Multimodal Magnetic Resonance and Near-Infrared-Fluorescent Imaging of Intraperitoneal Ovarian Cancer Using a Dual-Mode-Dual-Gadolinium Liposomal Contrast Agent. [PDF]

open access: yes, 2016
The degree of tumor removal at surgery is a major factor in predicting outcome for ovarian cancer. A single multimodality agent that can be used with magnetic resonance (MR) for staging and pre-surgical planning, and with optical imaging to aid surgical ...

Choroidal Mapping; a Novel Approach for Evaluating Choroidal Thickness and Volume

open access: yesJournal of Ophthalmic & Vision Research, 2012
There are a limited number of non-invasive imaging techniques available for assessing the choroid, a structure that may be affected by a variety of retinal disorders or become primarily involved in conditions such as polypoidal choroidal vasculopathy and

Correlation Plenoptic Imaging With Entangled Photons

open access: yes, 2016
Plenoptic imaging is a novel optical technique for three-dimensional imaging in a single shot. It is enabled by the simultaneous measurement of both the location and the propagation direction of light in a given scene.

Measurement depth enhancement in terahertz imaging of biological tissues

open access: yesOptics Express, 2013
We demonstrate the use of a THz penetration-enhancing agent (THz-PEA) to enhance the terahertz (THz) wave penetration depth in tissues. The THz-PEA is a biocompatible material having absorption lower than that of water, and it is easily absorbed into tissues.

Beyond backscattering: Optical neuroimaging by BRAD

open access: yes, 2018
Optical coherence tomography (OCT) is a powerful technology for rapid volumetric imaging in biomedicine. The bright field imaging approach of conventional OCT systems is based on the detection of directly backscattered light, thereby waiving the wealth ...

Focusing and Compression of Ultrashort Pulses through Scattering Media [PDF]

open access: yes, 2011
Light scattering in inhomogeneous media induces wavefront distortions which pose an inherent limitation in many optical applications. Examples range from microscopy and nanosurgery to astronomy.

Diagnostic Comparison of MRI Sequences for Assessing Myometrial Invasion in Endometrial Cancer: A 1.5T MRI Study

open access: yesHitit Medical Journal
Objective: To compare the diagnostic accuracy of T2-weighted, dynamic contrast-enhanced imaging, and diffusion-weighted imaging in assessing myometrial invasion depth in endometrial cancer and to determine if any sequence performs better.

Photoacoustic computed tomography guided microrobots for targeted navigation in intestines in vivo [PDF]

open access: yes, 2020
Tremendous progress in synthetic micro/nanomotors has been made for potential biomedical applications. However, existing micro/nanomotor platforms are inefficient for deep tissue imaging and motion control in vivo.
