Quantitative sonoelastography for the in vivo assessment of skeletal muscle viscoelasticity.
A novel quantitative sonoelastography technique for assessing the viscoelastic properties of skeletal muscle tissue was developed. Slowly propagating shear wave interference patterns (termed crawling waves) were generated using a two-source configuration vibrating normal to the surface. Theoretical models predict crawling wave displacement fields, which were validated through phantom studies. I...
متن کاملMuscle Tissue Characterization Using Quantitative Sonoelastography: Preliminary Results
A quantitative sonoelastographic technique for skeletal muscle tissue characterization is introduced. Experimental data was collected in both ex vivo bovine and in vivo human skeletal muscle tissue. Crawling wave sonoelastographic data was processed using a quantitative technique for estimating local shear wave speed distributions. Results on ex vivo skeletal muscle samples demonstrate shear wa...
متن کاملQuantitative Assessment of Muscle Fatigue for FES Research Studies
Background: Muscle fatigue is an important issue in neuromuscular rehabilitation. Better control of this phenomenon would result in better prevention of its consequent physiological damages.Objective: To provide a mathematical representation of muscle fatigue as a function of time.Methods: We conducted this study by combining the EMG-based estimation methods of muscle activation with the availa...
متن کاملQuantitative crawling wave sonoelastography of benign and malignant thyroid nodules.
OBJECTIVE The purpose of this study is to determine if crawling wave elastography, a novel sonoelastography technique, can be used to provide quantitative measurements of thyroid tissue shear velocity (a measure of tissue stiffness) and distinguish between benign and malignant thyroid nodules. STUDY DESIGN Diagnostic test assessment. SETTING Academic university. SUBJECTS AND METHODS Fresh...
متن کاملQuantitative model for predicting lymph formation and muscle compressibility in skeletal muscle during contraction and stretch.
Skeletal muscle is widely perceived as nearly incompressible despite the fact that blood and lymphatic vessels within the endomysial and perimysial spaces undergo significant changes in diameter and length during stretch and contraction. These fluid shifts between fascicle and interstitial compartments have proved extremely difficult to measure. In this paper, we propose a theoretical framework...
