This paper explores new methods to visualize and fuse multi-2D bioluminescence imaging (BLI) data with structural imaging modalities such as micro CT and MR. A geometric, back-projection-based 3D reconstruction for superficial lesions from multi-2D BLI data is presented, enabling a coarse estimate of the 3D source envelopes from the multi-2D BLI data. Also, an intuitive 3D landmark selection is...

PURPOSE: Validation of image registration algorithms is frequently accomplished by the visual inspection of the resulting linear or deformable transformation due to the lack of ground truth information. Visualization of transformations produced by image registration algorithms during image-guided interventions allows for a clinician to evaluate the accuracy of the result transformation. Softwar...

Distributed systems technologies supporting 3D visualization and social collaboration will be increasing in frequency and type over time. An emerging type of head-mounted display referred to as the head-mounted projection display (HMPD) was recently developed that only requires ultralight optics (i.e., less than 8 g per eye) that enables immersive multiuser, mobile augmented reality 3D visualiz...

Networked technologies supporting distributed 3D visualization and social collaboration will be increasing in frequency and type over time. An emerging type of headmounted display referred to as the Head-Mounted Projection Display (HMPD) was recently developed to only require ultra-light optics (i.e. less than 8 g per eye) that enables immersive multi-user, mobile augmented reality 3D visualiza...

3D visualization techniques enable an intuitive mediation of complex, space related facts. Civic participation in community landscape planning or visual simulations of landscapes could benefit from emerging computer graphics technologies. However, interactive visualization tools matching the special needs of landscape planning only exist in their beginnings. In 2000, the Centre for Agricultural...

A not negligible number of information visualization techniques uses 3D-geometry to visualize data and structures. Thereby, constantly growing data volumes influence the final visual representation and often result in the occlusion of certain items. Therefore, different approaches have been developed that mainly manipulate item positions to uncover specific items of interest or otherwise use fi...

The establishment and visualization of large, reality-based 3D terrain and city models has received significant attention over the last few years. However, the recent progress in 3D data capturing generated very huge and complexe 3D models. This poster presents tools for geo-visualization based on multi-resolution representations of different objects (terrain, buildings, vegetation, etc). Thank...

INTRODUCTION We compared the impact of two-dimensional (2D) versus three-dimensional (3D) visualization on both objective and subjective measures of laparoscopic performance using the validated Fundamentals of Laparoscopic Surgery (FLS) skill set. SUBJECTS AND METHODS Thirty-three individuals with varying laparoscopic experience completed three essential drills from the FLS skill set (peg tra...

BACKGROUND Three-dimensional (3D) visualization is thought to improve the anatomical understanding of clinicians, thus improving patient safety. CASE PRESENTATION A 58-year-old male was admitted to our hospital in April 2007 with a suspected metastasis of a sigmoid cancer in the Couinaud segment (CS) 7. The anatomical situation of this patient was analyzed using both a CT scan and 3D images. ...

3D visualization for Content-Based Images Retrieval (CBIR) eases integration of searching and browsing images in a large image database. While many researchers proposed visualization system for CBIR, most approaches display images based on a fixed set of image features. However, not all features are always equally important for users. Moreover, in most systems, all images in the database are di...
