Automated Compression Device for Viscoelasticity Imaging
Such a device should be lightweight, portable and easy to use for patient studies to capture tissue dynamics under external stress. We present the design of an automated compression device for studying the creep response of materials with tissue-like behaviors.... Read more

Automated In Vivo Sub-Hertz Analysis of Viscoelasticity (SAVE) for Evaluation of Breast Lesions
Many breast tumors found by palpation manifest as stiff masses. The stiffness of tumor is related to a mechanical property known as elasticity. Elastography methods use tissue elasticity as a biomarker to provide invaluable information that improves classification of the... Read more

Background Removal and Vessel Filtering of Non-Contrast Ultrasound Images of Microvasculature
Conventional ultrasound Doppler imaging using classic FIR and IIR wall filters prohibits visualization of the small vessels due to strong Fourier spectral overlap between tissue and blood echoes. A clutter removal method is proposed that utilizes spatiotemporal coherence of the... Read more

Unambiguous Identification and Visualization of an Acoustically Active Catheter by Ultrasound Imaging in Real Time: Theory, Algorithm, and Phantom Experiments
Ultrasound-guided navigation of intracardiac catheters during minimally invasive procedures can be challenging due to the inability of B-mode ultrasound to distinguish the distal end of catheter from its body and the surrounding tissue. To better visualize the distal tip and... Read more
