ABSTRACT:
Methods and apparatus for precise and consistent selection of bone mineral content (BMC) measurement regions of selected bones, and accurate calculation of BMC from a displayed radiological image of the bones, calculate the position of the styloid tip of each bone, define a measurement region having selected positional correspondence to the position of the styloid tip, and sum pixel intensity values in the measurement region to yield a pixel intensity sum representative of bone mineral content. Bone density values are obtained by dividing the pixel intensity sum by a value representative of the areas of the measurement region, to yield a value representative of bone density. The position of the styloid tip is calculated by detecting selected transverse image edges, searching along the selected transverse image edges to determine a set of pixels which define extremities of the styloid tip, and defining a line substantially tangent to the styloid tip.
