Line-field confocal optical coherence tomography of eyelid margin growths: A case series. [PDF]

Skin Res Technol
AbstractBackgroundThe clinical differential diagnosis of lesions arising on the eyelid margin may be challenging and an unneeded surgical approach may have serious functional and aesthetic consequences. Nonetheless, early recognition and treatment of malignant tumors of the eyelid margin is mandatory.

Immediate diagnosis of cutaneous metastases with optical coherence tomography, line‐field confocal optical coherence tomography and dermoscopy: A case series

JEADV Clinical Practice
Background Cutaneous metastases (CM) are a frequent finding in the follow‐up of malignant tumours. Objectives CM were examined with dermoscopy, optical coherence tomography (OCT), dynamic OCT and line‐field confocal OCT (LC‐OCT) to describe common ...

Gabor fusion technique in a Talbot bands optical coherence tomography system [PDF]

, 2012
In this paper we show how to advantageously combine two effects to enhance the sensitivity with depth in Fourier domain (FD) optical coherence tomography (OCT): Talbot bands (TB) and Gabor-based fusion (GF) technique.

3D Segmentation and Visualization of Skin Vasculature Using Line-Field Confocal Optical Coherence Tomography

Applied Sciences
This study explores the advanced imaging of skin vasculature using Line-Field Confocal Optical Coherence Tomography (LC-OCT), which offers high-resolution, three-dimensional (3D) visualization of vascular structures, especially within skin tumors.

Path-Length-Resolved Dynamic Light Scattering: Modeling the Transition From Single to Diffusive Scattering [PDF]

, 2000
Dynamic light-scattering spectroscopy is used to study Brownian motion within highly scattering samples. The fluctuations of the light field that is backscattered by a suspension of polystyrene microspheres are measured as power spectra by use of low ...

In vivo imaging reveals transient microglia recruitment and functional recovery of photoreceptor signaling after injury. [PDF]

, 2019
Microglia respond to damage and microenvironmental changes within the central nervous system by morphologically transforming and migrating to the lesion, but the real-time behavior of populations of these resident immune cells and the neurons they ...

Intra-operative point-of-procedure delineation of oral cancer margins using optical coherence tomography. [PDF]

, 2019
ObjectivesSurgical margin status is a significant determinant of treatment outcome in oral cancer. Negative surgical margins can decrease the loco-regional recurrence by five-fold.

Electrically pumped semiconductor laser with low spatial coherence and directional emission

, 2019
We design and fabricate an on-chip laser source that produces a directional beam with low spatial coherence. The lasing modes are based on the axial orbit in a stable cavity and have good directionality.
