Dynamic Ultrasound Beamforming Using Left-to-Right Arithmetic Adders on FPGA

Muhammad Usman, Shujaat Khan, Dorit Merhof

Adder trees are the computational backbone of delay-and-sum (DAS) ultrasound beamforming, where their implementation directly determines the energy, throughput, and area of a real-…

Blind Ultrasound Image Enhancement via Self-Supervised Physics-Guided Degradation Modeling

Shujaat Khan, Syed Muhammad Atif, Jaeyoung Huh +1

Ultrasound (US) interpretation is hampered by multiplicative speckle, acquisition blur from the point-spread function (PSF), and scanner- and operator-dependent artifacts. Supervis…
