摘　　要：目的 探讨盆腔三维可视化模型在经阴道超声检查中的应用.方法 选取2002-2003年第三军医大学解剖学教研室创建的第2例中国女性数字化可视人体数据集,在Amira 5.2.2三维可视化软件中构建盆腔三维可视化模型,结合经阴道超声检查进行虚拟断层解剖学观察,观察盆腔主要结构的形态、空间位置关系,并与超声检查的常规切面进行对照研究.结果 本研究成功构建了高精度盆腔三维可视化模型,该模型能清晰显示任意断层方位上的所有解剖结构,包括子宫、输卵管、卵巢、膀胱、直肠、输尿管、动脉、静脉；并能模拟经阴道超声常用切面的切割,成功获得了与超声图像相对应的断层图像,这些图像的解析度、分辨率与原始断层图像近似,图像上的解剖结构极易识别.结论 基于第2例中国女性数字化可视人体数据集的盆腔三维可视化模型为妇科经阴道超声检查提供了详实、准确的解剖学资料,有利于医师对盆腔超声图像的认识和理解,并可对盆腔病变精确定位.Objective To explore the application value of three-dimensional （3D） female pelvic visualization model on transvaginal gynecological ultrasound imaging.Methods The second digital Chinese woman visible human datasets was selected,and a female pelvicvoxel-based model was constructed in Amira software for analog simulation combined with transvaginal gynecological ultrasound.The main structures and the space position variation of female pelvic cavity were observed,and the comparison study with conventional section of ultrasound was carried out.Results A high accuracy 3D visualization model of female pelvic was successfully constructed,and the anatomy structures can be dynamically and clearly displayed in any section orientation.An analog simulation research was carried out according to the scan mode of gynecological ultrasound,and a series of high resolution images consistent with scan sections of dynamic ultrasound were obtained,which had provided the optimal scan pathway for the fast inspection of the uterus,fallopian tubes and ovaries.Conclusion The 3D female pelvic visualization model based on digital Chinese woman human datasets has provided detailed and accurate anatomy information for transvaginal gynecological ultrasound imaging,which could be the benefit for doctors to understand the ultrasound images of female pelvic,as well as the accurate positioning ability to the lesions of female pelvic cavity.
