Texture analysis of ultrasound images obtained with different beamforming techniques and dynamic ranges – A robustness study

•A robustness analysis on quantitative ultrasound texture features was done varying the dynamic range and beamforming method.•Ultrasound image texture parameters are robust to changes in the dynamic range values considered in our study.•Texture parameters are altered when employing different beamforming methods.•Different beamformers could potentially discriminate better between healthy/pathological tissues. Texture analysis of medical images gives quantitative information about the tissue characterization for possible pathology discrimination. Ultrasound B-mode images are generated through a process called beamforming. Then, to obtain the final 8-bit image, the dynamic range value must be set. It is currently unknown how different beamforming techniques or dynamic range values may alter the final image texture. We provide here a robustness analysis of first and higher order texture features using six beamforming methods and seven dynamic range values, on experimental phantom and in vivo musculoskeletal images acquired using two different ultrasound research scanners. To investigate the repeatability of the texture parameters, we applied the multivariate analysis of variance (MANOVA) and estimated the intraclass correlation coefficient (ICC) on the texture features calculated on the B-mode images created with different beamforming methods and dynamic range values. We demonstrated the high repeatability of texture features when varying the dynamic range and showed texture features can differentiate between beamforming methods through a MANOVA analysis, hinting at the potential future clinical application of specific beamformers.
