Combined Ultrasound Speckle Pattern Similarity Measures
نویسندگان
چکیده
We present an enhanced block matching approach to improve displacement accuracy in ultrasound sequences using a combination of matching measures. The first measure uses the normalised cross correlation for regions of strong signal and the second measure CD , specifically for regions of speckle determined by the speckle signal to noise ratio. We also show displacement field results for simulated speckle and in vitro data.

Ultrasound Specific Similarity Measures for Three-Dimensional Mosaicing
The introduction of 2D array ultrasound transducers enables the instantaneous acquisition of ultrasound volumes in the clinical practice. The next step coming along is the combination of several scans to create compounded volumes that provide an extended field-of-view, so called mosaics. The correct alignment of multiple images, which is a complex task, forms the basis of mosaicing. Especially ...
متن کاملTexture Feature Classification of Liver Sonography Using Fuzzy Similarity Measures
It is difficult to differentiate diffuse liver diseases, namely cirrhotic and fatty livers from normal one by visual inspection from the ultrasound images. The need for computerized tissue characterization is thus justified to assist quantitatively the sonographer for accurate differentiation. In this paper a novel approach of tissue characterization using pattern recognition techniques is deve...
متن کاملUltrasound Speckle Tracking For Strain Estimation
This paper presents an alternative to Elastography by speckle tracking ultrasonic frames quantifying both motion and strain. We combine two similarity measures for varying echographic content including displacement processing, with interframe and trajectory performance measured on extensive synthetic and in vitro data.
متن کاملFluid Registration of Ultrasound using Multi-scale Phase Estimates
We consider the registration of successive images over a cardiac ultrasound sequence. A key challenge is speckle. We suggest that, for practical purposes, speckle should be regarded as the sum of two components: the useful, temporally correlated speckle pattern; and speckle noise, which is the unpredictable change in the speckle pattern. We also propose that an increase in robustness can be obt...
متن کاملAcousto-electrical speckle pattern in Lorentz force electrical impedance tomography.
Ultrasound speckle is a granular texture pattern appearing in ultrasound imaging. It can be used to distinguish tissues and identify pathologies. Lorentz force electrical impedance tomography is an ultrasound-based medical imaging technique of the tissue electrical conductivity. It is based on the application of an ultrasound wave in a medium placed in a magnetic field and on the measurement of...
