Method and system for detection of bone structure
A method for detecting bone structure includes allocating at least one bone portion from a bone image composed by pixels each including luminance value relating to bone structural parameter; aligning a major axis of principal axes of moment of inertia of the bone portion to a principal axis of Cartesian coordinate system; a cortical bone area of the bone portion intersecting at least one principal plane perpendicular to the principal axis, and each principal plane forming an outer and inner contour line of the cortical bone area; processing an analytic algorithm for the bone structural parameter; calculating distributed state of the bone structural parameter in each principal plane to obtain a distributed state of the bone structural parameter of the bone portion; and obtaining a distributed state of the bone structural parameter of the bone portion by assembling distributed state of the bone structural parameter of each bone portion.
