Urologic Oncology: Seminars and Original Investigations, 2009
Optical imaging is useful during preclinical drug development for monitoring biomarkers and molecular events in living tissue. In animal models, the technology has been used to monitor tumor growth and metastasis, determine biological effects of novel drugs, monitor tumor enzyme activity, and examine host-tumor interactions.

Optical microsystems for imaging
SPIE Proceedings, 1998We report on micro-optical systems for image projection and image capturing. Our investigations are focused on passive and active array optics, e.g. arrays of micro-objectives, flat camera lenses, Gabor superlenses and moire magnifiers. We discus the potential of micro-optical systems to replace conventional detection and projection systems.

CLEO/Europe Conference on Lasers and Electro-Optics, 1998
Optical spectroscopy is a routinely used clinical laboratory technique, and since the 1930’s has been used to examine tissue oxygenation in thin tissue sections or from surface reflection measurements. However, in the 1970’s the technique of near infrared spectroscopy (NIRS) of intact organs was first described by Frans Jobsis, a breakthrough that ...

Optical Architectures for Compressive Imaging
Frontiers in Optics, 2006We compare three optical architectures for compressive imaging: sequential, parallel, and photon sharing. Each of these architectures is analyzed using two different types of projection: (a) principal component projections and (b) pseudo-random projections. Both linear and nonlinear reconstruction methods are studied.

Optics f2f, 2018
This chapter considers the ability of a lens to produce an image, in particular the effect of the finite size of the lens and the Fourier relationship between the field in the lens plane and the field in the focal plane.

Optical tomography in medical imaging
, 1999We present a review of methods for the forward and inverse problems in optical tomography. We limit ourselves to the highly scattering case found in applications in medical imaging, and to the problem of absorption and scattering reconstruction.

Radiología (English Edition)
The aim of this work is to provide a diagnostic approach to the potential causes of optic neuropathy, focusing on the radiological findings associated with this pathology. Various etiologies have been identified, including inflammatory and demyelinating optic neuritis, developmental and hereditary diseases, neurodegenerative disorders, infectious ...

Optical and Opto-Acoustic Imaging
2012Since the inception of the microscope, optical imaging is serving the biological discovery for more than four centuries. With the recent emergence of methods appropriate for in vivo staining, such as bioluminescence, fluorescent molecular probes, and proteins, as well as nanoparticle-based targeted agents, significant attention has been shifted toward
