This was a study of the use of virtual reality modelling language (VRML) for cross-platform interactive three-dimensional (3-D) visualization of high-resolution magnetic resonance (MR) images of the inner ear in the assessment of cochlear implant candidates.A retrospective case review was made of cochlear implant candidates undergoing pre-operative high-resolution MR studies to determine their suitability for implantation. 3-D visualizations of MR scans of the inner ear structures were created using surface rendering and exported as portable VRML files.Case studies are presented to illustrate different points of interest. VRML reconstructions aided the interpretation of two-dimensional (2-D) source images in a variety of inner ear abnormalities.VRML is an internationally recognized standard for cross-platform 3-D visualization that creates a means of providing the implanting surgeon with a portable 3-D representation of the inner ear, aiding interpretation of the complex cross-sectional anatomy of these structures, and guiding selection of patients for implantation as well as implantation technique. The elucidation of the mechanisms behind inner ear malformations can also be aided by detailed imaging studies of the temporal bone, with VRML reconstructions providing an easily interpreted representation of deformities.

AbstractBackground:Pre-operative radiological identification of facial nerve anomalies can help prevent intra-operative facial nerve injury during cochlear implantation. This study aimed to evaluate the incidence and configuration of facial nerve anomalies and their concurrence with inner-ear anomalies in cochlear implant candidates.Methods:Inner-ear and concomitant facial nerve anomalies were evaluated by magnetic resonance imaging and temporal high-resolution computed tomography in 48 children with congenital sensorineural hearing loss who were cochlear implant candidates.Results:Inner-ear anomalies were present in 11 out of 48 patients (23 per cent) and concomitant facial nerve anomalies were present on 7 sides in 4 patients (7 per cent of the total). Facial nerve anomalies were accompanied by cochlear or vestibular malformation.Conclusion:Potential facial nerve abnormalities should always be considered in patients with inner-ear anomalies. Pre-operative facial nerve imaging can increase the surgeon's confidence to plan and perform cochlear implantation. Magnetic resonance imaging should be used to detect inner-ear anomalies; if these are identified, temporal high-resolution computed tomography should be used to evaluate the facial nerve.

This chapter evaluates current possibilities for the attainment of a realistic context over the web by attempting to match the basic requirements of art history scholarship and teaching against what is currently offered and what can be expected in the future. It surveys some ongoing research in the field from the perspective of an observer and a user. The first section of the chapter discusses virtual reality modelling language (VRML) and describes a project of the Supercomputer Group at the Australian National University. This project aimed to model, using VRML, the Buddhist stupa at Borobudur. The chapter also discusses a second project which deals with the Piazza de Popolo at Rome and the reasons why this project did not employ VMRL. The second section of the chapter examines some other ways in which an ordinary lecturer may use various simple technologies to conjure context, and with more flexibility, detail and accuracy that VRML can ever achieve.

Peranan teknologi informasi menjadi hal utama yang harus dipenuhi untuk menunjang kegiatan dalam berbagai bidang kehidupan, tidak terkecuali bidang promosi suatu produk atau jasa. Dengan penggunaan internet penyampaian informasi mengenai produk yang dipromosikan menjadi lebih mudah dan dapat diakses setiap saat dan dapat dilakukan dimana saja. Medianya pun juga telah berkembang dengan berbagai macam kemudahan, salah satunya adalah media promosi berbasis multimedia. Teknologi virtual reality merupakan salah satu teknologi yang berbasis multimedia dengan memadukan berbagai elemen multimedia. Dengan penggunaan teknologi virtual reality tersebut diharapkan dapat menunjang media promosi agar lebih interaktif, efektif dan menarik. Aplikasi yang dikembangkan merupakan perpaduan antara teknologi virtual reality dengan website. Teknologi virtual reality akan menyajikan produk mobil yang dipromosikan melalui tampilan tiga dimensi yang interaktif. Teknologi tersebut kemudian ditanamkan dalam website sehingga memungkinkan pengguna dapat mengaksesnya kapan dan dimana saja. Teknologi virtual reality dikembangkan menggunakan VRML (Virtual Reality Modelling Language) dan software pemodelan 3D 3ds Max, sedangkan aplikasi berbasis web dikembangkan menggunakan bahasa pemrograman PHP, HTML dan CSS. Aplikasi tersebut juga didukung penggunaan basis data MySQL sehingga mempermudah user dalam mengolah data. Browser yang digunakan perlu dipasangi plug-in Cortona3D Viewer agar dapat menampilkan file tiga dimensi. Hasil dari pembuatan aplikasi ini adalah terancangnya sebuah aplikasi yang menggunakan teknologi VRML untuk media promosi mobil berbasis web. Hasil pengujian menunjukkan bahwa aplikasi ini menjalankan fungsionalitasnya sesuai dengan rancangan.

Objective 1) To determine pediatric cochlear implant performance outcomes for hearing loss secondary to bacterial meningitis. 2) To determine if a performance difference exists in pediatric cochlear implant patients with and without labyrinthitis ossificans. Methods A retrospective case review was performed at a tertiary care multi-disciplinary cochlear implant program. 45 children were implanted from 1991 to 2006 whose hearing loss resulted from bacterial meningitis. Mode of communication, school placement and performance were reviewed. Results 21 patients(52%) were in a mainstream educational enviroment and 19 (48%) were in a special needs enviroment. 24 subjects (58%) used an auditory-verbal mode of communication, while 17 (42%) used total communication. The mean speech reception threshold was 28dB with a range from 5 to 65dB. 14 subjects (56%) had labyrinthis ossifcans, while 11 subjects (44%) did not. Conclusions The present study demonstrated that over half of our subjects developed labyrinthitis ossificans. Despite the presence of cochlear ossification, patients with bacterial meningitis-induced hearing loss can often perform in a main-stem classroom with auditory-verbal communication.

Virtual Reality Modelling Language (VRML) is description language, which belongs to a field virtual reality (VR) system. The file, which is in VRML format, can be interpreted by VRML explorer in three-dimensional scene. VRML was created with aim to represent virtual reality on Internet easier. Development of 3D graphic is connected with Silicon Graphic Corporation. VRML 2.0 is the file format for describing interactive 3D scenes and objects. It can be used in collaboration with www, can be used for 3D complex representations creating of scenes, products or VR applications VRML 2.0 enables represent static and animated objects too. Interesting application of VRML is in area of automated workplaces simulation.
