目的探讨16层螺旋CT三维容积重建(16-SCT VR)在鼓室成形术中的应用。方法对40例慢性化脓性中耳炎患者(40耳,病变组)患耳和35例病变组患者对侧正常耳(35耳,正常组)的听骨链VR进行研究。①采用薄层(层厚1.0 mm),小视野(FOV=5 cm),密集重建(间隔0.1 mm)技术行16-SCT扫描,获得常规断层图像及VR成像。②由2名影像科医师用盲法阅片,对断层图像和VR图像上听骨链各结构显示质量进行评价,并由此确定鼓室成形术分型。③完成鼓室成形术,将两种图像分型结果与手术结果进行对比。结果 16-SCT VR能直观立体地显示听骨链的形态及相互关系,除镫骨底板外,能清晰显示正常听骨链及其细小结构。病变组中VR图像显示:锤骨头破坏13例,锤骨柄破坏13例,砧骨体破坏15例,砧骨长脚破坏20例,砧骨短脚破坏12例,镫骨上结构破坏13例。38例VR图像术前鼓室成形术分型与手术结果一致(Ⅰ型4例,Ⅱ型19例,Ⅲ型10例,Ⅳ型5例)。结论通过选择两种阈值和两个视角,16-SCT VR具有快速、无创、准确地显示正常及异常听骨链的立体影像等优点,为慢性化脓性中耳炎的诊断及治疗提供更多的信息。 相似文献

Current virtual reality (VR) and augmented reality (AR) tools do not lend themselves well to the simulation of non-repetitive activities that could be involved in road construction and heavy civil engineering projects. Therefore it is argued in this paper that specialised functions are required to support the use of VR and AR tools to visually design and simulate such projects. The prime objective of this study is to develop visual design and simulation analysis functions to support optimum road design by extending the applicability of current virtual reality (VR) systems to the design phase of road construction projects. The VR simulation functions developed in this research enable visual inspection of road alignment and earthwork status, simulation of alternative routes, and selection of optimum design route. This study implements a methodology for configuring VR simulation functions and develops a VR system for optimising the road design data. The research results include an improved road design process as a result of the application of the VR functions developed. 相似文献

Construction workers’ ability to identify and assess risks is acquired through training and experience and is among the key factors that determine their behaviour and thus their safety. Yet researchers have questioned the effectiveness of conventional safety training. This research tested the hypotheses that safety training in a virtual reality (VR) construction site would be feasible and more effective, in terms of workers’ learning and recall in identifying and assessing construction safety risks, than would equivalent training using conventional methods. Sixty-six subjects were provided training in construction safety and their safety knowledge was tested prior to the training, immediately afterward, and one month later. Half of the subjects received traditional classroom training with visual aids; the other half were trained using a 3D immersive VR power-wall. Significant advantage was found for VR training for stone cladding work and for cast-in-situ concrete work, but not for general site safety. VR training was more effective in terms of maintaining trainees’ attention and concentration. Training with VR was more effective over time, especially in the context of cast-in-situ concrete works. Given the need for improved training and the advantages of training using VR, incorporation of VR in construction safety training is strongly recommended. 相似文献

Ventilation rates (VRs) in buildings must adequately control indoor levels of pollutants; however, VRs are constrained by the energy costs. Experiments in a simulated office assessed the effects of VR per occupant on perceived air quality (PAQ), Sick Building Syndrome (SBS) symptoms, and decision‐making performance. A parallel set of experiments assessed the effects of VR per unit floor area on the same outcomes. Sixteen blinded healthy young adult subjects participated in each study. Each exposure lasted four hours and each subject experienced two conditions in a within‐subject study design. The order of presentation of test conditions, day of testing, and gender were balanced. Temperature, relative humidity, VRs, and concentrations of pollutants were monitored. Online surveys assessed PAQ and SBS symptoms and a validated computer‐based tool measured decision‐making performance. Neither changing the VR per person nor changing the VR per floor area, had consistent statistically significant effects on PAQ or SBS symptoms. However, reductions in either occupant‐based VR or floor‐area‐based VR had a significant and independent negative impact on most decision‐making measures. These results indicate that the changes in VR employed in the study influence performance of healthy young adults even when PAQ and SBS symptoms are unaffected. 相似文献
