Experimental determination of wall correction factors. Part II: NACP and Markus plane-parallel ionization chambers

Autor: A.H.L. Aalbers, Ben J. Mijnheer, F.W. Wittkämper

Publikováno v: Physics in Medicine and Biology. 37:995-1004

For pt.I see ibid., vol.35, p.835-46 (1990). The formalism to derive the absorbed dose to water from ionization chamber measurements in a phantom includes several wall correction factors, katt, km and pwall, that depend on the shape, size and composi
