Measured vs simulated portal images for low MU fields on three accelerator types: Possible consequences for 2D portal dosimetry

Autor: Tim Lustberg, Sebastiaan M. J. J. G. Nijsten, Marc Orlandini, J A D Snaith, Frank Verhaegen, Mark Podesta, Trent Aland, Davy Emans

Publikováno v: Medical Physics. 39:7470-7479

Purpose: As external beam treatment plans become more dynamic and the dose to normal tissue is further constrained, treatments may consist of a larger number of beams, each delivering smaller doses (or monitor units, MU), in, e.g., volumetric modulat

Interfractional trend analysis of dose differences based on 2D transit portal dosimetry

Autor: F van Gils, F J Wilbrink, Mark Podesta, Tim Lustberg, Frank Verhaegen, J A D Snaith, L. Persoon, W. Van Elmpt, Sebastiaan M. J. J. G. Nijsten

Publikováno v: Physics in Medicine and Biology, 57(20), 6445-6458. IOP Publishing Ltd.

Dose delivery of a radiotherapy treatment can be influenced by a number of factors. It has been demonstrated that the electronic portal imaging device (EPID) is valuable for transit portal dosimetry verification. Patient related dose differences can

Radiotherapy dosimetry audit: three decades of improving standards and accuracy in UK clinical practice and trials

Autor: Andrew Nisbet, Russell Thomas, Elizabeth Miles, David Thwaites, Catharine H. Clark, J A D Snaith, K Venables, Edwin Aird, Steve Bolton

Publikováno v: The British Journal of Radiology. 88:20150251

Dosimetry audit plays an important role in the development and safety of radiotherapy. National and large scale audits are able to set, maintain and improve standards, as well as having the potential to identify issues which may cause harm to patient
