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爆米花 发表于 2025-3-27 07:10:50

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).结合 发表于 2025-3-28 04:32:18
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.NEXUS 发表于 2025-3-28 10:13:53
