Medical ultrasound images are reconstructed with simplifying assumptions on wave
propagation, with one of the most prominent assumptions being that the imaging medium is …

Medical ultrasound imaging relies heavily on high-quality signal processing to provide
reliable and interpretable image reconstructions. Conventionally, reconstruction algorithms …

Ultrasound is an adjunct tool to mammography that can quickly and safely aid physicians in
diagnosing breast abnormalities. Clinical ultrasound often assumes a constant sound speed …

Ultrasound computed tomography is an inexpensive and radiation-free medical imaging
technique used to quantify the tissue acoustic properties for advanced clinical diagnosis …

Purpose. Due to its safe, low-cost, portable, and real-time nature, ultrasound is a prominent
imaging method in computer-assisted interventions. However, typical B-mode ultrasound …

Ultrasound b-mode imaging is a qualitative approach and diagnostic quality strongly
depends on operators' training and experience. Quantitative approaches can provide …

Most ultrasound imaging techniques necessitate the fundamental step of converting
temporal signals received from transducer elements into a spatial echogenecity map. This …

B-mode imaging is a qualitative method and its interpretation depends on users' experience.
Quantitative tissue information can increase precision and decrease user ambiguity. For …

Speed-of-sound (SoS) is an emerging ultrasound contrast modality, where pulse-echo
techniques using conventional transducers offer multiple benefits. For estimating tissue SoS …

Abstract ℓ-BFGS is the state-of-the-art optimization method for many large scale inverse
problems. It has a small memory footprint and achieves superlinear convergence. The …
