1 ANALYZING THREE-DIMENSIONAL POSITION OF REGION OF INTEREST USING AN IMAGE OF CONTRAST MEDIA USING UNILATERAL X-RAY EXPOSURE

Abstract

Analyzing three-dimensional internal structure of object in an X-ray study is usually performed by using two or more of the incidents of an X-ray direction. In this report, we analyzed the three-dimensional position of tubes with a phantom by using both contrast media and imaging of one direction in the X-ray study. The concentration of the iodine in contrast media can be known by using the log-subtraction image of only the one-directional incident X-ray. Also the diameter of tube filled with contrast media is calculated by the concentration of iodine. So we can show the three-dimensional position of tubes geometrically, by the diameter of tube and the measured value of the film. We verified this method by an experiment according to the theory.
