A Cross-Machine Comparison of Shear-Wave Speed Measurements Using 2D Shear-Wave Elastography in the Normal Female Breast
(MDPI, 2021-10-01)
<jats:p>Quantitative measures of radiation-induced breast stiffness are required to support clinical studies of novel breast radiotherapy regimens and exploration of personalised therapy, however, variation between shear-wave ...
Evaluation of Performance Tradeoffs When Using Mechanically Swept 1-D Linear Arrays for 3-D DCE-US.
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2023-07-01)
Dynamic contrast-enhanced ultrasound imaging (DCE-US) may be used to characterize tumor vascular perfusion using metrics derived from time-amplitude curves (TACs). The 3-D DCE-US enables generation of 3-D parametric maps ...
Preclinical Three-Dimensional Vibrational Shear Wave Elastography for Mapping of Tumour Biomechanical Properties In Vivo.
(MDPI, 2022-10-03)
Preclinical investigation of the biomechanical properties of tissues and their treatment-induced changes are essential to support drug-discovery, clinical translation of biomarkers of treatment response, and studies of ...
Multi-Channel Optical Coherence Elastography Using Relative and Absolute Shear-Wave Time of Flight.
(PUBLIC LIBRARY SCIENCE, 2017-01-20)
Elastography, the imaging of elastic properties of soft tissues, is well developed for macroscopic clinical imaging of soft tissues and can provide useful information about various pathological processes which is complementary ...
Ultrasound Tomography Evaluation of Breast Density: A Comparison With Noncontrast Magnetic Resonance Imaging.
(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 ...
Rapid scanning wide-field clutter elimination in epi-optoacoustic imaging using comb LOVIT.
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018-06-01)
Epi-style optoacoustic (OA) imaging provides flexibility by integrating the irradiation optics and ultrasound receiver, yet clutter generated by optical absorption near the probe obscures deep OA sources. Localised vibration ...
In Vivo Validation of Elekta's Clarity Autoscan for Ultrasound-based Intrafraction Motion Estimation of the Prostate During Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-11-15)
PURPOSE: Our purpose was to perform an in vivo validation of ultrasound imaging for intrafraction motion estimation using the Elekta Clarity Autoscan system during prostate radiation therapy. The study was conducted as ...
Validation of the Vectra XT three-dimensional imaging system for measuring breast volume and symmetry following oncological reconstruction.
(SPRINGER, 2018-09-01)
PURPOSE: Three-dimensional surface imaging (3D-SI) of the breasts enables the measurement of breast volume and shape symmetry. If these measurements were sufficiently accurate and repeatable, they could be used in planning ...
Detecting human melanoma cell re-differentiation following BRAF or heat shock protein 90 inhibition using photoacoustic and magnetic resonance imaging.
(NATURE PUBLISHING GROUP, 2017-08-15)
Targeted therapies specific to the BRAF-MEK-ERK signaling pathway have shown great promise in the treatment of malignant melanoma in the last few years, with these drugs now commonly used in clinic. Melanoma cells treated ...
Value of combining dynamic contrast enhanced ultrasound and optoacoustic tomography for hypoxia imaging.
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2017-12-01)
Optoacoustic imaging (OAI) can detect haemoglobin and assess its oxygenation. However, the lack of a haemoglobin signal need not indicate a lack of perfusion. This study uses a novel method to assist the co-registration ...
