Several software programs have been designed for outcome prediction of orthodontic and surgical treatments. This study aimed to review the accuracy and characteristics of cephalometric software programs for outcome prediction of orthognathic surgeries. This study reviewed studies that compared cephalometric software programs in terms of accuracy and characteristics for outcome prediction of o...

patients and methods in 382 subjects admitted in the emergency department (ed), we evaluated maximal (volmax) and minimal (volmin) la volumes and la emptying fraction (la-ef), from rt-3d images, with a semiautomated border detection program. a follow-up was performed in order to evaluate all-cause mortality and new hospital admission for cardiovascular events. objectives aims of this study were...

BACKGROUND/OBJECTIVE Judgement of nasolabial aesthetics in cleft lip and palate (CLP) is a vital component of assessment of treatment outcome. It is usually performed based on two-dimensional (2D) facial photographs. An increasing use of three-dimensional (3D) imaging warrants an assessment if 3D images can substitute 2D photographs during aesthetic evaluation. The aim of this study was to comp...

left atrial (la) distension has been demonstrated to be linked with aortic stiffness in different patient populations. three-dimensional (3d) speckle-tracking echocardiography (ste) seems to be a promising tool for volumetric and functional evaluation of the la. the aim of the present study was to determine whether correlations exist between 3dste-derived la volume-based and strain parameter...

Our objective was to determine the accuracy of three dimensional (3D) ultrasonography in the differentiation of ovarian tumours. Women (n = 20) with ovarian tumours (13 benign and seven malignant) were first examined using two-dimensional (2D) ultrasonography and were then evaluated with three-dimensional (3D) ultrasonography. All patients underwent surgery within 7 days of 2D and 3D ultrasonog...

BACKGROUND To compare 3-dimensional gadolinium-enhanced elliptic centric-ordered (3D GEC) magnetic resonance venography (MRV) with traditional 2-dimensional time-of-flight (2D TOF) MRV for imaging of the intracranial venous system. METHODS Fifty-three patients underwent 2D and 3D MRV, whereby venous structures were evaluated by 2 neuroradiologists. RESULTS Of the 53 patients, 10 were diagno...

Prior studies on converting three-dimensional (3D) range data into regular two-dimensional (2D) color images using virtual fringe projection techniques showed great promise for 3D range data compression, yet they require resampling the raw scanned data. Due to this resampling, the natural 3D range data are altered and sampling error may be introduced. This paper presents a method that compresse...

This study has been inspired by the paper "An efficient 3D topology optimization code written in MATLAB” written by Liu and Tovar (2014) demonstrating that SIMP-based three-dimensional (3D) topology optimization of continuum structures can be implemented in 169 lines of MATLAB code. Based on the above paper, we show here that, by simple and easy-to-understand modificati...
