Denoising Plane Wave Ultrasound Images Using Diffusion Probabilistic Models
Hojat Asgariandehkordi, Sobhan Goudarzi, Mostafa Sharifzadeh +2
Ultrasound plane wave imaging is a cutting-edge technique that enables high frame-rate imaging. However, one challenge associated with high frame-rate ultrasound imaging is the hig…
Mitigating Aberration-Induced Noise: A Deep Learning-Based Aberration-to-Aberration Approach
Mostafa Sharifzadeh, Sobhan Goudarzi, An Tang +2
One of the primary sources of suboptimal image quality in ultrasound imaging is phase aberration. It is caused by spatial changes in sound speed over a heterogeneous medium, which…
Deep Ultrasound Denoising Using Diffusion Probabilistic Models
Hojat Asgariandehkordi, Sobhan Goudarzi, Adrian Basarab +1
Ultrasound images are widespread in medical diagnosis for musculoskeletal, cardiac, and obstetrical imaging due to the efficiency and non-invasiveness of the acquisition methodolog…
Inverse Problem of Ultrasound Beamforming with Denoising-Based Regularized Solutions
Sobhan Goudarzi, Adrian Basarab, Hassan Rivaz
During the past few years, inverse problem formulations of ultrasound beamforming have attracted a growing interest. They usually pose beamforming as a minimization problem of a fi…
Deep Ultrasound Denoising Without Clean Data
Sobhan Goudarzi, Hassan Rivaz
On one hand, the transmitted ultrasound beam gets attenuated as propagates through the tissue. On the other hand, the received Radio-Frequency (RF) data contains an additive Gaussi…
A Unifying Approach to Inverse Problems of Ultrasound Beamforming and Deconvolution
Sobhan Goudarzi, Adrian Basarab, Hassan Rivaz
Beamforming is an essential step in the ultrasound image formation pipeline and has recently attracted growing interest. An important goal of beamforming is to increase the image s…
Plane-Wave Ultrasound Beamforming: A Deep Learning Approach
Sobhan Goudarzi, Hassan Rivaz
Medical ultrasound provides images which are the spatial map of the tissue echogenicity. Unfortunately, an ultrasound image is a low-quality version of the expected Tissue Reflecti…
Plane-Wave Ultrasound Beamforming Through Independent Component Analysis
Sobhan Goudarzi, Amir Asif, Hassan Rivaz
Beamforming in plane-wave imaging (PWI) is an essential step in creating images with optimal quality. Adaptive methods estimate the apodization weights from echo traces acquired by…
