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…
Calibrating Data Mismatches in Deep Learning-Based Quantitative Ultrasound Using Setting Transfer Functions
Ufuk Soylu, Michael L. Oelze
Deep learning (DL) can fail when there are data mismatches between training and testing data. Due to its operator-dependent nature, acquisition-related data mismatches, caused by d…
