Three-dimensional Display Using Modified Two-dimensionally Aligned Multiple Telecentric Optical Systems.

Simultaneous display of multiple three-dimensional electrophysiological datasets (dot mapping)

Aims Complex ablation procedures are supported by accurate representation of an increasing variety of electrophysiological and imaging data within electroanatomic mapping systems (EMS). This study aims to develop a novel method for representing multiple complementary datasets on a single cardiac chamber model. Validation of the system and its application to both atrial and ventricular arrhythmi...

Stress in three-dimensionally integrated sensor systems

Immersive Planar Display using Roughly Aligned Projectors

When a projector is oblique with respect to a planar display surface, it creates keystoning and the projected image is distorted. We present a rendering technique to display perspectively correct images for a moving user. This allows using roughly aligned projectors and eliminates the need for frequent electro-mechanical adjustments. The rendering process has no additional cost and can be imple...

Three-Dimensional Optical Imaging Using Spectral Constraints

A novel scheme for implementing spectral constraints into a three-dimensional (3-D) image reconstruction model is presented. This approach, based on selecting measurements relating to spatial areas of maximum heterogeneity, makes spectral imaging computationally efficient and feasible in 3-D. ©2006 Optical Society of America OCIS codes: (170.6960) Tomography 1.0 Introduction Optical imaging has...

Three-dimensional volume containing multiple two-dimensional information patterns

We have developed an algorithm for recording multiple gradated two-dimensional projection patterns in a single three-dimensional object. When a single pattern is observed, information from the other patterns can be treated as background noise. The proposed algorithm has two important features: the number of patterns that can be recorded is theoretically infinite and no meaningful information ca...
