Abstract :
A preliminary version of a thoracic imaging system developed to help facilitate the noninvasive locating of a coronary bypass graft for subsequent flow patency evaluation by iodine X-ray fluorescence is discussed. The imaging technique utilizes the selective measurement of Compton backscattered X-rays to inexpensively construct an effective tomographic image of the heart-lung field where grafts are located. Background theory, system design, and preliminary results are presented
