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 ... -
Geometric and dosimetric evaluation of the differences between rigid and deformable registration to assess interfraction motion during pelvic radiotherapy.
White, I; McQuaid, D; McNair, H; Dunlop, A; Court, S; et al. (ELSEVIER, 2019-03-29)BACKGROUND AND PURPOSE: Appropriate internal margins are essential to avoid a geographical miss in intensity-modulated radiation therapy (IMRT) for endometrial cancer (EC). This study evaluated interfraction target motion ... -
Magnetic resonance image guided adaptive radiotherapy for gynaecological and rectal cancer
Dearnaley, D; White, I (Institute of Cancer Research (University Of London), 2020-11-30)Multiple challenges exist in radiotherapy for gynaecological and rectal cancer. These lead to uncertainty and error in dose delivered to the tumour target and organs at risk (OARs). Adequate planning target volume (PTV) ... -
Next Generation Sequencing Assay for Detection of Circulating HPV DNA (cHPV-DNA) in Patients Undergoing Radical (Chemo)Radiotherapy in Anal Squamous Cell Carcinoma (ASCC).
Lee, JY; Cutts, RJ; White, I; Augustin, Y; Garcia-Murillas, I; et al. (FRONTIERS MEDIA SA, 2020-04-17)Background: Following chemo-radiotherapy (CRT) for human papilloma virus positive (HPV+) anal squamous cell carcinoma (ASCC), detection of residual/recurrent disease is challenging. Patients frequently undergo unnecessary ... -
Realizing the potential of magnetic resonance image guided radiotherapy in gynaecological and rectal cancer.
White, IM; Scurr, E; Wetscherek, A; Brown, G; Sohaib, A; et al. (BRITISH INST RADIOLOGY, 2019-05-14)CT-based radiotherapy workflow is limited by poor soft tissue definition in the pelvis and reliance on rigid registration methods. Current image-guided radiotherapy and adaptive radiotherapy models therefore have limited ... -
The Stacked-Ellipse Algorithm: An Ultrasound-Based 3-D Uterine Segmentation Tool for Enabling Adaptive Radiotherapy for Uterine Cervix Cancer.
Mason, SA; White, IM; Lalondrelle, S; Bamber, JC; Harris, EJ (ELSEVIER SCIENCE INC, 2020-04-01)The stacked-ellipse (SE) algorithm was developed to rapidly segment the uterus on 3-D ultrasound (US) for the purpose of enabling US-guided adaptive radiotherapy (RT) for uterine cervix cancer patients. The algorithm was ... -
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 ...
