Synchrotron Radiation Coronary Angiography with Aortographic Approach

Two-dimensional synchrotron radiation (SR) coronary arteriography (CAG) with aortographic contrast injection was considered theoretically and animal experiments were performed to examine its diagnostic ability. This system consisted of a silicon monocrystal, fluorescent plate, avalanche-type pickup tube camera, and image acquisition system. The experiment was performed at synchrotron sources in the Photon Factory in Tsukuba. The x-ray energy was adjusted to just above the iodine K-edge.
