In general, the geometric magnification radioangiography has been taken and the large amount of contrast medium has been injected with high speed even for the angiocardiography of old patient. But we think that there are several problems in these techniques for aged patients. So we have studied these methods and got the results as follows ; 1) The different curves of MTF may be got according to the magnification rate and these curves cross with each other-So, the windths of picture have the different values compared to the true it. 2) The good angiographic pictures are got with the slow speed injections of dye even by the low exposure of tube voltage. This method is advantageous for the aged patients who may have the low renal function. We conclude that the geometric magnification radiography shoud not be used too easily and the low exposure of tube voltage with slow speed injection technique may be useful for the angiocardiography of old ages.
