This paper presents a random variate generation (RVG) world wide web (web) service and an RVG web-based software application, both of which are developed in compliance with the Java 2 Enterprise Edition (J2EE) architecture and run under the IBM WebSphere Application Server. The RVG web service can be invoked programmatically over the web by using simple object access protocol (SOAP) through the...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

objective: after introduction of digital radiography into dentistry several methods of image acquisition were accessible in the field of dentistry. in many instances it is necessary to digitize analog images. there is no overall acceptable method for image digitization so all different types of images can be comparable. the objective of this study was to compare the diagnostic accuracy of diffe...

OBJECTIVES To compare the differences between conventional radiography and digital computerized radiography (CR) in patients presenting to the emergency department. METHODS The study enrolled consecutive patients presenting to the emergency department who needed chest radiography. Quality score of the radiogram was assessed with visual analogue score (VAS-100 mm), measured in terms of millime...

OBJECTIVES We assessed the abilities of two methods to measure ejection fraction (EF)-radionuclide ventriculography (RVG) and contrast left ventriculography (Cath-EFa) to predict cardiovascular events. BACKGROUND Both RVG and Cath-EFa are commonly used methods to measure left ventricular performance and assess prognosis. Their comparative abilities to predict clinical events have not been rep...

introduction: various systems for intraoral digital radiography have been available as an alternative to film–based radiography. in consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of im age quality and elimination of processing, it has been extensively used in different fields of denti stry in recent years. the purpose of this study wa...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...
