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

Risk-adapted targeted intraoperative radiotherapy versus whole-breast radiotherapy for breast cancer:5-year results for local control and overall survival from the TARGIT-a randomised trial [PDF]

, 2014
Background: The TARGIT-A trial compared risk-adapted radiotherapy using single-dose targeted intraoperative radiotherapy (TARGIT) versus fractionated external beam radiotherapy (EBRT) for breast cancer.

Dose agreement analysis of treatment planning system-calculated doses and markus chamber-measured doses in the near-surface region for breast cancer patients' conformal treatment plans

Journal of Medical Physics, 2022
Background: Surface/skin dose measurement is one of the most challenging tasks for clinical dosimetry in radiotherapy and comparison with almost all the commercially available treatment planning systems (TPSs) brings a significant variation with the ...

Different meaning of the mean heart dose between 3D-CRT and IMRT for breast cancer radiotherapy

Frontiers in Oncology, 2023
BackgroundPrevious studies in 2D and in 3D conformal radiotherapy concludes that the maximal heart distance and the mean heart dose (MHD) are considered predictive of late cardiac toxicities.
