Objective: The aim of this study was to compare the quality of images obtained with 3D T2-weighted sequence with the quality of conventional 2D T2-weighted images. Subjects and Methods: Thirty consecutively registered patients (average age, 55 year; age range 32-79 years) underwent imaging at 3.0 T with a 6-element body array coil. All imaging was performed with three T2-weighted images: 3D axi...

Purpose : To compare the enhancement pattern of normal facial nerves on 3D-FLAIR and 3D-T1-FFE-F) sequences at 3.0 T MR units. Materials and Methods: We assessed 20 consecutive subjects without a history of facial nerve abnormalities who underwent temporal bone MRI with contrast enhancement between January 2008 and March 2009. Two neuroradiologists independently reviewed pre-/post-enhanced 3D-T...

Spatial 3D images created by high-definition computational holography are actually demonstrated. The demonstrated 3D images are static images at this stage. However, these presage the great future of 3D displays beyond the Super Hi-Vision because of its strong sensation of depth, which never has been caused by conventional 3D systems.

Confocal laser scanning microscope (CLSM) can obtain multichannel 3D images from biological tissues for analysis of tissue structures, where each channel results from a particular fluorescent label. The visualization of the multi-channel 3D confocal microscope images is required for qualitative, interactive, and even quantitative analysis of the structures of the studied tissues. Despite the av...

BACKGROUND & OBJECTIVES With improvement in the early diagnosis of breast cancer, breast conserving therapy (BCT) is being increasingly used. Precise preoperative evaluation of the incision margin is, therefore, very important. Utilizing three dimentional (3D) images in a preoperative evaluation for breast conserving surgery has considerable significance, but the currently 3D CT scan reconstruc...

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...

Axially distributed image sensing (ADS) technique is capable of capturing 3D objects and reconstructing high-resolution slice plane images for 3D objects. In this paper, we propose a computational method for depth extraction of 3D objects using ADS. In the proposed method, the high-resolution elemental images are recorded by simply moving the camera along the optical axis and the recorded eleme...

This paper proposes an automatic method for registering images from different sensors, particularly 2D optical sensors and 3D range sensors, without any assumption about initial alignment. Many existing methods try to reconstruct 3D points from 2D image sequences, and then match 3D primitives from both sides. The availability of appropriate multiple images associated with 3D range data, the wel...

segmentation and three‑dimensional (3d) visualization of teeth in dental computerized tomography (ct) images are of dentists’ requirements for both abnormalities diagnosis and the treatments such as dental implant and orthodontic planning. on the other hand, dental ct image segmentation is a difficult process because of the specific characteristics of the tooth’s structure. this paper presents ...
