background : improvement of facial beauty is a major reason why patients with dentofacial problems opt for orthognathic surgery. people are eventually judged by their facial appearance by themselves, their friends & family and even surgeons. with the recent developments in technology, we now have a 3d structure that can build and analyze 3d images before & after surgery and review the extent of...
background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures. methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...
purpose:dental shade guides are commonly used for color determination and should be disinfected and sterilized. the purpose of this study was to evaluate the color change of vita 3d master shade tabs after disinfection and sterilization. material and methods:overall, 98 samples (shade tabs) were randomly selected from 14 new, unused vita 3d sets, including the following shades: 2m1, 3l1.5, 3m1,...
Background: It is of clinical importance to display the vasculature of transplanted kidney in three-dimensional (3D) and in non-invasive way. 3D color Doppler ultrasonographic imaging (3D-CDUI) is a non-invasive technique to display the 3D vasculature of living organs. Objective: Probe into characteristics of 3D vasculature of living transplanted kidney by 3D-CDUI, and evaluate the clinical val...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
This article presents anaglyph method for generating tridimensional multimedia content. We will discuss how to acquire 2D image and how to convert 2D images to 3D image by keeping the original image accuracy. In this paper we show some problems regarding the 3D effect construction. This article proposes an algorithm to solve those issues. The algorithm was implemented by using Matlab environmen...
While 3D visualization technology is still in its infancy, hardware capabilities have progressed to the point where useful, practical work can be done. However, there exists significant barriers to using 3D visualization, primarily in usability and interfaces. 3D visualization is closely linked with the realization of depth or the distance between the objects along the 3 mutually perpendicular ...
