Abstract
A method and system for locating an opaque region, such as a heart region in a chest X-ray radiograph is disclosed. In order to segment a heart region in a chest X-ray radiograph, a heart region boundary is generated based on lung boundaries in the chest X-ray radiograph and an average heart region model. A location of the lower boundary of the heart region in the chest X-ray radiograph is then determined. Left and right portions of the heart region boundary are independently registered to corresponding portions of the lung boundaries, and upper and lower portions of the heart region boundary are adjusted based on the left and right portions in order to form a smooth contour.
