Endoscopic Microscopy XII.
Fiber-optic microendoscopes have shown promise as an imaging tool capable of visualizing molecular contrast agents used to study disease in vivo. The small size and flexibility of fiber-bundle probes make them ideal for in vivo use. However, image co

A miniature objective designed for digital detection of Mycobacterium tuberculosis (MTB) was evaluated for diagnostic accuracy. The objective was designed for array microscopy, but fabricated and evaluated at this stage of development as a single obj

Endoscopic Microscopy VIII.
In order to diagnose cancer in breast tissue, a sample must be removed, prepared, and examined under a microscope. To provide an alternative to conventional biopsies, an endomicroscope intended to perform optical biopsies is demonstrated. The system

To reduce the number of invasive tissue biopsies and needle aspirations performed during cancer screenings, endo-microscopes can be used to image tissue in vivo. However, when optical fiber bundles are used to transmit the image, the resolution of su
