A 3-D Interactive Atlas of the Maxilla, Mandible & TMJ

产品说明：该项目将制作解剖结构模型，其分辨率由于技术限制而在以前是不可能的。可视人体项目（VHP）是第一个使用连续横截面来构建体素模型的演示。虽然VHP代表了一个里程碑式的努力，它遭受有限的样本量，（两个主题），分辨率和分割问题。该项目将增加样本量，并将以更高的分辨率收集数据。然后，它将集中在一个特定的一块解剖-颞下颌关节，说明正常和异常的解剖样本，并证明关节的功能运动。第一个目标是确定上颌骨、下颌骨、颞下颌关节和周围组织的解剖结构、血管分布、神经支配、肌肉和骨骼。我们将使用在第一阶段赠款期间完善的数据收集方法。查看协议将被扩展，允许我们分割，删除和替换各种结构。此外，我们将把CT、MRI和数字摄影数据关联起来，以便更好地了解解剖结构。所有的模型都将是完全交互式的，可围绕六个轴旋转，带有注释，能够分段关闭和打开，并以立体方式观看。第二个目的是说明颞下颌关节的病理列入扫描数据的一个重要的收集头骨从加州大学旧金山分校。第三个目标是开发一个全面的TMJ图谱。它将包括关节的宏观解剖，包括关节囊解剖，神经支配，血管分布和相关的咀嚼肌。观察者将能够通过其所有的运动移动注释的关节，并观察肌肉组织如何在咀嚼和下颌运动中工作。以高分辨率对解剖结构的小离散区域进行成像的能力提供了有用的数据，这些数据具有教育意义和临床实用性，并且是对全面的高分辨率库的重要贡献。该地图集将被设计用于医学和牙科学生，口腔和颌面外科医生，放射科医生，整形外科医生和耳鼻喉科医生。

DESCRIPTION: This project will produce models of anatomical structures with a degree of resolution that, because of technological limitations, has not been previously possible. The Visible Human Project (VHP) was the first demonstration of the use of serial cross sections to build voxel models. While the VHP represent a landmark effort, it suffers from limited sample size, (two subjects), resolution and segmentation problems. This project will increase the sample size and will collect data at a dramatically higher resolution. It will then concentrate on a specific piece of anatomy - the TMJ, to illustrate normal and abnormal anatomical samples and to demonstrate the functional movements of the joint. The first Aim is to define the anatomy, vascularity, innervation, muscle, and bone of the maxilla, mandible, TMJ and surrounding tissue. We will use data collection methods perfected during the Phase I grant. Viewing protocols will be expanded, allowing us to segment, remove and replace various structures. Ancillary to this, we will correlate the CT, MRI and digital photographic data for a better understanding of the anatomy. All of the models will be fully interactive, rotatable around six axes, annotated, capable of being turned off and on segmentally and viewed in stereo. The second Aim is to illustrate the pathology of the TMJ by the inclusion of scanned data of an important collection of skulls from UCSF. The third Aim is to develop a comprehensive Atlas of the TMJ. It will include the macroanatomy of the joint including the capsular anatomy, innervation, vascularity and the associated muscles of mastication. The viewer will be able to move the annotated joint through all of its movements and observe how the musculature works in both mastication and mandibular movements. The ability to image small discrete areas of anatomy at high resolution provides useful data that is educational and clinically useful and is an important contribution to a comprehensive high-resolution library. The Atlas will be designed to be used by medical and Dental students, oral and maxillofacial surgeons, radiologists, plastic and ENT surgeons.
