Application of Segmentation and Measurement in the Treatment of Developmental Dysplasia of the Hip
Developmental dysplasia of the hip (DDH) is a congenital hip joint malformation affecting the proximal femurs and acetabulum that are subluxatable, dislocatable, and dislocated. DDH is best treated during infancy. In this paper, we designed and implemented a computer aided system for treatment of this disease. In this system, we used a mixture-based PV partial-volume algorithm to perform bone segmentation on the patients CT (computed tomography) or MRI (magnetic resonance imaging) image, then by three-dimensional (3D)reconstruction and display of the segmented image, we can easily get the quantitative measurement of Acetabular Index (AI) and Center-Edge Angle (CEA), which can help the clinic diagnosis and treatment. PC graphics-card GPU architecture was exploited to accelerate the 3D rendering and geometric manipulation. This system was implemented on PC/Windows environment.
