TL;DR: The feasibility of 3D NIR fluorescence tomography imaging is demonstrated by employing DOI-PET detectors in computer simulations and it is confirmed that the reconstructed images from low-resolution detectors are the same as those from high- resolution detectors.
Journal ArticleDOI
Optical Interpolation of Volume Data Using Pseudo Color and an Electro-Optical-Hybrid-System
TL;DR: The visualization of a volumetric array of computed tomography data is achieved using the optical interpolation technique in combination with the optical model and the electro-optical-hybrid-system.
Journal ArticleDOI
Information retrieval method considering the individual differences and its opto-electronic implementation
TL;DR: In the proposed method, the history of the retrieval process is used to estimate the degree of relevance among the keywords, and an opto-electronic implementation of the proposed retrieval system is presented to realize a rapid retrieval.
