Approach: In this work, we plan instead to explore the use of structured light techniques for acquiring 3D. These techniques [4] acquire 3D shape by projecting a grid on a subject’s face. By analyzing the deformations of these lines, the 3D shape is inferred. The advantage of using structured light is that it enables frame-rate capture of 3D (unlike Cyberware), and acquires more accurate 3D tha...

Artificial Intelligence (AI) planning techniques, particularly hierarchical task network (HTN) planners, can produce very complex plans, with many sequential and parallel actions decomposed into multiple levels of abstraction. Most such planners provide only a twodimensional (2D) display of such plans which is typically limited to visualization of one layer of the plan at a time. These 2D displ...

background: this study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the digital imaging and communications in medicine (dicom) format file. materials and methods:  to create the bolus with a 3d printer, we converted data in the dicom format to the stereolith...

A three-dimensional (3D)-printed customized bolus (3D bolus) can be used for radiotherapy application to irregular surfaces. However, bolus fabrication based on computed tomography (CT) scans is complicated and also delivers unwanted irradiation. Consequently, we fabricated a bolus using a 3D scanner and evaluated its efficacy. The head of an Alderson Rando phantom was scanned with a 3D scanner...

BACKGROUND Tibial plateau fractures are a common intra-articular injury for which computed tomography (CT) scans are routinely used for preoperative planning. Three-dimensional reconstructions of CT scans have been increasingly investigated in recent years, however their role has yet to be defined. We wish to investigate the role of three-dimensional computed tomography reconstructions (3D-CT) ...

RaySearch RayStation Fallback (FB) planning module can generate an equivalent backup radiotherapy treatment plan facilitating treatment on other linear accelerators. FB plans were generated from the RayStation FB module by simulating the original plan target and organ at risk (OAR) dose distribution and delivered in various backup linear accelerators. In this study, helical tomotherapy (HT) bac...

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...

This work aims at three goals: first, to define a set of statistical parameters and plan structures for a 3D pretreatment thoracic and prostate intensity-modulated radiation therapy (IMRT) quality assurance (QA) protocol; secondly, to test if the 3D QA protocol is able to detect certain clinical errors; and third, to compare the 3D QA method with QA performed with single ion chamber and 2D gamm...

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...

In recent years recognition of the important role transport plays in supporting a socially inclusive community has underpinned significant investments in public transport in Victoria. Most notably, the Victorian Government’s ‘Meeting Our Transport Challenges’ (MOTC) strategy, released in May 2006, placed a strong emphasis on social outcomes. The MOTC included plans for wide-ranging investments ...
