Magnetic-resonance imaging techniques for detection of elasticity variation
Medical Physics, 1995The relative success of manual palpation in the detection of breast cancer would suggest that a method for remote palpation resulting in a measurement of tissue elasticity could provide a diagnostic tool for detecting cancerous lesions deeper within the breast.

Elasticity and Viscoelasticity Imaging Based on Small Particles Exposed to External Forces
Processes, 2023 Particle-mediated elasticity/viscoelasticity imaging has the potential to expand the elasticity imaging field, as it can provide accurate and local tissue elastic properties as well as density and viscosity. Here, we investigated elasticity imaging based

Techniques for elastic imaging: a review
IEEE Engineering in Medicine and Biology Magazine, 1996In this article the authors review imaging techniques for assessing the elastic properties of tissue. They briefly look at the fundamental techniques in the above-mentioned fields and then present elastography techniques developed by current research groups. The authors' review is focused on published papers in the archival literature.

A New Technique For Elastic Registration Of Tomographic Images
SPIE Proceedings, 1988A simple algorithm for geometric registration of tomographic images was developed to be applied to images of the heart obtained by Positron Emission Tomography (PET). Commonly, image misregistrations are not only caused by simple positioning differences like translation and rotation, but also by deformations that cannot be expressed by simple geometric

Investigation of parametric spectral estimation techniques for elasticity imaging
Ultrasound in Medicine & Biology, 2005Several autoregressive (AR) and autoregressive moving average (ARMA) parametric spectral estimators were evaluated for use in tissue strain estimation. Using both 1-D simulations and in vitro phantom experiments, the performance of these parametric spectral strain estimators were compared against both a nonparametric discrete Fourier transform (DFT ...

Spectral strain estimation techniques for tissue elasticity imaging
2021This research project examines the applicability of novel spectral domain strain estimation algorithms to improve the clinical value of tissue elasticity images. Pathological changes can be frequently correlated to changes in soft tissue stiffness. Despite the fact that many cancers, including those found in the breast and prostate, often manifest ...

Dynamic elastic image stretching technique applied to thermographic images
IEE Proceedings I Communications, Speech and Vision, 1990A method of automatically ‘stretching’ a series of hand thermograms to a standard form is described. It is based on an elastic model which has the iterative and co-operative properties of relaxation labelling, while not requiring large storage space for label updating.

Improved contralateral subtraction images by use of elastic matching technique
Medical Physics, 2000A contralateral subtraction technique has been developed to assist radiologists in the detection of asymmetric abnormalities such as lung nodules on a single chest radiograph. With this technique, a contralateral subtraction image is obtained by subtracting a right/left reversed “mirror” image from the original one. The lesions in the subtraction image

Ultrasound in Medicine & Biology, 2021
Our purpose was to compare the diagnostic performances of strain elastography (SE) and shear-wave elastography (SWE) in differentiating breast lesions by combining with conventional ultrasound (US). A total of 198 patients with 203 breast lesions underwent conventional US, SE and SWE examination using MyLab 90 and Aixplorer US systems.
