Journal ArticleDOI
Two-dimensional ionization chamber arrays for IMRT plan verification.
Bjoern Poppe,Arne Blechschmidt,Armand Djouguela,Ralf Kollhoff,A Rubach,Kay Willborn,Dietrich Harder +6 more
TL;DR: Both versions of two-dimensional ionization chamber arrays, together with the developed treatment plan verification strategy, have been found to provide a suitable and easy-to-handle quality assurance instrument for IMRT.
Journal ArticleDOI
A Triple Gaussian Pencil beam Model for Photon beam Treatment Planning
W. Ulmer,Dietrich Harder +1 more
TL;DR: The triple Gaussian pencil beam algorithm is used to demonstrate the field size dependence of the photon beam depth dose curve and its coefficients and parameters have been optimized using Fourier transform methods.
Journal ArticleDOI
Dosimetric characteristics of a new unshielded silicon diode and its application in clinical photon and electron beams.
TL;DR: An excellent performance of the new unshielded diode for the special dosimetric tasks in small photon fields, electron beams and build-up regions of photon beams has been observed.
Journal ArticleDOI
Spatial resolution of 2D ionization chamber arrays for IMRT dose verification: single-detector size and sampling step width.
TL;DR: Overall it is shown that the spatial resolution of the 2D-ARRAY Type 10024 is appropriate for the dose verification of IMRT plans and the insights obtained are also applied in the discussion of other available two-dimensional detector arrays.
Journal ArticleDOI
DAVID--a translucent multi-wire transmission ionization chamber for in vivo verification of IMRT and conformal irradiation techniques.
Björn Poppe,Christian Thieke,D Beyer,Ralf Kollhoff,Armand Djouguela,A. Rühmann,Kay Willborn,Dietrich Harder +7 more
TL;DR: The DAVID system is presented, which is able to perform permanent in vivo verification of IMRT photon beam profiles by a radiation detector with spatial resolution while the patient is treated, and the values measured are stored as reference values after the dosimetric verification of an IMRT plan.
