Review of ultrasound image guidance in external beam radiotherapy part II: intra-fraction motion management and novel applications.
O'Shea, T; Bamber, J; Fontanarosa, D; van der Meer, S; Verhaegen, F; et al. (IOP PUBLISHING LTD, 2016-04-21)Imaging has become an essential tool in modern radiotherapy (RT), being used to plan dose delivery prior to treatment and verify target position before and during treatment. Ultrasound (US) imaging is cost-effective in ... -
Temporal regularization of ultrasound-based liver motion estimation for image-guided radiation therapy.
O'Shea, TP; Bamber, JC; Harris, EJ (WILEY, 2016-01-01)PURPOSE: Ultrasound-based motion estimation is an expanding subfield of image-guided radiation therapy. Although ultrasound can detect tissue motion that is a fraction of a millimeter, its accuracy is variable. For controlling ... -

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 ... -
Theranostic Attributes of Acoustic Cluster Therapy and Its Use for Enhancing the Effectiveness of Liposomal Doxorubicin Treatment of Human Triple Negative Breast Cancer in Mice.
Bush, N; Healey, A; Shah, A; Box, G; Kirkin, V; et al. (FRONTIERS MEDIA SA, 2020-02-20)INTRODUCTION: Acoustic cluster therapy (ACT) comprises co-administration of a formulation containing microbubble/microdroplet clusters (PS101), together with a regular medicinal drug (e.g., a chemotherapeutic) and local ... -
Therapeutic Dose Response of Acoustic Cluster Therapy in Combination With Irinotecan for the Treatment of Human Colon Cancer in Mice.
Bush, N; Healey, A; Shah, A; Box, G; Kirkin, V; et al. (FRONTIERS MEDIA SA, 2019-11-19)Introduction: Acoustic Cluster Therapy (ACT) comprises coadministration of a formulation containing microbubble-microdroplet clusters (PS101) together with a regular medicinal drug and local ultrasound (US) insonation of ... -
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 ... -
Ultrasonic Sound Speed Estimation for Liver Fat Quantification: A Review by the AIUM-RSNA QIBA Pulse-Echo Quantitative Ultrasound Initiative.
Wang, X; Bamber, JC; Esquivel-Sirvent, R; Ormachea, J; Sidhu, PS; et al. (ELSEVIER SCIENCE INC, 2023-08-05)Non-alcoholic fatty liver disease (NAFLD) is a significant cause of diffuse liver disease, morbidity and mortality worldwide. Early and accurate diagnosis of NALFD is critical to identify patients at risk of disease ... -
Ultrasound Measurement of Local Deformation in the Human Free Achilles Tendon Produced by Dynamic Muscle-Induced Loading: A Systematic Review.
Shivapatham, G; Richards, S; Bamber, J; Screen, H; Morrissey, D (ELSEVIER SCIENCE INC, 2023-07-01)Achilles tendinopathy is the most prevalent lower limb tendinopathy, yet it remains poorly understood, with mismatches between observed structure and reported function. Recent studies have hypothesised that Achilles tendon ... -
Ultrasound Tomography Evaluation of Breast Density: A Comparison With Noncontrast Magnetic Resonance Imaging.
OʼFlynn, EAM; Fromageau, J; Ledger, AE; Messa, A; DʼAquino, A; et al. (LIPPINCOTT WILLIAMS & WILKINS, 2017-06-01)OBJECTIVES: Ultrasound tomography (UST) is an emerging whole-breast 3-dimensional imaging technique that obtains quantitative tomograms of speed of sound of the entire breast. The imaged parameter is the speed of sound ... -
