Short-Acquisition Contrast-Free Super-Resolution Microvascular Imaging in Rabbit Kidney

Zhengchang Kou, Yuning Zhao, Mingrui Liu +2

Ultrasound localization microscopy (ULM) enables micrometer-scale microvascular imaging by localizing and tracking intravascular microbubbles, but its dependence on exogenous contr…

Label-free super-resolution color flow imaging using ultrasound phase microscopy

Zhengchang Kou, Junhang Zhang, Chen Gong +8

Ultrasound vascular imaging is limited by acoustic diffraction, restricting visualization of microvessels essential for understanding organ function and disease. Label-free super-r…

A Radiological Clip Design Using Ultrasound Identification to Improve Localization

Jenna Cario, Zhengchang Kou, Rita J. Miller +3

Objective: We demonstrate the use of ultrasound to receive an acoustic signal transmitted from a radiological clip designed from a custom circuit. This signal encodes an identifica…

High-resolution Power Doppler Using Null Subtraction Imaging

Zhengchang Kou, Matthew Lowerison, Qi You +3

To improve the spatial resolution of power Doppler (PD) imaging, we explored null subtraction imaging (NSI) as an alternative beamforming technique to delay-and-sum (DAS). NSI is a…

Grating lobe reduction in plane wave imaging with angular compounding using subtraction of coherent signals

Zhengchang Kou, Rita J. Miller, Michael L. Oelze

Plane wave imaging (PWI) with angular compounding has gained in popularity over recent years because it provides high frame rates and good image properties. However, most linear ar…

Through Tissue Ultra-high-definition Video Transmission Using an Ultrasound Communication Channel

Zhengchang Kou, Andrew C. Singer, Michael L. Oelze

Wireless capsule endoscopy (WCE) has been widely adopted as complementary to traditional wired gastroendoscopy, especially for small bowel diseases which are beyond the latter's re…
