Combined Ultrasound and Cone Beam CT Improves Target Segmentation for Image Guided Radiation Therapy in Uterine Cervix Cancer.
Mason, SA; White, IM; O'Shea, T; McNair, HA; Alexander, S; et al. (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 ... -
Magnitude of observer error using cone beam CT for prostate interfraction motion estimation: effect of reducing scan length or increasing exposure.
McNair, HA; Harris, EJ; Hansen, VN; Thomas, K; South, C; et al. (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 ... -
Towards ultrasound-guided adaptive radiotherapy for cervical cancer: Evaluation of Elekta's semiautomated uterine segmentation method on 3D ultrasound images.
Mason, SA; O'Shea, TP; White, IM; Lalondrelle, S; Downey, K; et al. (WILEY, 2017-07-01)PURPOSE: 3D ultrasound (US) images of the uterus may be used to adapt radiotherapy (RT) for cervical cancer patients based on changes in daily anatomy. This requires accurate on-line segmentation of the uterus. The aim of ...
