Abstract
The goal of this study, is to use Mask Technique and Center Detection for developmental dysplasia of the Hip (DDH) diagnosis [7] which aims at calculating center and diameter of Head of Femur to diagnose some of the effects of Developmental Dysplasia of the Hip (DDH) on the hip joint. This study uses the Mask Technique and Center detection to complete the calculation of the acetabular angle and the distance of the head of femur from acetabulum. These two new criteria give the doctor very valuable information in the diagnosis of DDH and its degree. An algorithm is designed to do the following steps: 1. Exploring the details of the X-Ray and cutting out the necessary parts (acetabular bone and head of femur) for the desired side (right or left) instead of using the complete image. 2. Enhance the cropped parts by using Contrast linear stretching, Median filter and Canny edge detection. 3. Search for the center of the head of femur and calculate its diameter. 4. Measure the angle of acetabular bone and measure the distance from head of femur to acetabular bone. At last the features are extracted (Center of head of femur, Intensity value of the center, Diameter of head of femur, angle of acetabulum and distance from head of femur to the acetabulum, place in acetabulum bone). We applied this system in computer using Matlab 7.0 programming Langue.
