Introduction. The temporomandibular joint (TMJ) is the most complex elegantly designed joint in the human body. Abnormal development and growth of TMJ may lead to condyle aplasia present in several syndromes expressions, but it is extremely rare when not connected to any underlying pathological disorder or in conjunction with any syndrome. Objective. A rare case of aplasia of the mandibular con...

At present, the development and application of outdoor navigation is already quite mature. Car navigating system and mobile navigating system have been good to meet people’s requirements to find the path in outdoor. With the development of outdoor navigation system, indoor navigation system is also being paid more attention, especially in an unfamiliar and complex indoor environment. This paper...

The goal of dental implant therapy is the accurate and predictable restoration of a patient’s dentition. These goals are best achieved when all members of the surgical and restorative team are working together on diagnosis, planning, and reconstruction. The recent introduction of new 3dimensional (3D) diagnostic and treatment planning technologies in implant dentistry have created an environmen...

Background: Radiotherapy with large mantle field is an effective technique in increasing the risk of secondary cancers among HL (Hodgkin Lymphoma) patients; therefore, it is essential to choose an effective treatment field including the least medical conditions in radiotherapy.Objective: The present study aimed to plan separate fields for neck and mediastinum using various energies, to compare ...

3D representation of Radar electromagnetic information affected by terrain, ocean and weather is an unavoidable problem in the future digital battlefield. Based on APM(Advanced Propagation Model), in-plane propagation loss was calculated by the virtual of digitalized virtual battlefield. Then 2D in-plane coverage of given Radar was deduced. At last multiple such 2D coverage were combined togeth...

3D city models are important in urban planning for sustainable development. Urban planners draw maps for efficient land use and a compact city. 3D city models based on these maps are quite effective in understanding what, if this alternative plan is realized, the image of a sustainable city will be. However, enormous time and labour has to be consumed to create these 3D models, using 3D modelli...

We propose an iterative method of 3D localization of 2D or 3D polygonal shapes by monocular vision from a sngle image. The method assumes that the size of the polygonal object is known and that the camera is calibrated. Essentially, the 3D localization is obtained by the resolution of a non-linear system using the parametric equations of the polygonal object (contour) projection in the image pl...

The success of prostate brachytherapy depends on the faithful delivery of a dose plan. In turn, intraoperative localization and visualization of the implanted radioactive brachytherapy seeds enables more proficient and informed adjustments to the executed plan during therapy. Prior work has demonstrated adequate seed reconstructions from uncalibrated mobile c-arms using either external tracking...

In the last decades, treatment planning for multicatheter interstitial breast brachytherapy has evolved considerably from fluoroscopy-based 2D to anatomy-based 3D planning. To plan the right positions of the catheters, ultrasound or computed tomography (CT) imaging can be used, but the treatment plan is always based on postimplant CT images. With CT imaging, the 3D target volume can be defined ...

Additive manufacturing, or 3D printing, is a promising manufacturing technique marred by product deformation due to material solidification in the printing process. Control of printed product deformation can be achieved by a compensation plan. However, little attention has been paid to interference in compensation, which is thought to result from the inevitable discretization of a compensation ...
