Characterization of an extendable multi-leaf collimator for clinical electron beams
O'Shea, Tuathan P.; Foley, Mark J. (Institute of Physics, 2011)An extendable x-ray multi-leaf collimator (eMLC) is investigated for collimation of electron beams on a linear accelerator. The conventional method of collimation using an electron applicator is impractical for conformal, ... -
Electron beam therapy at extended source-to-surface distance: a monte carlo investigation
O'Shea, Tuathan P.; Foley, Mark J.; Rajasekar, David; Downes, Patrick A.; van der Putten, Wil; Moore, Margaret; Shearer, Andrew (Wiley-Blackwell, 2008-09-01)Electron-beam therapy is used to treat superficial tumors at a standard 100 cm source-to-surface distance (SSD). However, certain clinical situations require the use of an extended SSD. In the present study, Monte Carlo ... -
Monte Carlo commissioning of clinical electron beams using large field measurements
O'Shea, Tuathan P.; Foley, Mark J. (Institute Of Physics (IOP Publishing), 2010-07-21)Monte Carlo simulation can accurately calculate electron fluence at the patient surface and the resultant dose deposition if the initial source electron beam and linear accelerator treatment head geometry parameters are ...
