【摘要】：女性盆腔内器官众多,结构复杂,其内毗邻的泌尿(膀胱、尿道)、生殖(子宫、阴道)和消化(直肠)三大系统间关系密切。对女性盆腔进行薄层断面解剖学和三维可视化研究,阐明女性盆腔内解剖结构的分布规律和空间位置关系,将有助于女性盆腔内疾病的诊断与治疗。本实验采用数字化可视人体数据集获取技术对正常女性盆腔进行无锯耗的低温铣切,获得连续盆腔解剖断面图像数据集,并观察盆腔内各个解剖结构的断面结构与分布走行。图像数据集经Photoshop 7.0软件精确对位、配准、分割后,应用3D—DOCTOR 3.5软件及实验室自主开发的三维重建软件包(3D—Lancet)2.2-dev,在微机上采用面数据和体数据绘制重建法,分别对盆腔内子宫、卵巢、输尿管、膀胱、直肠以及髂内外动、静脉及其分支等结构进行三维重建并立体显示。运用与香港中文大学合作开发的Virtual Reality 1.0可视化软件,将女性盆腔连续断面图像进行三维可视化并立体虚拟切割演示,观察女性盆腔内结构在横、冠、矢等多个切面和方位的断面解剖结构特点。主要研究结果如下: 1.采用数字化可视人体铣切技术,获取经影像扫描的数字化可视人女性盆腔数据集4套(横断位数据集3套,矢状位数据集1套),无锯耗铣切精度最薄达到0.2mm,数字化摄影分辨率最高达1,100万像素,所对应的每个24bit断面图像文件大小为32.5MB,为.TIFF文件格式。 2.选择其中一套正常女性盆腔连续薄层断面图像数据,进行图像的精确配准和格式转换,将断面图像与相对应的CT、MR图像对照研究,完成女性盆腔断面影像解剖结构的对照观察和数据测量。 3.运用连续图像分割软件,分别对骨盆、子宫、卵巢、输尿管、膀胱、直肠以及盆腔内的髂内外动静、脉及其分支等结构进行结构数据的分割与提取,并在PentiumⅣ计算机上完成女性盆腔内主要解剖结构的三维重建。 4.受Talairach脑图谱空间思路的启发,以典型解剖结构为标志,选择坐标轴和坐标面,建立盆腔可视化模型的三维坐标,为盆腔解剖数据的深入分析、女性盆腔解剖图谱和影像图像的配准以及盆腔虚拟手术的导航等建立基本的框架。 5.建立女性盆腔可视化解剖模型,为数字化解剖学的开展提供可视化教学平台,并
[Abstract]:The female pelvic organs are multitudinous and complex in structure. There is a close relationship between the urinary system (bladder, urethra), reproduction (uterus, vagina) and digestive system (rectum) adjacent to the female pelvic organs. It is helpful to diagnose and treat female pelvic diseases by studying the thin-section anatomy and three-dimensional visualization of female pelvis in order to clarify the distribution of female pelvic anatomical structure and the relationship between space and location. In this experiment, the digital visual human data set was used to milling the normal female pelvis at low temperature without sawing consumption. The continuous pelvic anatomical cross-section image data sets were obtained, and the cross-section structure and distribution of each anatomical structure in the pelvic cavity were observed. The image data set is accurately aligned, registered and segmented by the software Photoshop 7.0.After using 3D-DOCTOR 3.5 software and the 3-D reconstruction software package (3D-Lancet) developed by the laboratory, the software package (3D-Lancet) is 2.2, devv. Three-dimensional reconstruction and stereoscopic display of pelvic uterus, ovary, ureter, bladder, rectum, internal and external iliac artery, vein and its branches were performed by the reconstruction method of surface data and volume data on microcomputer. Using the visual software Virtual Reality 1.0developed in collaboration with the Chinese University of Hong Kong, the continuous section images of female pelvis were visualized and three-dimensional virtual cutting was performed to observe the structure of female pelvic cavity in transverse and crown. Features of cross-sectional anatomy of sagittal sections and orientations. The main findings are as follows: 1. Using digital visual human milling technology, 4 sets of digital visible human female pelvic data set (3 sets of cross-section data set and 1 set of sagittal data set) have been obtained by image scanning. The sagittal data set has a sagittal data set of 1 set, the sagittal data set is 1 set, and the sagittal data set is 1 set. The resolution of digital photography is up to 11 million pixels, and the size of each 24bit section image file is 32.5MB, which is .TIFF file format. 2. Select one set of normal female pelvic continuous thin section image data, carry on the accurate registration and format transformation of the image, and compare the cross-section image with the corresponding CT,MR image, and compare the cross-section image with the corresponding image of the female pelvis. To complete the contrast observation and data measurement of female pelvic cross-sectional anatomy. 3. The structure of pelvic, uterine, ovarian, ureter, bladder, rectum and pelvic internal and external iliac arteries, veins and branches were segmented and extracted by continuous image segmentation software.
