The feasibility of subharmonic contrast intravascular ultrasound (IVUS) imaging was
investigated using a prototype nonlinear IVUS system and the commercial contrast agent …

Objective: We sought to investigate feasibility of vasa vasorum imaging using the novel
technique of contrast harmonic intravascular ultrasound. Methods: Prototype intravascular …

Nonlinear contrast agent imaging with intravascular ultrasound (IVUS) is investigated using
a prototype IVUS system and an experimental small bubble contrast agent. The IVUS system …

Purpose: Subharmonic intravascular ultrasound imaging (S‐IVUS) could visualize the
adventitialvasa vasorum, but the high pressure threshold required to incite subharmonic …

We demonstrate two methods for vasa vasorum imaging using contrast-enhanced
intravascular ultrasound, which can be performed using commercial catheters. Plaque …

OBJECTIVE: To demonstrate the feasibility of simultaneous dual fundamental grayscale and
subharmonic imaging on a modified commercial scanner. MOTIVATION: The ability to …

Recent studies have shown the feasibility of tissue and contrast harmonic imaging with a
prototype nonlinear intravascular ultrasound (IVUS) system using a conventional single …

RATIONALE AND OBJECTIVES: Although contrast-enhanced ultrasound imaging
techniques such as harmonic imaging (HI) have evolved to reduce tissue signals using the …

Tissue harmonic imaging (THI) has been shown to increase image quality of medical
ultrasound in the frequency range from 2 to 10 MHz and might, therefore, also be used to …

The application of ultrasound contrast agents aims to detect low velocity blood flow in the
microcirculation. To enhance discrimination between tissue and blood containing the …
