Pyramid Self-Contrastive Learning for Single-shot Test-time Ultrasound Image Denoising
Jiajing Zhang, Bingze Dai, Xi Zhang +2
The inherent electronic and speckle noise complicates clinical interpretation of ultrasound images. Conventional denoising methods rely on explicit noise assumptions whose validity…
2D Sparse Array Design via Reweighted L1 Second Order Cone Programming for 3D Ultrasound Imaging
Xi Zhang, Miguel Bernal, Wei-Ning Lee
Two-dimensional (2D) fully-addressed arrays can conveniently realize three-dimensional (3D) ultrasound imaging while fully controlled such arrays usually demands thousands of indep…
Volumetric Ultrasound via 3D Null Subtraction Imaging with Circular and Spiral Apertures
Bingze Dai, Xi Zhang, Wei-Ning Lee
Volumetric ultrasound imaging faces a fundamental trade-off among image quality, frame rate, and hardware complexity. This study introduces three-dimensional Null Subtraction Imagi…
A Novel Training Framework for Physics-informed Neural Networks: Towards Real-time Applications in Ultrafast Ultrasound Blood Flow Imaging
Haotian Guan, Jinping Dong, Wei-Ning Lee
Ultrafast ultrasound blood flow imaging is a state-of-the-art technique for depiction of complex blood flow dynamics in vivo through thousands of full-view image data (or, timestam…
