三维虚拟现实成像结合二维超声图像可视化评价婴幼儿髋关节发育不良
Three-dimensional virtual reality imaging combined with two-dimensional ultrasound images for the visual evaluation of hip dysplasia in infants
摘要
Abstract
BACKGROUND:Ultrasound has been widely used in developmental hip dysplasia screening in infants and young children, but there are significant differences among different inspection findings, even in the reexamination by the same examiner. Therefore, the accuracy of ultrasound imaging in the diagnosis is of insufficient evidence. <br> OBJECTIVE:Through virtual reality three-dimensional reconstruction images showing the structure of acetabulum and femoral head space, to obtain a new parameter in order to enrich measurement standards of Graf ultrasonic diagnosis technology and to further improve the credibility of the diagnosis of developmental dysplasia of the hip. <br> METHODS:Ten fresh cadaver specimens of Chinese infants were selected, including five males and five females. Two-dimensional ultrasonic method was employed for hip screening, and at the same time, multi-slice spiral CT was used for three-dimensional reconstruction fol owed by volume reconstruction and fitting of surface reconstruction to display the anatomic structure around the hip and to simulate Graf’s two-dimensional ultrasound method to measure a andβangles on three-dimensional virtual reality images. <br> RESULTS AND CONCLUSION:As confirmed by three-dimensional reconstruction, Graf’s two-dimensional ultrasound could be used to measure a and angles, truly reflecting the development of bony and cartilaginous acetabulum. Graf’s two-dimensional ultrasound contributed to the proper evaluation of beonatal hip dysplasia, which can be used as a routine examination for developmental dysplasia of the hip. These indicate that to master Graf’s ultrasound technology and strictly grasp the evaluation standards for developmental dysplasia of the hip is the important guarantee for diagnosis of developmental dysplasia of the hip.关键词
