How early detection of osteonecrosis of the femoral head?

X-ray diagnosis of shares femoral head necrosis convenient, fast, the economy is an important means of the hospital routine. However, as the X-ray imaging of the three-dimensional density changes into two-dimensional images, the density of penetrating ray imaging superimposed on the film, this will result in lesions and normal minor regional differences in the gray, early identification pathological changes not easy delaying treatment. Huangkeqi professors and experts invention of "necrosis of the femoral head image machine", overcome by different X-ray imaging conditions, contrast and brightness changes, caused by the error on bone mineral density distribution. Information through enhanced, high-pass filtering, histogram enhanced, such as cluster segmentation processing, improve detection of the image, made up MRI in the diagnosis of necrosis of the femoral head of the non-specific and not visible in the image texture and morphology of bone deficiencies. And the X-ray films converted into standard eye image identifiable information, the two-dimensional human body in space in the projection of overlapping images can not fully display the information through different image processing techniques show the ultrastructure of the femoral head Pathological changes in bone mineral density and bone morphology and quantitative analysis of the extent of lesions and make early diagnosis.
