title: [Dosimetry and technical quality parameters of the Microfox G-10 medical direct radiographic magnification unit].
abstract: Measurements of the entry dose for four- and eightfold magnifications were carried out in phantoms and patients with the new magnification X-ray-unit Microfox G-10 (fine focus). The skin dose for the fourfold magnification is in the order of conventional radiography, at corresponding voltages. The entry dose for the fourfold magnification of a wrist is about 0.1 cGy (tube voltage 60 kVp, time 0.7 s). In addition measurements were made to determine parameters for quality control. The deviations from the German standards are discussed. Proposals are made how to implement the German Abnahmeprüfung and Konstanzprüfung.
