Spectral strain estimation techniques for tissue elasticity imaging

2021
This 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 ...

Techniques for elastic imaging: a review

IEEE Engineering in Medicine and Biology Magazine, 1996
In 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.

Dynamic elastic image stretching technique applied to thermographic images

IEE Proceedings I Communications, Speech and Vision, 1990
A 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.

Investigation of parametric spectral estimation techniques for elasticity imaging

Ultrasound in Medicine & Biology, 2005
Several 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 ...

Magnetic‐resonance imaging techniques for detection of elasticity variation

Medical Physics, 1995
The 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.

Improved contralateral subtraction images by use of elastic matching technique

Medical Physics, 2000
A 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
