Running biomechanics play an important role in the development of injuries. Performing a running biomechanics analysis on injured runners can help to develop treatment strategies. This article provides a framework for a systematic video-based running biomechanics analysis plan based on the current evidence on running injuries, using 2-dimensional (2D) video and readily available tools. Fourteen...

Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...

The paper describes the outline of 2D-discrete cosine change (DCT) which is generally utilized as a part of picture and video pressure calculations. The target of this paper is to plan a completely parallel distributed arithmetic (DA) architecture for two dimensional (2D) DCT to be implemented in Xilinx. DCT requires extensive measure of scientific calculations including multiplications and col...

Nowadays, with the rapid development of 3D building model based applications, there is an urgent demand to develop automatic techniques for integrating 3D outdoor building models with 2D and 3D indoor information to produce semantically, geometrically and topologically correct 3D building models. 3D terrestrial laser scanning (TLS) data provides the accurate 3D geometric information, whereas 2D...

Introduction: Maxillary canines have important roles in facial appearance, development of arch, and functional occlusion. Radiographs are important in evaluating the location and nature of these anomalies. The purpose of this study was to evaluate two types of 2D and 3D imaging technique in diagnosis and treatment of maxillary impacted canines. Methods: Thirty eight patients (50 impacted canine...

Introduction: The use of electronic portal imaging devices (EPIDs) is a method for the dosimetric verification of radiotherapy plans both pretreatment and in-vivo. The aim of this study was to test a 2D EPID-based dosimetry algorithm for dose verification of some plans inside a homogenous and anthropomorphic phantom and in-vivo, as well. Materials and Methods: </strong...

PURPOSE A lower than ideal tolerance limit is used in intensity-modulated radiation therapy quality assurance (IMRT QA) with a 2D diode array due to passing rate fluctuations. The objective is to identify patterns in the passing rates to predict sources of uncertainty that can affect treatment delivery, for example, the need to re-calibrate the multileaf collimator when the passing rates start ...
