Impact of aperture, depth, and acoustic clutter on performance of Coherent Multi-Transducer Ultrasound imaging
Laura Peralta, Alessandro Ramalli, Michael Reinwald +2
Transducers with larger aperture size are desirable in ultrasound imaging to improve resolution and image quality. A coherent multi-transducer ultrasound imaging system (CoMTUS) en…
Coherent Multi-Transducer Ultrasound Imaging
Laura Peralta, Alberto Gomez, Ying Luan +3
An extended aperture has the potential to greatly improve ultrasound imaging performance. This work extends the effective aperture size by coherently compounding the received radio…
3-D Super-Resolution Ultrasound (SR-US) Imaging using a 2-D Sparse Array with High Volumetric Imaging Rate
S. Harput, K. Christensen-Jeffries, J. Brown +10
Super-resolution ultrasound imaging has been so far achieved in 3-D by mechanically scanning a volume with a linear probe, by co-aligning multiple linear probes, by using multiplex…
3-D Motion Correction for Volumetric Super-Resolution Ultrasound (SR-US) Imaging
S. Harput, K. Christensen-Jeffries, J. Brown +5
Motion during image acquisition can cause image degradation in all medical imaging modalities. This is particularly relevant in 2-D ultrasound imaging, since out-of-plane motion ca…
3-D Super-Resolution Ultrasound (SR-US) Imaging with a 2-D Sparse Array
S. Harput, K. Christensen-Jeffries, A. Ramalli +10
High frame rate 3-D ultrasound imaging technology combined with super-resolution processing method can visualize 3-D microvascular structures by overcoming the diffraction limited…
