Acoustic force elastography microscopy (AFEM) can be used to observe the spatial variation of mechanical properties of hydrogels in a non-contact manner and address the limitations of destructive mechanical testing measurements.

Ultra-high-resolution 3D optical coherence tomography reveals inner structures of human placenta-derived trophoblast organoidshttps://www.embs.org/tbme/wp-content/uploads/sites/19/2021/07/TMBE-01565-2020-Highlight-Image.gif170177IEEE Transactions on Biomedical Engineering (TBME)IEEE Transactions on Biomedical Engineering (TBME)//www.embs.org/tbme/wp-content/uploads/sites/19/2022/06/ieee-tbme-logo2x.png
Many pregnancy complications are assumed to have their pathophysiological roots in early stages of placentation. Hence, trophoblast research represents a pre-requisite to help preventing pregnancy disorders that endangers uncomplicated gestations and jeopardizes maternal/fetal wellbeing later in life. Recently established 3D trophoblast organoids (TB-ORG) advanced human placental research. However, gold standard methods for determining TB-ORG architectures lack imaging depth and/or are endpoint analyses. We addressed these problems with 3D optical coherence tomography (OCT). This work demonstrates for the first time that OCT resolves label-free inner structures of TB-ORG during cultivation and enables qualitative/quantitative assessment of their differentiation status without sample destruction.

Optical Coherence Tomography Guided Robotic Needle Insertion for Deep Anterior Lamellar Keratoplastyhttps://www.embs.org/tbme/wp-content/uploads/sites/19/2020/06/TBME-01519-2019-Highlight-Image.gif170177IEEE Transactions on Biomedical Engineering (TBME)IEEE Transactions on Biomedical Engineering (TBME)//www.embs.org/tbme/wp-content/uploads/sites/19/2022/06/ieee-tbme-logo2x.png
Deep anterior lamellar keratoplasty (DALK) is a promising form of partial-thickness cornea transplantation, but its popular “big bubble” technique frequently fails due to difficulty controlling a needle insertion into the cornea. We addressed the surgeon challenges that reduce success rates by demonstrating an optical coherence tomography (OCT)-guided, robotically stabilized workstation for manually or automatically performing DALK needle insertions. In a study with cornea fellows, we found that OCT visualization versus the standard stereo microscope was a key enabler in manual attempts and that our automatic robotic method met or exceeded the performance of cornea fellows.
