Texture Enhancement of X-ray Images of Ischemic Femoral Head Necrosis

In view of the low imaging resolution of conventional hip joint X-ray examination and the problems of misdiagnosis and missed diagnosis caused by manual reading, it proposed a method for enhancing the texture details of hip joint X-ray images which combines specific clinical needs. First, it preprocessed the X-ray images of the hip joint. Then it removed the labels and scales of the images, and selected a dual windows which suitable for the X-ray images of the hip joint to obtain the local extreme images. Finally, the detail images obtained from the local extreme images and the original image were combined to enhance the texture of the hip joint X-ray images. In this paper, 210 X-ray images of the hip joint were selected for texture enhancement. The experimental results show that this method highlights the internal bone texture of the femoral heads in the Xray images of the hip joint and achieved the enhancement effect.
