Discussion,This introduces problems of instrumental as well as of methodological nature. As an X-ray installation is used as a part of the measurement installation, its properties have been investigated. The spatial image transfer characteristics of modern image intensifiers pose no principal problems, but the

The X-ray Installation as a Part of the Measurement System, was recorded on a drawing table by means of a mechanical construction which could be moved with respect to the patient. By moving the X-ray tube along the heart shadow’s border, a point-by-point registration of the undistorted heart contour was obtained (orthodiagraphy).

Fractionized Contrast Medium Injection,bed in detail by SCHAD (1967). Several types of electromechanical injectors have become commercially available since. Investigation of the flow characteristics of injection catheters (KROVETZ,1966; BOVE,1968; SUSMAN,1969) has led to the development of flow-controlled injectors.
