ABSTRACT:
A method for processing a radiographic image of a patient obtains radiographic image data and detects the position of inserted tubing or other foreign object in the obtained image and determines the tubing tip or object location. A region of interest in the neighborhood of the tubing tip or object location is defined and at least one anatomy structure within the region of interest is detected. The probability for mal-positioning of the tip or object is calculated by determining the position of the tip or object relative to the at least one anatomy structure.
