Conference paper


In his talk, Dr.Yamasaki showed x-ray photographs of a patient’s lung, one taken 30 years ago and one recently, which brings us to the conclusion that there has been no significant progress in x-ray imaging technology employed in hospitals. This fact may suggest that economical compact SR sources should be developed urgently for use in hospitals in order to materialize the practical use of various new methods of using synchrotron radiation, such as coronary angiography and bronchography with energy subtraction, fluorescent x-ray CT, and multiple-energy computed tomography using monochromatic beams.
