OBJECTIVE The goal of this project was to define and measure human airway space with radiographic volumetric 3-dimensional imaging and digital reconstruction of the pharynx using cone-beam computerized tomography. STUDY DESIGN This was a randomized retrospective study. Ten patient scans were selected randomly from a pool of 196 subjects seeking dental treatment at the University of California...
Background and Objective: Computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. This study aims to compare and contrast the success of biopsy under guide...
موضوع اصلی مورد بحث در این پایان نامه «استفاده از الگوی متن دوسویه به عنوان ابزاری کار آمد برای جذب مخاطب در رادیو» می باشد. به عبارت دقیق تر با ارائ? مدلی مبتنی بر تکنیک "interactive digital storytelling" ، مدلی برای نویسندگی دوسویه در رادیو ارائه می دهیم که با استفاده از آن می توان از پتانسیل «مخاطب فعال» برای ایجاد رابطه ای تخصصی شده و پایدار بین مخاطب و رسان? رادیو استفاده کرد.
In 2011, the first consensus conference on guidelines for the use of cone-beam computed tomography (CBCT) was convened by the Swiss Society of Dentomaxillofacial Radiology (SGDMFR). This conference covered topics of oral and maxillofacial surgery, temporomandibular joint dysfunctions and disorders, and orthodontics. In 2014, a second consensus conference was convened on guidelines for the use o...
We study the problem of determining in a constructive way a convex body in the plane from its tomographic projections. For this, we consider the similar problem in digital plane: reconstructing a lattice convex set from its discrete tomographic projection. We show that we can use a reconstruction algorithm for the discrete problem to solve the continuous reconstruction to any precision. The pro...

Reverse-time migration can accurately image complex geologic structures in anisotropic media. Extended images at selected locations in the earth, i.e. at commonimage-point gathers (CIPs), carry enough information to characterize the angle-dependent illumination and to provide measurements for migration velocity analysis. Furthermore, inaccurate anisotropy leaves a distinctive signature in CIPs,...
