Journal ArticleDOI
Relocatable frame for stereotactic external beam radiotherapy.
TL;DR: A non-invasive head fixation system is described which is accurately relocatable and enables the transfer of stereotactic positions between a variety of radiodiagnostic images and therapeutic procedures.
Journal ArticleDOI
Phase III pilot study of dose escalation using conformal radiotherapy in prostate cancer: PSA control and side effects
David P. Dearnaley,Emma Hall,David J. Lawrence,Robert Huddart,Rosalind A. Eeles,Christopher M. Nutting,J. Gadd,A.P. Warrington,M. Bidmead,Alan Horwich +9 more
TL;DR: D dose escalation from 64 to 74 Gy using conformal radiotherapy may improve long-term PSA control, but a treatment margin of 1.5 cm is unnecessary and is associated with increased acute bowel and bladder reactions.
Journal ArticleDOI
Evaluation of the Delta4 phantom for IMRT and VMAT verification.
TL;DR: The Delta(4) diode array phantom was evaluated for verification of segmental intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) on an Elekta linear accelerator and has been introduced into clinical use.
Journal ArticleDOI
Hypofractionated stereotactic radiotherapy in the management of recurrent glioma
Stephen F. Shepherd,Robert W. Laing,Vivian P Cosgrove,Vivian P Cosgrove,A.P. Warrington,A.P. Warrington,F. Hines,Susan Ashley,Michael Brada +8 more
TL;DR: Hypofractionated SRT is a noninvasive, well-tolerated, outpatient-based method of delivering palliative, high-dose, focal irradiation in patients with recurrent glioma.
Journal ArticleDOI
An investigation into the dosimetry of a nine-field tomotherapy irradiation using BANG-gel dosimetry.
Mark Oldham,I B Baustert,C Lord,Timothy Andrew Davies Smith,M McJury,A.P. Warrington,Martin O. Leach,Steve Webb +7 more
TL;DR: The gel dosimeter was found to agree well with predicted dose distributions and accurately measured the steep penumbral fall-off of dose, even after many days, proving its potential for the verification of IMRT distributions.
