Description

Supplementary filters are generally viewed as being a suitable method of limiting the radiation exposure of patients. The report provides information on the active mechanisms, possibilities and deficiencies of such filter materials. Additional filters are far from being a perfect remedy. The advantage of slight dose reduction is invariably cancelled out by drawbacks in respect of image contrast and exposure time. Copper is a recommended filter material that may vary in strength between 0.1 and 0.2 mm according to performance data. (orig./HP)

Abstract (German)

Zusatzfilter gelten als ein Mittel zur Verringerung der Strahlenexposition des Patienten. Der Beitrag informiert ueber Wirkungsweise, Moeglichkeiten und Grenzen potentieller Filtermaterialien. Zusatzfilter bieten kein Patentrezept. Geringe Dosisreduzierungen werden durchweg mit Nachteilen in Bildkontrast und Expositionszeit erkauft. Als Filtermaterial wird Kupfer mit 0,1 oder 0,2 mm Staerke, je nach Leistungsreserven empfohlen. (orig./HP)
