Gold nanorod reshaping in vitro and in vivo using a continuous wave laser.
(PUBLIC LIBRARY SCIENCE, 2017-10-18)
Gold nanorods (GNRs) are increasingly being investigated for cancer theranostics as they possess features which lend themselves in equal measures as contrast agents and catalysts for photothermal therapy. Their optical ...
Temporal regularization of ultrasound-based liver motion estimation for image-guided radiation therapy.
(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 ...
Investigation of In Vivo skin stiffness anisotropy in breast cancer related lymphoedema.
(ELSEVIER SCI LTD, 2016-01-04)
There is a limited range of suitable measurement techniques for detecting and assessing breast cancer related lymphoedema (BCRL). This study investigated the suitability of using skin stiffness measurements, with a particular ...
Optically and acoustically triggerable sub-micron phase-change contrast agents for enhanced photoacoustic and ultrasound imaging.
(ELSEVIER GMBH, 2017-06-01)
We demonstrate a versatile phase-change sub-micron contrast agent providing three modes of contrast enhancement: 1) photoacoustic imaging contrast, 2) ultrasound contrast with optical activation, and 3) ultrasound contrast ...
Towards ultrasound-guided adaptive radiotherapy for cervical cancer: Evaluation of Elekta's semiautomated uterine segmentation method on 3D ultrasound images.
(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 ...
Non-coplanar trajectories to improve organ at risk sparing in volumetric modulated arc therapy for primary brain tumors.
(ELSEVIER IRELAND LTD, 2016-10-01)
BACKGROUND AND PURPOSE: To evaluate non-coplanar volumetric modulated arc radiotherapy (VMAT) trajectories for organ at risk (OAR) sparing in primary brain tumor radiotherapy. MATERIALS AND METHODS: Fifteen patients were ...
Ultrasonic Sound Speed Estimation for Liver Fat Quantification: A Review by the AIUM-RSNA QIBA Pulse-Echo Quantitative Ultrasound Initiative.
(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 ...
High frequency ultrasound vibrational shear wave elastography for preclinical research.
(IOP Publishing Ltd, 2022-12-07)
Preclinical evaluation of novel therapies using models of cancer is an important tool in cancer research, where imaging can provide non-invasive tools to characterise the internal structure and function of tumours. The ...
Investigating the contribution of hyaluronan to the breast tumour microenvironment using multiparametric MRI and MR elastography.
(WILEY, 2023-06-01)
Hyaluronan (HA) is a key component of the dense extracellular matrix in breast cancer, and its accumulation is associated with poor prognosis and metastasis. Pegvorhyaluronidase alfa (PEGPH20) enzymatically degrades HA and ...
Ultrasound Measurement of Local Deformation in the Human Free Achilles Tendon Produced by Dynamic Muscle-Induced Loading: A Systematic Review.
(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 ...
