Does breast composition influence late adverse effects in breast radiotherapy?
(CHURCHILL LIVINGSTONE, 2016-04-01)
BACKGROUND: Large breast size is associated with increased risk of late adverse effects after surgery and radiotherapy for early breast cancer. It is hypothesised that effects of radiotherapy on adipose tissue are responsible ...
A multicentre study of the evidence for customized margins in photon breast boost radiotherapy.
(BRITISH INST RADIOLOGY, 2016-01-01)
OBJECTIVE: To determine if subsets of patients may benefit from smaller or larger margins when using laser setup and bony anatomy verification of breast tumour bed (TB) boost radiotherapy (RT). METHODS: Verification imaging ...
Combined Ultrasound and Cone Beam CT Improves Target Segmentation for Image Guided Radiation Therapy in Uterine Cervix Cancer.
(ELSEVIER SCIENCE INC, 2019-07-01)
PURPOSE: Adaptive radiation therapy strategies could account for interfractional uterine motion observed in patients with cervix cancer, but the current cone beam computed tomography (CBCT)-based treatment workflow is ...
Classification of fibroglandular tissue distribution in the breast based on radiotherapy planning CT.
(BIOMED CENTRAL LTD, 2016-01-14)
BACKGROUND: Accurate segmentation of breast tissues is required for a number of applications such as model based deformable registration in breast radiotherapy. The accuracy of breast tissue segmentation is affected by the ...
Magnitude of observer error using cone beam CT for prostate interfraction motion estimation: effect of reducing scan length or increasing exposure.
(BRITISH INST RADIOLOGY, 2015-10-01)
OBJECTIVE: Cone beam CT (CBCT) enables soft-tissue registration to planning CT for position verification in radiotherapy. The aim of this study was to determine the interobserver error (IOE) in prostate position verification ...
Real-time intrafraction motion monitoring in external beam radiotherapy.
(IOP PUBLISHING LTD, 2019-08-07)
Radiotherapy (RT) aims to deliver a spatially conformal dose of radiation to tumours while maximizing the dose sparing to healthy tissues. However, the internal patient anatomy is constantly moving due to respiratory, ...
