1058-68 A virtual heart model for image orientation and teaching three-dimensional echocardiography

Three-Dimensional Image of A Communicating Uterus

Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

Assessing the level of market orientation at Qazvin teaching and medical hospitals: Application of the three-dimensional market analysis model

Background: In addition to providing effective and equitable services to low-income groups, teaching hospitals must obtain a significant share of the demand of high-income groups in order to have a balanced and positive operational performance. The aim of this study was to investigate the market orientation of teaching and medical hospitals in Qazvin. Materials & Methods: This descriptive-anal...

[Three-dimensional echocardiography in carcinoid heart disease].

A 67-year-old man had presented 7 months earlier with complaints of flushing, diarrhea and tiredness. Etiologic investigation diagnosedmetastaticmidgut neuroendocrine carcinoid tumor for which he had trans-arterial embolization and started monthly sandostatin. In follow-up, he developed progressive exertional dyspnea and was referred for carcinoid heart screen. On physical examination there wer...

A Three Dimensional Image Cache for Virtual Reality

Despite recent advances in rendering hardware, large and complex virtual environments cannot be displayed with a sufficiently high frame rate, because of limitations in the available rendering performance. This paper presents a new approach of software accelerated rendering which draws from the concepts of impostors, hierarchical scene subdivision and levels of detail. So far software optimizat...
