Real-time H-scan ultrasound imaging using a Verasonics research scanner

Ultrasonic Shear Wave Elasticity Imaging (SWEI) Sequencing and Data Processing Using a Verasonics Research Scanner

Ultrasound elasticity imaging has been developed over the last decade to estimate tissue stiffness. Shear wave elasticity imaging (SWEI) quantifies tissue stiffness by measuring the speed of propagating shear waves following acoustic radiation force excitation. This work presents the sequencing and data processing protocols of SWEI using a Verasonics system. The selection of the sequence parame...

Speeding-up MR acquisitions using ultrasound signals, and scanner-less real-time MR imaging

Target Audience: Researchers and clinicians interested in real-time MRI and image-guided therapies. Purpose: MRI and ultrasound (US) imaging have complementary properties and advantages, with great soft tissue contrast for the former and high acquisition rates for the latter. For this reason several noteworthy efforts have been made to combine the two imaging modalities. A characteristic of the...

Real-Time Ultrasound Imaging Simulation

This paper introduces UltraSim, a computer-based interactive simulator device designed to train physicians and technicians in medical diagnosis using ultrasound systems. Students using the system are able to learn how to identify and diagnose a wide range of medical cases by operating a simulated ultrasound machine on a mannequin, without any need for actual patients. This application relates t...

Arbitrary Waveform Generation with the Verasonics Research Ultrasound Platform

Spatial Angular Compounding Technique for H-Scan Ultrasound Imaging.

H-Scan is a new ultrasound imaging technique that relies on matching a model of pulse-echo formation to the mathematics of a class of Gaussian-weighted Hermite polynomials. This technique may be beneficial in the measurement of relative scatterer sizes and in cancer therapy, particularly for early response to drug treatment. Because current H-scan techniques use focused ultrasound data acquisit...
