In transabdominal histotripsy, ultrasound pulses are focused into the body to noninvasively
destroy soft tissues via cavitation. However, the ability to focus is limited by phase …

Abdominal ultrasound image quality is hampered by phase aberration, that is mainly caused
by the large speed-of-sound (SoS) differences between fat and muscle tissue in the …

Echo imaging in ultrasound computed tomography (USCT) using the synthetic aperture
technique is performed with the assumption that the speed of sound is constant in the …

Purpose The conventional medical ultrasound imaging has a low lateral spatial resolution,
and the image quality depends on the depth of the imaging location. To overcome these …

Degradation of image quality caused by aberrations and off-axis interferences is common in
medical ultrasound imaging. The ring-array echo imaging also suffers from these …

Despite the promising clinical application of linear-array photoacoustic tomography, it has
been shown the variable speed of sound would severely affect the photoacoustic imaging …

Bent-ray reconstruction method can improve sound speed image quality, compared with
straight-ray reconstruction. However, it suffers from time-consuming ray-linking iteration …

In this study, we propose a multi-stencils fast marching method to solve the factored eikonal
equations for media with quadratic anisotropy, also known as Riemannian anisotropy …

We consider ultrasound waveform tomography using an ultrasound prototype equipped with
the ring-array transducers. For this purpose, we use robust contrast source inversion (robust …

In Ultrasound computer tomography (USCT) Synthetic aperture focusing technique (SAFT) is
often applied for reflectivity image reconstruction. Phase aberration correction is essential to …
