Abstract: 본발명은관절간격을측정하는방법에있어서, a) 엑스레이(X-ray) 영상을추출하는단계, b) 비선형이방성분산필터(Coherence filter)를이용하여영상의경계선을보다선명하게하는단계, c) 상기엑스레이(X-ray) 영상으로부터로컬바이너리피팅법(LBF)법을이용하여관절의컨투어(contour)를추출하는단계, d) 상기관절의컨투어(contour)에의해서뼈 사이공간의간격을수치화하는단계를포함하는것을특징으로하는발명이다. 본발명에의하면관절사이의간격을수치화하여정확하게측정할수 있으며, 관절간격을측정하여정확한진단이가능하게된다.

Abstract: PURPOSE: A joint gap measurement method which uses a local binary pitting method is provided to measure a gap between bones, thereby providing a cause of an arthritis related bone disease and a treatment method thereof. CONSTITUTION: An X-ray image is extracted. A boundary line of an image is clearly arranged using a nonlinear anisotropic distribution filter. A contour of a joint is extracted using a local binary pitting method from the X-ray image. The gap between bones is quantified by the contour of the joint. An image conversion step which arranges blurry contrast in a background image excluding the image of the boundary line is included in the above boundary line clarification step.
