quantitative and model-based prediction of security in the architecture design stage facilitates early detection of design faults hence reducing modification costs in subsequent stages of software life cycle. however, an important question arises with respect to the accuracy of input parameters. in practice, security parameters can rarely be estimated accurately due to the lack of sufficient kn...

INTRODUCTION Fast and accurate quantification of abdominal adipose tissues has been a challenge. Traditionally, non-water-saturated (NWS), T1-weighted (T1W) techniques have been used for abdominal fat quantification on humans. Although fat signal is usually significantly higher than non-fat tissues, image quality is complicated by the relatively low signal-to-noise ratio and/or contrast-to-nois...

Objective(s): Single-photon emission computed tomography (SPECT) using metaiodobenzylguanidine (MIBG) is an important diagnostic tool for the treatment of refractory pheochromocytoma and paraganglioma (PPGL). Owing to the difficulty of SPECT quantification, the tumour-to-background ratio (TBR) is used to assess disease activity. However, the utility of TBR is limited o...

AIMS The aim of this study was to evaluate seven methods for quantifying myocardial oedema [2 standard deviation (SD), 3 SD, 5 SD, full width at half maximum (FWHM), Otsu method, manual thresholding, and manual contouring] from T2-weighted short tau inversion recovery (T2w STIR) and also to reassess these same seven methods for quantifying acute infarct size following ST-segment myocardial infa...

materials and methods in the first stage, no2 pollutant concentrations were measured using the data collected from air pollution monitoring stations. sampling was performed in six stations. the chosen stations have been based on the us environmental protection agency (epa) standards. in the next step, the data were processed using excel software and information was given to the airq model. data...

Introduction / objectives Serotype replacement is a major concern following the introduction of polysaccharide-conjugated vaccine against S. pneumoniae and requires a close monitoring in the population. Antibody-based serotyping methods are expensive, semi quantitative, cross-reactions are common and a significant number of isolates cannot be typed. Multiplex PCR-based assays have been develope...

Background Adenosine stress MR shows high sensitivity and intermediate-to-high specificity; therefore, there is a number of false positive patients that is referred to useless coronary angiography studies after a positive adenosine stress MR. We sought to verify whether the (semi) quantification of the amount of ischemic myocardium can improve the management of patients after a positive adenosi...

flow visualization for the same volunteer examined at 1.5T (left) and 3T (right). Top: Time-average 3D PC-MRA was calculated from the 4D data and displayed as gray shaded semi transparent iso-surface. Bottom: Two emitter plane (top right) were used to generate systolic 3D steam-lines by forward / backward tracing of the measured threedirectional velocity vector field. Flow quantification was pe...

We present a software prototype for semi-automatic segmentation and quantification of lung nodules. The system is based on an image analysis platform, which enables users to develop different image analysis solutions for different data modalities. The technology behind the platform is the Definiens Cognition Network Technology®, which is a context-driven approach based on objects and knowledge....
