Learning-based Linear Inversion for Quantitative Pulse-Echo Speed-of-Sound Imaging
Parisa Salemi Yolgunlu, Jules Blom, Naiara Korta Martiartu +1
Computed ultrasound tomography in echo mode generates maps of tissue speed of sound (SoS) from the shift of echoes when detected under varying steering angles. It solves a lineariz…

Self-Portrait of the Focusing Process in Speckle: II. Gouy Phase Shift for Defocus Correction and Pixel Depth Reassignment
Flavien Bureau, Emma Brenner, Naiara Korta Martiartu +7
This is the second article in a series of three dealing with the exploitation of speckle for aberration correction and reverberation compensation in reflection imaging. When probin…

On the phase aberration estimation using common mid-angle correlations
Naiara Korta Martiartu, Michael Jaeger
Phase aberrations, despite degrading ultrasound images, also encode valuable information about the spatial distribution of the speed of sound in tissue. In pulse-echo ultrasound, w…
