, 50kw High Freque
It compares pros and cons of various measurement techniques, encompassing conventional methods new indentation methods of measurement, such as nanoindentation, suction measurement, indirect methods, elasticity imaging
, modeling of tissue nonlinearity and viscoelasticity, and finite element methods.
4] introduced shear wave elasticity imaging
(SWEI) for noninvasive diagnosis of changes in tissue mechanical properties.
Most of the reported elastography techniques focus currently on three fields: (l) Optimization methods in elasticity imaging
; (2) Freehand palpation elasticity imaging
; and (3) Real-time elasticity imaging
Artann's technologies include bone ultrasonometry, colonoscopy force monitor, mechanical imaging, breast mechanical imaging, prostate mechanical imaging, vaginal tactile imager, shear wave elasticity imaging
, temperature profile spectroscopy, droplet, body hydration monitor, and time reversal acoustics.
Thirteen contributed chapters begin with the fundamentals, addressing multiwave imaging to elasticity imaging
, and speckle interferometry and nonlinear methods.
This article will review the physics behind the elastographic technique, the utility of elasticity imaging
in clinical practice, the implications of EI on patient care, and possible advances in elastography in the near future.
Overall, elasticity imaging
increases the specificity of ultrasound by measuring the compressibility and mechanical properties of a lesion.
Applications include cardiovascular elasticity imaging
, harmonic motion imaging in high intensity focused ultrasound (as used in breast cancer detection, and characterization of skeletal muscle elasticity using magnetic resonance elastography.
1 Elasticity Imaging
May Reduce the Need for Breast Biopsy
Using elasticity imaging
, researchers correctly identified both cancerous and harmless lesions in nearly all of the cases studied.
Using a real-time, free-hand elasticity imaging
technique along with a routine ultrasound exam, Dr.
