ohyama, Toshio Honda, Masahiro Yamaguchi
Publikováno v: Optics Letters. 15:565
We propose a high-speed surface reconstruction from three-dimensional data through optical–digital hybrid processing. Surface images are currently reconstructed through digital processing, which takes a long time mainly because of the rotation and
