Quantification of geometric uncertainties in image guided radiotherapy [PDF]
, 2010 The aim of this thesis is to determine if the geometric uncertainties that are introduced into the image guided radiotherapy (IGRT) process by Cone Beam CT (CBCT) based IGRT equipment are sufficiently small that they do not pose a significant risk of ...

Numerical techniques for conformal mapping onto a rectangle [PDF]
, 1986 This paper is concerned with the problem of determining approximations to the function F which maps conformally a simply-connected domain onto a rectangle R, so that four specified points on are mapped Ω∂respectively onto the four vertices of R.

Numerical conformal mapping onto a rectangle with applications to the solution of Laplacian problems [PDF]
, 1988 Let F be the function which maps conformally a simple-connected domain onto a rectangle R, so that four specified points on are mapped Ω∂respectively onto the four vertices of R. In this paper we consider the problem of approximating the conformal map F,

Development of a linear array for intracavitary in vivo dosimetry during external beam radiotherapy and brachytherapy. [PDF]
, 2004 We present the details of a new linear array dosimeter consisting of a chain of semiconductors mounted on an ultra-thin (50 μm thick) flexible substrate and housed in an intracavitary catheter. The semiconductors, manufactured by NMRC Cork, have not been
