On the Echogenicity of Natural Starch-Based Blood Mimicking Fluids for Contrast Enhanced Ultrasound Imaging: Preliminary In-vitro Experiments
V. Arun Kumar, A. N. Madhavanunni, S. Nivetha +1
Natural starch-based blood-mimicking fluid (BMF) has been used as an alternative to commercially available BMFs for in-vitro Doppler investigations in low-resource settings. Most r…
A Performance Evaluation of Filtered Delay Multiply and Sum Beamforming for Ultrasound Localization Microscopy: Preliminary Results
A. N. Madhavanunni, Niya Mariam Benoy, Mahesh Raveendranatha Panicker +1
Ultrafast ultrasound localization microscopy (ULM), which has shown promising results in microvascular imaging, overcomes the typical trade-off between resolution and penetration d…
Towards Non-contact 3D Ultrasound for Wrist Imaging
Antony Jerald, A. N. Madhavanunni, Gayathri Malamal +1
Objective: The objective of this work is an attempt towards non-contact freehand 3D ultrasound imaging with minimal complexity added to the existing point of care ultrasound (POCUS…
A Simplified 3D Ultrasound Freehand Imaging Framework Using 1D Linear Probe and Low-Cost Mechanical Track
Antony Jerald, A. N. Madhavanunni, Gayathri Malamal +2
Ultrasound imaging is the most popular medical imaging modality for point-of-care bedside imaging. However, 2D ultrasound imaging provides only limited views of the organ of intere…
Learning while Acquisition: Towards Active Learning Framework for Beamforming in Ultrasound Imaging
Mayank Katare, Mahesh Raveendranatha Panicker, A N Madhavanunni +1
In the recent past, there have been many efforts to accelerate adaptive beamforming for ultrasound (US) imaging using neural networks (NNs). However, most of these efforts are base…
Patch Based Transformation for Minimum Variance Beamformer Image Approximation Using Delay and Sum Pipeline
Sairoop Bodepudi, A N Madhavanunni, Mahesh Raveendranatha Panicker
In the recent past, there have been several efforts in accelerating computationally heavy beamforming algorithms such as minimum variance distortionless response (MVDR) beamforming…
A Nonlinear Beamforming for Enhanced Spatiotemporal Sensitivity in High Frame Rate Ultrasound Flow Imaging
A. N. Madhavanunni, Mahesh Raveendranatha Panicker
Typically, an ultrasound flow imaging system employs the conventional delay and sum (DAS) beamformer due to its inherent low complexity. But the conventional DAS technique offers p…
