Notes:
Coronary angiography by intravenous injection of contrast material using synchrotron radiation (SR) is a safe and easy method for diagnosis of coronary arteries. In Japan, a two-dimensional imaging system for coronary angiography is being developed. In that case, there exists a problem: Image contrast and visibility deteriorate due to harmful scattering x rays which are made when passing through a patient's body. Therefore, we have developed a simulation program in order to study the x-ray scattering behavior in a subject using monochromatic x rays and to find a method to decrease the scattering x rays in images using x-ray grids. The calculated results concerning the scattering x rays using the simulation program were compared with experimental results using monochromatic x rays at 33.17 keV from synchrotron radiation. © 1995 American Institute of Physics.
