Objective-  To determine the possibility of three-dimensional ultrasonography (3DUS) and measurement of optical nerve sheet by this method. Design- Descriptive study. Animals- 10 mixed normal dogs (5males, 5 females), age 1-1.5 year, and weighting 15±5 kg Procedure- 3D ultrasounds of the eyes were evaluated and the normal optical nerves in 3DUS images were measured using Volouson 730 pro....

This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

abstract       background and aim: dimensional changes of the impression materials after disinfection is a serious problem in dentistry which could fail the treatment. the aim of this study is to determine the effect of three disinfectants:2% deconex,5.25% sodium hypochlorite and nanosil d2 ,on dimensional changes of bayer alginate.       materials and methods: this experimental study was condu...

Background & Aims: The aim of this study was to evaluate the accuracy of Cone-beam Computerized Tomography (CBCT) linear measurements in dry mandibles by comparing them with direct measurements. Methods: Two human dry mandibles were used in this study. Thirteen sites were selected on each mandible. Specimens were scanned by CBCT and linear measurements were made using Planmeca Romexis 2.3.0.R s...

In this article, the authors demonstrate a rapid NMR method to measure a full three-dimensional diffusion tensor. This method is based on a multiple modulation multiple echo sequence and utilizes static and pulsed magnetic field gradients to measure diffusion along multiple directions simultaneously. The pulse sequence was optimized using a well-known linear inversion metric (condition number) ...

OBJECTIVES Wear of total hip replacements has been the focus of many studies. However, frictional effects, such as high loading on intramodular connections or the interface to the bone, as well as friction associated squeaking have recently increased interest about the amount of friction that is generated during daily activities. The aim of this study was thus to establish and validate a three-...

BACKGROUND Pre- and postoperative imaging is important and essential for evaluation of the results of rhinoplasty surgery. Two-dimensional photographs are used routinely for this purpose, but have several disadvantages as opposed to three-dimensional imaging techniques, such as stereophotogrammetry. This study is the first to describe the measurement of rhinoplasty results using stereophotogram...
