Enhanced Depth Optical Coherence Tomography Imaging - A Review

Delhi Journal of Ophthalmology, 2014
The choroid remained till date an unexplored entity due to difficulty in visualization of deeper structures in vivo. The choroid being the vascular inner layer receives maximum blood that flows to the eye.

Imaging of the Lamina Cribrosa using Swept-Source Optical Coherence Tomography. [PDF]

, 2012
The lamina cribrosa (LC) is the presumed site of axonal injury in glaucoma. Its deformation has been suggested to contribute to optic neuropathy by impeding axoplasmic flow within the optic nerve fibers, leading to apoptosis of retinal ganglion cells. To

Low Temperature-Mediated Enhancement of Photoacoustic Imaging Depth [PDF]

Scientific Reports, 2018
AbstractWe study the temperature dependence of the underlying mechanisms related to the signal strength and imaging depth in photoacoustic imaging. The presented theoretical and experimental results indicate that imaging depth can be improved by lowering the temperature of the intermediate medium that the laser passes through to reach the imaging ...

A method for measuring the contact area in instrumented indentation testing by tip scanning probe microscopy imaging [PDF]

, 2014
The determination of the contact area is a key step to derive mechanical properties such as hardness or an elastic modulus by instrumented indentation testing. Two families of procedures are dedicated to extracting this area: on the one hand, post mortem
