Fast Alternating Radial Beamforming for Speed-of-Sound Imaging Based on Apparent Speckle Shifts
Dieter Schweizer, Can Deniz Bezek, Orcun Goksel
Pulse-echo speed-of-sound (SoS) imaging based on minute misalignments between consecutively acquired ultrasound images traditionally relies on images beamformed on Cartesian grids.…
Image-Based Metrics in Ultrasound for Estimation of Global Speed-of-Sound
Roman Denkin, Orcun Goksel
Accurate speed-of-sound (SoS) estimation is crucial for ultrasound image formation, yet conventional systems often rely on an assumed value for imaging. We propose to leverage conv…
Learning the Imaging Model of Speed-of-Sound Reconstruction via a Convolutional Formulation
Can Deniz Bezek, Maxim Haas, Richard Rau +1
Speed-of-sound (SoS) is an emerging ultrasound contrast modality, where pulse-echo techniques using conventional transducers offer multiple benefits. For estimating tissue SoS dist…
Weakly Supervised Joint Whole-Slide Segmentation and Classification in Prostate Cancer
Pushpak Pati, Guillaume Jaume, Zeineb Ayadi +4
The segmentation and automatic identification of histological regions of diagnostic interest offer a valuable aid to pathologists. However, segmentation methods are hampered by the…
HDRfeat: A Feature-Rich Network for High Dynamic Range Image Reconstruction
Lingkai Zhu, Fei Zhou, Bozhi Liu +1
A major challenge for high dynamic range (HDR) image reconstruction from multi-exposed low dynamic range (LDR) images, especially with dynamic scenes, is the extraction and merging…
Estimating Mean Speed-of-Sound from Sequence-Dependent Geometric Disparities
Xenia Augustin, Lin Zhang, Orcun Goksel
In ultrasound beamforming, focusing time delays are typically computed with a spatially constant speed-of-sound (SoS) assumption. A mismatch between beamforming and true medium SoS…
Motion Estimation for Optical Coherence Elastography Using Signal Phase and Intensity
Hossein Khodadadi, Orcun Goksel, Sabine Kling
Displacement estimation in optical coherence tomography (OCT) imaging is relevant for several potential applications, e.g. for optical coherence elastography (OCE) for corneal biom…
Content-Preserving Unpaired Translation from Simulated to Realistic Ultrasound Images
Devavrat Tomar, Lin Zhang, Tiziano Portenier +1
Interactive simulation of ultrasound imaging greatly facilitates sonography training. Although ray-tracing based methods have shown promising results, obtaining realistic images re…
Learning Ultrasound Rendering from Cross-Sectional Model Slices for Simulated Training
Lin Zhang, Tiziano Portenier, Orcun Goksel
Purpose. Given the high level of expertise required for navigation and interpretation of ultrasound images, computational simulations can facilitate the training of such skills in…
Training Variational Networks with Multi-Domain Simulations: Speed-of-Sound Image Reconstruction
Melanie Bernhardt, Valery Vishnevskiy, Richard Rau +1
Speed-of-sound has been shown as a potential biomarker for breast cancer imaging, successfully differentiating malignant tumors from benign ones. Speed-of-sound images can be recon…
Ultrasound Aberration Correction based on Local Speed-of-Sound Map Estimation
Richard Rau, Dieter Schweizer, Valery Vishnevskiy +1
For beamforming ultrasound (US) signals, typically a spatially constant speed-of-sound (SoS) is assumed to calculate delays. As SoS in tissue may vary relatively largely, this appr…
Deep Variational Networks with Exponential Weighting for Learning Computed Tomography
Valery Vishnevskiy, Richard Rau, Orcun Goksel
Tomographic image reconstruction is relevant for many medical imaging modalities including X-ray, ultrasound (US) computed tomography (CT) and photoacoustics, for which the access…
SCATGAN for Reconstruction of Ultrasound Scatterers Using Generative Adversarial Networks
Andrawes Al Bahou, Christine Tanner, Orcun Goksel
Computational simulation of ultrasound (US) echography is essential for training sonographers. Realistic simulation of US interaction with microscopic tissue structures is often mo…
