| 1 | Sonography of the small intestine显示文摘In the last two decades, there has been substantial development in the diagnostic possibilities for examining the small intestine. Compared with computerized tomography, magnetic resonance imaging, capsule endoscopy and double-balloon endoscopy, ultrasonography has the advantage of being cheap, portable, flexible and user-and patient-friendly, while at the same time providing the clinician with image data of high temporal and spatial resolution. The method has limitations with penetration in obesity and with intestinal air impairing image quality. The flexibility ultrasonography offers the examiner also implies that a systematic approach during scanning is needed. This paper reviews the basic scanning techniques and new modalities such as contrast-enhanced ultrasound, elastography, strain rate imaging, hydrosonography, allergosonography, endoscopic sonography and nutritional imaging, and the literature on disease-specific findings in the small intestine. Some of these methods have shown clinical benefit, while others are under research and development to establish their role in the diagnostic repertoire. However, along with improved overall image quality of new ultrasound scanners, these methodshave enabled more anatomical and physiological changes in the small intestine to be observed. Accordingly, ultrasound of the small intestine is an attractive clinical tool to study patients with a range of diseases. | Kim Nylund Svein Фdegaard Trygve Hausken Geir Folvik Gülen Arslan Lied Ivan Viola Helwig Hauser Odd-Helge Gilja | 2009 | World Journal of Gastroenterology2009，15，11： | 9 |
| 2 | Advanced imaging and visualization in gastrointestinal disorders显示文摘Advanced medical imaging and visualization has a strong impact on research and clinical decision making in gastroenterology. The aim of this paper is to show how imaging and visualization can disclose structural and functional abnormalities of the gastrointestinal (GI) tract. Imaging methods such as ultrasonography, magnetic resonance imaging (MRI), endoscopy, endosonography, and elastography will be outlined and visualization with Virtual Reality and haptic methods. Ultrasonography is a versatile method that can be used to evaluate antral contractility, gastric emptying, transpyloric flow, gastric configuration, intragastric distribution of meals, gastric accommodation and strain measurement of the gastric wall. Advanced methods for endoscopic ultrasound, three-dimensional (3D) ultrasound, and tissue Doppler (Strain Rate Imaging) provide detailed information of the GI tract. Food hypersensitivity reactions including gastrointestinal reactions due to food allergy can be visualized by ultrasonography and MRI. Development of multi-parametric and multi-modal imaging may increase diagnostic benefits and facilitate fusion of diagnostic and therapeutic imaging in the future. | Odd Helge Gilja Jan G Hatlebakk Svein φdegaard Arnold Berstad Ivan Viola Christopher Giertsen Trygve Hausken Hans Gregersen | 2007 | World Journal of Gastroenterology2007，13，9： | 2 |

| 7 | Visualization Working Group at TU Wien Visible Facimus Quod Ceteri Non Possunt显示文摘Building-up and running a university-based research group is a multi-faceted undertaking.The visualization working group at TU Wien(vis-group)has been internationally active over more than 25 years.The group has been acting in a competitive scientific setting where sometimes contradicting multiple objectives require trade-offs and optimizations.Research-wise the group has been performing basic and applied research in visualization and visual computing.Teaching-wise the group has been involved in undergraduate and graduate lecturing in(medical)visualization and computer graphics.To be scientifically competitive requires to constantly expose the group and its members to a strong international competition at the highest level.This necessitates to shield the members against the ensuing pressures and demands and provide(emotional)support and encouragement.Internally,the vis-group has developed a unique professional and social interaction culture:work and celebrate,hard and together.This has crystallized into a nested,recursive,and triangular organization model,which concretizes what it takes to make a research group successful.The key elements are the creative and competent vis-group members who collaboratively strive for(scientific)excellence in a socially enjoyable environment. | Hsiang-Yun Wu Aleksandr Amirkhanov Nicolas Grossmann Tobias Klein David Kouřil Haichao Miao Laura R.Luidolt Peter Mindek Renata G.Raidou Ivan Viola Manuela Waldner M.Eduard Gröller | 2021 | Visual Informatics2021，5，1： | 0 |
