Summary
Simultaneous optical clearing agents and wavefront shaping significantly improve optical coherence tomography imaging depth and quality. This combined approach enhances signal-to-noise ratio and reveals deeper structures in scattering tissues.
Area of Science:
- Biomedical Optics
- Medical Imaging Technology
- Optical Physics
Background:
- Optical Coherence Tomography (OCT) is limited by light scattering in biological tissues.
- Improving penetration depth and image quality in OCT is crucial for deeper tissue visualization.
Purpose of the Study:
- To investigate the synergistic effects of optical clearing agents (OCAs) and wavefront shaping on OCT imaging.
- To enhance imaging penetration depth and signal-to-noise ratio in highly scattering samples.
Main Methods:
- Concurrent application of OCAs to reduce sample optical inhomogeneity.
- Complex wavefront shaping of illumination light to control multiple scattering.
- OCT imaging of tissue phantoms and ex vivo mouse ears.
Main Results:
- Combined OCA and wavefront shaping significantly enhanced OCT penetration depth.
- Improved signal-to-noise ratio was observed compared to conventional OCT.
- Hidden structures in ex vivo mouse ears were visualized, previously inaccessible.
Conclusions:
- Simultaneous use of OCAs and wavefront shaping is an effective strategy for deep-tissue OCT imaging.
- This approach overcomes limitations of scattering in biological samples.
- Enables visualization of previously obscured anatomical details for enhanced diagnostic potential.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.

01:28Angle Closure Glaucoma: Treatment
1.5K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

13.6K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
