Acoustic Radiation Force Optical Coherence Elastography of the Crystalline Lens: Safety.
Transl Vis Sci Technol

Department of Biomedical Engineering, University of Houston, Houston, TX, USA.
Purpose: To assess the safety of acoustic radiation force optical coherence elastography in the crystalline lens in situ.
Methods: Acoustic radiation force (ARF) produced by an immersion single-element ultrasound transducer (nominal frequency = 3.5 MHz) was characterized using a needle hydrophone and used for optical coherence elastography (OCE) of the crystalline lens.

Optical coherence tomography (OCT) is a technique that performs high-resolution, three-dimensional, imaging of semi-transparent scattering biological tissues. Models of OCT image formation are needed for applications such as aiding image interpretation and validating OCT signal processing techniques. Existing image formation models generally trade off between model realism and computation time.
View Article and Find Full Text PDFThe dynamic measurement range in phase-sensitive optical coherence elastography (PhS-OCE) is limited for the phase decorrelation induced by pixel-level displacements in precision measurement, where the consideration of the time-resolved incremental method and in-plane pixels tracking method is insufficient to recover the phase holistically. This work presented a phase volume correlation (PVC) approach to handle the phase decorrelation in three-dimensional PhS-OCE. By utilizing the ability of the discontinuous source diagram to quantify voxel phase correlation levels, the PVC establishes a wrapped phase-matching equation aimed at optimizing the number of volumetric source distributions.

Article Synopsis
- The study investigates the impact of 3D-printed polycaprolactone (PCL) scaffolds with varying stiffness and porosity on bone tissue engineering and the immune response involved in bone regeneration.
- PCL scaffolds were produced using different techniques, revealing that high-temperature printing creates stiffer structures while low-temperature printing with NIPS results in more flexible, porous scaffolds.
- Results indicated that porosity and stiffness of the scaffolds influence not only the proliferation and mineralization of bone marrow-derived stem cells but also the activation of immune cells, suggesting a complex relationship between scaffold properties and biological responses.
A 3D fast MR elastography sequence with interleaved multislab acquisition and Hadamard encoding.
Magn Reson Med
March 2025
School of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai, China.
Purposes: To enhance the functional capability of MRI, this study aims to develop a novel MR elastography (MRE) sequence that achieves rapid acquisition without distortion artifacts.
Methods: A displacement-encoded stimulated echo (DENSE) with multiphase acquisition scheme was used to capture wave images. A center-out golden-angle stack-of-stars sampling pattern was introduced for improved SNR and data incoherence.
