GPU-Based Elasticity Imaging Algorithms
Quasi-static elastography involves estimating the displacement field of the tissue undergoing slow compression. Since elastography is computationally expensive, many compromises have been made to perform it in real time. Parallelized algorithms and implementations for freehand palpation elastography are proposed in this paper to speed the computation. We present parallel implementations for Nor...
متن کاملAcoustic radiation force-based elasticity imaging methods.
Conventional diagnostic ultrasound images portray differences in the acoustic properties of soft tissues, whereas ultrasound-based elasticity images portray differences in the elastic properties of soft tissues (i.e. stiffness, viscosity). The benefit of elasticity imaging lies in the fact that many soft tissues can share similar ultrasonic echogenicities, but may have different mechanical prop...
متن کاملModel-Based Reconstructive Elasticity Imaging Using Ultrasound
Elasticity imaging is a reconstructive imaging technique where tissue motion in response to mechanical excitation is measured using modern imaging systems, and the estimated displacements are then used to reconstruct the spatial distribution of Young's modulus. Here we present an ultrasound elasticity imaging method that utilizes the model-based technique for Young's modulus reconstruction. Bas...
متن کاملElasticity Imaging
Basic principles and examples of elasticity imaging aresummarized. The chapter focuses on static ultrasonicmethods, and it discusses the advantages and limitationsof this approach in the context of dynamic methods andalternative imaging modalities from the literature. We re-view the physics of continuum deformations as a way toevaluate various experimental approaches. A ...
متن کاملQuo vadis elasticity imaging?
In the past decade, an important field that has emerged as complementary to ultrasonic imaging is that of elasticity imaging. The term encompasses a variety of techniques that can depict a mechanical response or property of tissues. In ultrasound, its premise is built on two important facts: (a) that significant differences between mechanical properties of several tissue components exist and (b...
