52nd DAGA Acoustic Conference in Dresden, 23-26 March 2026
November 2025For the DAGA Acoustic Conference, to be held on March 23–26, 2026, our colleague Łukasz Ambroziński together with Piotr Kijanka are organizing a session titled Biomedical Ultrasound. This section focuses on recent developments in quantitative ultrasound imaging for biomedical applications. These developments include ultrasound elastography techniques, signal processing algorithms, and deep learning methods for solving image formation and reconstruction problems. The scope of the section remains open to other innovative and interdisciplinary contributions relevant to medical imaging and diagnostics.
Internship at Mayo Clinic in Rochester, MN
November 2025Our lab member, Wiktor, completed a research internship at Mayo Clinic in Rochester, one of the world’s leading hospitals. During his internship, Wiktor was involved in:
- Acquiring datasets from different soft materials using the programmable ultrasonic research system.
- Performing validation steps to ensure data quality and reliability.
- Working on, validating, and improving a new signal processing algorithm for Shear Wave Elastography.
- Observing a variety of ongoing lab experiments and taking part in several studies.
New article accepted in Computers in Biology and Medicine
October 2025Our latest research on measuring shear wave attenuation has been published in Computers in Biology and Medicine. This study presents a novel method for evaluating shear wave attenuation using the SAGA-ST approach. The method was validated on analytical data, TM phantoms, and ex vivo tissue experiments. Compared to the 2D-FT and GST-SFK techniques, SAGA-ST demonstrated superior performance, providing lower estimation errors and enabling attenuation assessment over an extended frequency bandwidth. This enhanced bandwidth may facilitate an improved differentiation of viscoelastic materials, particularly at higher frequencies where contrast is more pronounced.
The IEEE IUS 2025 conference, Utrecht, Netherlands
September 2025Our group presented three research works at the 2025 IEEE International Ultrasonics Symposium:
- Shear Wave Attenuation Calculation Using Modified Stockwell-transform-Based Method.
- Local Phase Velocity Imaging with Wavenumber Filter Banks for Improved Low Frequency Shear Wave elastography.
- Reconstructing Shear Wave Dispersion Curves Using Time-Frequency Analysis and Limited Field-of-View Data.
New article accepted in Computer Methods and Programs in Biomedicine
June 2025This paper presents a novel approach for generating 2D shear wave phase velocity images, referred to as LPVI-WBF. This method produces local phase velocity maps closer to the B-mode true shapes and more accurate phase velocity values than existing approaches such as LPVI at low frequencies, as validated by results obtained from inclusion phantoms. Furthermore, for stiffer inclusions, which are of great importance in clinical applications, LPVI-WBF provides a higher contrast-to-noise ratio (CNR) at low frequencies (i.e. below 500 Hz). The proposed method employs an adaptive technique with a 2D Custom Fourier transform (2D CFT) and a 2D Custom Inverse Fourier transform (2-D CIFT), which effectively reduces processing time and memory usage. Variants of the LPVI-WF method enhance the quality of phase velocity maps by improving both the CNR and the accuracy of phase velocity values. Future research will focus on examining viscoelastic materials.
The International Student Grant from the Acoustical Society of America
January 2025Wiktor received the International Student Grant from the Acoustical Society of America (ASA). The ASA provides grants annually to students enrolled in acoustic research programs at universities or technical institutes in developing countries.
New article accepted in Ultrasonics
January 2025This paper presents a novel technique, PL-SWE, for reconstructing shear wave phase velocity dispersion curves and highlights its effectiveness. The study shows that PL-SWE can accurately reconstruct phase velocity dispersion curves in elastic and viscoelastic phantoms, as well as in vivo renal transplant data, with RMSPE values below 6%. Unlike the 2D-FT method, which requires a large number of data points in the lateral direction to produce reliable results, PL-SWE achieves accurate reconstructions with a minimal number of signals (at least two). In addition, the PL-SWE method provides more reliable results than the PG approach for data with low SNR.
Elastography Challenge at the UFFC-JS 2024 in Taipei, Taiwan
September 2024Our advanced methods for analyzing shear wave motion - Ultrasound Shear Elastography with Expanded Bandwidth (USEWEB) and Local Phase Velocity Imaging (LPVI) — were recognized among the top approaches in the Elastography Challenge at the 2024 IEEE UFFC Joint Symposium held in Taipei, Taiwan.
The objectives of this challenge were:
- To challenge the community to devise more accurate and precise algorithms for elastic modulus estimation (via detection and characterisation of propagating shear waves).
- To raise greater awareness of the challenges associated with elastic modulus estimation, and to gain further knowledge on why certain approaches fail.
- To identify the most promising approaches to elastic modulus estimation.
- To provide a benchmark and public data for the future development of SWS and elastic modulus estimation algorithms.
