Description

Abdeckungsvorrichtung zur Begrenzung des Einstrahlungs feldes von Röntgenstrahlen Bei Röntgenbestrahlungen soll nach Möglichkeit nur dasjenige Gebiet der Strahlung ausgesetzt werden, welches einer diagnostischen Beurteilung bzw. therapeutischen Behandlung unterzogen werden soll. Je kleiner das Einstrahlungsfeld ist, desto kleiner ist das durchstrahlt Körpervolumen und die von ihm ausgehende Streustrahlung und desto besser auch die Quali- trjj von Röntgenaufnahmen. Die Begrenzung der Einstrahlungsfelder von Röntgen- strahlen uird im allgemeinen durch fokusnahe Blenden bzw. einen mit Blei ausgekleideten Tubus vorgenommen. Da sich hierdurch eine ausreichend genaue Feldbegrenzung häufig nicht er reichen läßt, ist man dazu übergegangen, das Einstrahlungs -feld insbesondere in der Röntgentherapie zusätzlich noch durch Bleiabdeckungen zu begrenzen.

S ChUtBID1Sprliohe Covering device for limiting the irradiation field of X-rays. In the case of X-ray irradiation, only the area that is to be subjected to a diagnostic assessment or therapeutic treatment should be exposed to the radiation, if possible. The smaller the irradiation field, the smaller the body volume and that of the irradiated body scattered radiation emanating from it and the better the quality trjj from x-rays. The limitation of the radiation fields of X-ray Shine generally through diaphragms or diaphragms close to the focus. made a lead-lined tube. Since this often does not allow a sufficiently precise field delimitation he has gone over to additionally limit the irradiation field, especially in X-ray therapy, by means of lead covers.
